Established 1855 NEW YORK oREWICAL WBBAR September 23, 1920 FAY AUTOMATIC LATHE (FLANDERS TYPE) ‘“‘Most Powerful 14in. Lathe Built ’’ This seems like a strong statement but in view of the detailed information given below we believe it to be so. The driving pulley is 15 in. dia. with a 5 in. belt. Regular speed is 706 R. P. M., giving 166,348 sq. inches belt surface per minute. The front journal spindle has 544 in. dia. x 5% in. face. The rear journal spindle has a 5 in. dia. x 5% in. face. It is furnished with a heavy ball thrust bearing. The rest of the machine is built in proportion. We believe that this is not only the strongest 14 in. lathe built, but that it would be hard to find a 24 in. lathe as strongly built and driven. In fact there are few 30 in. lathes that can beat it. JONES & LAMSON MACHINE COMPANY, “Vessonr” ESTABLISHED 1855 Steel Plant Operated with Waste Heat New Works of Electric Steel & Forge Co., Cleveland, for the Manu- facture of Alloy Steels—Ingots Broken Down Under a Hammer RECENT addition to plants engaged in the marufacture of alloy steels with the use of electric furnaces is that of the Electric Steel & Forge Co., Cleveland. This company is the successor of the Crucible Steel Forge Co., that had long been engaged in the manufacture of crucible steel in Cleveland. Some time ago the Company was reorganized under its present name, 4 new site was secured covering a fifteen-acre tract on Grant Avenue, and the Belt Line Rail- road, and on this a new plant was recently erected It has a capacity of 800 tons per month and is for the manufacture of various alloy steels of high quality for a wide range of uses and also for making heavy finished forgings.

The plant includes a cogging shop in whic: the ingots are broken down and large forgings are finished, and a hammer shop in which the forg- ings in smaller sizes are finished. These two de- partments occupy adjoining buildings not sepa- rated by a partition. In the same parallel line on the other side of the cogging shop is the billet vard. The melting department occupies a sepa- rate building and another houses a heat-treating department which is used for heat-treating bars and finished forgings. The plant has a 6-ton Heroult electric furnace and a 4%4-ton Moore electric furnace, the latter be- ing provided for making high speed steel and for special melts. The furnaces are located at one side of the melting shop, which is 220 ft. long and 10 ft. wide. Space is provided for the installation of an additional 6-ton electric furnace. The build- ing is served by a 20-ton and a 5-ton Pawling & Harnischfeger crane. Departing from the usual practice the Heroult furnace is operated on two voltages, running at 120 volts when melting and at 90 volts when refining. With a higher voltage rapid melting is possible, but it is stated that were 120 volts used for refining, the high furnace tem- perature would burn out the lining. No pig iron is used in the furnace charge. In order to get high quality steel, the material used as the basis for the charge is selected low phos- alte ta mee ~ * (66 THE IRON AGE phorus melting in shoveling size, such as nickel, chrome vanadium and carbon tool steel, and muck bar grades. The scrap yard is conveni- ent to the melting shop and occupies a space 80x 100 ft. It has bins for the storage and protection of various grades of scrap and is served by a 10- ton 80-ft. monorail crane equipped with a lifting magnet. The crane was furnished by the Cleve- land Crane & Engineering Co. A railroad siding extends along the outer side of the billet yard and across the melting shop through the scrap yard adjoining.

They have pyrometer control, and are fired with Jones underfeed stokers. Coal and ashes are handled at the back, leaving the front of the furnaces free for handling the steel. Ove. head coal bins for each stoker are provided, these being filled by the outside yard crane. The furnace doors are operated by air lifts controlled from a convenient point at the front of the furnace. The doors are designed for the quick removal of the brick lining when replace ment is necessary and are so constructed that the lower half of the door can be easily replaced. The door is made of two castings, being in two sections. The brick in the upper part is held in nf Molds Standing in the Pit at One End of the Melting Shop Ready for Pouring ee 768 place by a rib. The lower part of the door is lined with a brick of a special shape, held to the door by hollow spindles which extend through the front of the door and part way through the These hollow spindles tend to radiate heat quickly from the door lining, keeping the tem- perature of the lining down somewhat. In designing the waste heat boiler installation it was decided, because of the intermittent opera- bast ale DYrickK, tion of the heating furnaces, to have two fur- naces connected to each boiler, making three sets f two furnaces each and three boilers. A 200- hp. water tube boiler is mounted over each fur- nace. The boilers are equipped with induced draft fans to overcome the boiler resistance. A complete and flexible system of control is provided by having flues for by-passing the gas past the boilers, or any one boiler, into a long hori- contal flue to the stack.

