Mills Nos. 1, 4, and 5 are driven by two motors, one located on each side of the mill stands, the other motors togetner with auxillary equipment being located in a lean-to opposite the mills. The No. 4 or intermediate stand can be driven either with the No. 1 or No. 5 stand. The drive to No. 4 mill is through the middle and top pinions from the middle and bottom pinions of No. 1 or No. 5 stands, and the drive of No. 3 stand from No. 2 is similarly arranged, the stands having 3-high pinions. With a higher speed provided for the No. 5 stand a greater range of speed 1S available intermediate stand because of the arrangement to connect it to either of the adjoining stands Nos 1 and 5 that have different speeds. Between the Nos. 1, 4, and 5 stands, and the Nos. 2 and 3 stands, a transfer is provided similar that below that when rolling thick gages the material passes only through 1, 4, and 5 stands, the two lower stands, Nos. 2 and 3, being elimi- nated. From the finishing mill the product passes to a transfer table and cooling bed, 185 ft. long and 22 ft. 6 in. wide, provided with a ratchet transfer. If the material is to be coiled it passes straight alg the latter stands so tc own the runout table to a vertical shear at on d the lower end of the transfer where the ends are trimmed off as desired, and it goes from the shear into a coiler. If it is to be shipped out in flat strips it is slowly carried over the transfer and cooling bed to the runout table on the opposite in ‘ > . : ‘ . ar « . | ah " >» £4 side and carried on a shear approach table 246 f long to another vertical shear where it is cut to length and placed on trucks. The runou abie to the coiler is divided into two sections, the trans ? fer into three sections, and the runout on the } opposite side into four sections, and any one sec- tion of each can be operated independently of the other sections. Each section is operated by a variable speed motor. The electrical equipment of the hot mill con- sists of four adjustable speed alternating current induction motors for driving the main rolls. These include one 1500-hp. 360-r.p.m. motor, and three 1200-hp. 360-r.p.m. 60-cycle 3-phase 2300- volt mill-type wound-rotor induction motors, the larger motor driving the 20-in. mill and the three smaller motors the 16-in. mill. Each motor is pro vided with a double range Scherbius speed regu lating equipment to give a speed range of 450 to 270 r.p.m. The larger motor has a continuous rating of 1500 hp. from 450 r.p.m. to synchronous speed, and 1200 hp. at 270 .r.p.m. The three smaller motors have a continuous rating of 1200 r.p.m. at all speeds from maximum to minimum. The speed regulating equipment con- sists of a 360-kva. commutator type alternating- current motor direct connected to a 275-kw. 2300- volt induction generator running at 514 r.p.m. This equipment provides practically a continuous speed range from maximum to minimum. The commutator motor impresses a _ voltage on the secondary or rotor of the main motor of such value as to give the desired speed regardless of variations in the load; the main motor, how- ever, retains all the normal characteristics of an induction motor running without speed regulating 178 THE IRON AGE February 20), j9j9 equipment.

The finished product is