The forge shop is equipped with e large rough-turning lathes for turning billets into ro ad bars, piston rods, etc., and with 10 grinders and 30 chipping hammers for finishing billets before roll. ing. The plant will include finishing mills, which will be housed in an extension to the present main forge shop, making this building when completed 700 ft. in length. The billets will pass down th building from the forging hammer to th and chipping hammers, and then to the rolling mills at the lower end. The extension will also include a shipping department. At present the billets are sent to the mill of the Cleveland Rolling Mills for rolling into bars. Foundations for mill department are now in. The contract for the mills has been placed with Mackintosh, Hemphill & Co. There will be three stands of 16-in. mills, five stands of 10-in. mills and two stands of 8-in. mills.

Behind the fur- The Allis furnace can be used in conjunction wit! nace a pusher is provided, either hydraulically or any of the fuels that have been mentioned, but it js electrically operated, and the bars are pushed not particularly recommended for use with coal hand through automatically. This insures a very even heat- ing of the bar, reduces manual labor, is economical in the use of fuel and, most important of all, does not re quire highly skilled labor. Under all the older tems, the heater had to move his bars from one part of the furnace to another, turn them and edge them. This not only required experience and skill, but a very considerable amount of manual labor, during which the heater or operator was exposed to the heat of the open furnace. In the Allis furnace the bars come through on edge, so that they have practically all surfaces ex- posed to the action of the heated gases. At the end of the V grooves there is a short forehearth which heats up any black spots caused by contact with the and all the heater’s helper has to do is to open the furnace door and take a pair of bars and pass these to the roller, which means a few seconds expo sure only. The heater attends to the pusher and reg- i! ulates the heat of the furnace by means of his control lampers. The V grooves are usually steel castings and are staggered so as to allow a greater impingement of the flame on the bars. Four or five heats can be carried n one charge. The bars pass through the furnace in in angular position. As each of bars the same heat zones every molecule of soaking heat, and thus the bars are harged on the forehearth in a mellow condition. sys- ) vrooves, ] set passes stee] dis The iA ae re NG through eceives a Vo. nt 7 ds To 4] Baoqnagae O bE ———— ICIC ICIC IC 1 Tart om —<fICICICICIC } HY aH 1 et ee Vr oe ~ C } Allis Continuous Pair Furnace fired; in fact, it is the ideal combination wit} derfeed stoker. the ul Temperature and Draft Regulation Too great stress cannot be placed upon the vi need of regulation, whichever type of furnace is d cided upon. This primary requisite must never for moment be lost sight of; there must be n violent changes in the intensity of the temperat must the flame be allowed to localize on any one ; tion on the hearth. Therefore, in designing furnace for heating sheets and pairs it is essential to hav flues of ample area and so distributed on the exit er that the pull of the stack is equalized. The regulation of the draft in a natural draft stack is accomplished by a bonnet damper. Thi apy at the top of the stack and balanced so that the pull slight, about 40 lb., and the hand lever is arranged t hook into a rack conveniently placed on the of the furnace. The damper is usually be fully open when in the normal position. The essential condition of ample flue area appli to the cases where the products of combustion ar to underground flues. The dampers in these cases al arranged in the flues, balanced as before, and actuat by means of wire rope and pulleys. The handle, usua a rod, is arranged to hook into a rack on the fur bindings. The damper regulation should b as seldom as possible. 1d ce! binding ] arranged Evolution in Furnace Construction In the older types of furnaces the bu cast iron of T section, with bosses to ac the tie rods at the top and bottom.

Reinforced plate and angle construction with flat top, a very heavy and scientifically constructed box of long life and free from warpage. Annealing furnaces, like sheet and pair furnaces, are of many varieties, but these varieties are only of detail. Essentially they are of two types, the in-and out furnace—that is, charges put in and taken out through the same door—and the continuous type, in which the charges are put in at one end and after an nealing are taken out through doors at the other end The general layout of the plant decides which is the better type, but as a general rule the in-and-out fur nace lends itself more readily to the economical han dling of the product. Charging Methods An annealing furnace is essentially a tunnel con- sisting of side walls, bridge walls, combustion chamber or chambers, and annealing chamber. It may be ar- ranged for one or two boxes or stands, side by side, and either one or two boxes deep on the hearth. What- ever type is adopted, it is essential that it be so ar ranged that no flame impinges directly on the boxes. The old method of charging, still very much used, is known as the cannon-ball method. A V-shaped rail is laid in front of the furnace and the entire length of the furnace on the hearth. The stands have inverted V grooves on the bottom. A series of loose cast iron balls about 6 in. in diameter are placed haphazard on the V-shaped rail. The stands and covers rest on these balls and it is, of course, a simple matter to propel the stands in and out of the furnace. Many methods of trucks with wheels, rollers, ete., have been tried but have failed, on account of the heat to which they are subjected in the furnace, and, of course, the correspond- ing contraction on cooling on being withdrawn. One modern method consists of a swan-neck charger operated by an electric traveling crane. Suitable stands of refractory material are built on the furnace emer nme 7 ~] bo hearth, usually in the shape of piers. The stands are flat bottomed in this case and are packed on similar piers on the outside of the furnace. The charger lifts the stand, plates and covers, and places the charge in the furnace and withdraws it in the same manner. This method is clean, quick and economical, and has the great advantage of leaving an absolutely clean floor in front of the furnace for trucking, etc. The loading piers may be out of the way on the opposite side of the mill close to the black pickle. This method is not ap- plicable to sheets on account of their comparatively greater length. Typical In-and-Out Furnace Fig. 4 shows a typical annealing furnace of the in-and-out type arranged for stoker firing. The hearth of this furnace is arranged for the older type of charg- ing by means of cannon balls and rails. The combus- tion chambers extend continuously from the front to the back on both sides. They are separated from the hearth by bridge walls over which the products of combustion pass. The bridge walls are so arranged that the flames do not impinge directly upon the an- neiling covers, the object being to bring the covers and stands up to heat slowly, a soaking heat rather than a welding heat being required. After passing over and around the covers, charges and stlinds, the gases are led through staggered flues in the center wall to the underground flues which lead to the stack. The bridge walls are 18-in. first quality firebrick, carried comparatively high towird the crown of the furnace in order to protect the annealing covers from direct impingement of the flame. The bridge walls are also improved by corbelling, as in the case of the heat- ing furnaces. It is most economical to build two hearths side by side, so that an annealing furnace takes eight stands and covers, two on each hearth and two deep. In this case the division will is 22% in. thick, of first quality firebrick. The extra course of brickwork makes it much easier to accommodate the staggered flues lead- ing downward to the stack flues which run parallel to each other underground. It is necessary to provide two sepanite flues to the stack in order to provide separate damper regulation for each hearth. The dampers are at the rear of the furnace and are operated from the front by me ins of wire ropes running over a series of pulleys. Dampers must be capable of regula- tion from tight shut to full open. When the boxes have been exposed to the flame in the furnace for 12 hours the dampers are shut down tight and the stokers stopped. The boxes are allowed to remain in the furnaces 12 hours and then the @ympers are opened wide, when the stack draft removes all fumes, etc., from the hearths, and the boxes can be removed and new charges placed. The stokers are started up again and the operation is repeated. The doors on annealing furnaces are usually hinged, and not sliding and balanced as in the case of heating furnaces. The doors being operated but once a diy, such construction on the whole is to be preferred. The front of the furnace is covered with a heavy cast iron plate extending from the bridge wall buckstay to the center wall and to the crown of the arch. On this plate are cast lugs to accommodate corresponding lugs on the doors. The doors are cast in two halves and dished out to accommodate a lining of 4% in. of fire- brick. One of the halves of the door casting has a lip 3 to 4 in. wide cast on in such a minner that it seals over the other half, and lugs are cast on each half of the door at one-quarter the way from the top and bottom, to accommodate a 4-in x l-in. bar which is wedged in to lock the doors. Each half of the door should be provided with two peek holes and to lighten the doors a series of circular holes are cored in as shown. The buckstays are 7-in. standard channels buwk to back with 1%-in. tierods. At the top and bottom of each pair of buckstays a suitable casting is arranged with 1 3-in. boss not less than 3 in. thick to accommo- date the tierods. The stoker fronts are of cast iron, and as they cover nearly the whole of the side of the furnace it is wiser THE IRON AGE September 23, 1999 to plate the whole of the furnace as this f: making the necessary repairs to the brickwo) stoker fire inspection doors are balanced sliding 4, while the ash pit doors are hinged.

It is customary to have one fan to supply the pres. sure air (about 2 oz.) to the stokers for sheet, pair « annealing furnaces. This pressure is piped galvanized piping to the wind boxes of th stokers. Fuel Consumption A word as to fuel and fuel consumptio Many kinds of fuel can be used on sheet, pair and annealiy; furnaces. Natural gas is the ideal fuel but t] is uncertain and daily becoming more so. Fue! 5 an excellent fuel but is more expensive than moder methods of coal firing, and the supply is no 1a in all localities. Coal hand-fired uses between 450 600 lb. per ton of product, depending entire) personal equation, and it requires very sharp vision on the part of the management to keep lower figure. Coal stoker-fired is the most successful using run of mine coal. Continuous runs hav made at 380 lb. of coal per ton of finished prod sheet and pair furnaces, and 240 lb. for annea naces. In the author’s opinion the use of pulve coal is to be preferred, particularly where more tha 10 mills are installed. This number of mills means that the expense of installing the necessary crushing and pulverizing plant is spread over a greater quantit) of product and this reduces the price per ton for terest charges. A sheet mill at Niles, Ohio, reports under 275 lb. of coal for sheet and pair furnaces and under 170 lb. of coal for annealing furnaces. Doubt less these figures will be considerably improved as the operatives become more used to the system Indicted on Charge of Conspiracy to Defraud PITTSBURGH, Sept. 18.—A true bill was returned | the grand jury yesterday charging Lakin C.

Vs ee rete — 774 Oilstone Wet Tool Grinder An oilstone wet tool grinder equipped with three grades of stones for general tool grinding in machine shops and tool rooms is a recent product of the Mum- mert-Dixon Co., Hanover, Pa. There is one 16 x 2-in. coarse grained, fast cutting wheel for quickly grinding heavy tools, a 10 x 2%-in. medium grained wheel for ordinary grinding, and a 10 x 2%-in. fine grained wheel for grinding scrapers and putting the smooth, velvety edge to tools. Kerosene is used on the wheels, thus to prevent glazing and keep the wheels clean and sharp, and also to prevent the tools from overheating. It is also pointed rh net out e ust erosene Is more agreeable to the workman than water, as water always rather objec tionah!] n connection with greasy hands. The kero- sene listributed to the wheels by a small centrifugal pun ted at the bottom. of the oil reservoir.

The regular equipment includes a_ ball-bearing cou! haft for the belt-driven machine, and one motor belt tightener for the motor driven machine. The net weg with motor is 1300 lb., and net weight without motor, 1075 lb. The floor space required is 33 x 41 in. St. Louis Campaign for Manufacturing Plants The St. Louis Chamber of Commerce has organized a New Industries Bureau, which has started a cam- paign to bring new manufacturing plants to that city. The industries St. Louis is seeking are in the following lines: Blast furnaces, malleable iron castings, screw machine products, farm implements, rubber products, locomotive works, cotton spinning and textile mills, steel and copper wire, machine tools and tool machinery, au tomobile and parts, tanneries and leather goods, shoe and findings, cork products, small hardware, dyestuffs, drop forge plants. A booklet en- titled “St. Louis as a Manufacturing Center” gives de- tails as to the qualifications of St. Louis as a manu- facturing center for various products. For example, in citing its advantages as a site for blast furnaces this statement is made: “One-twentieth of all the coal mined in the world is mined within a radius of 100 miles of St. Louis. This coal can now be coked for blast furnace use. A battery of 40 coke ovens now in operation and a new $8,000,000 plant with 80 ovens, using the new process, accessories laces THE IRON AGE September 1920 nearing completion, will furnish plentiful cok blast furnaces and gas so essential for iron treatn Mis sissippi River transportation brings ore & ically from the vast deposits of the Northwest.” ; The claim is made that St. Louis is desi to b come a steel center of the Middle West. It YW said to be the greatest open-hearth steel casting er the United States. Another statement of lirector of the New Industries Bureau is that 80 ent of a railroad locomotive is made in St. Louis. ‘The on) parts not made in St. Louis are the tube boiler sheets and tires for drive wheels. ectors New Branch of Henry Disston & Sons, Inc.
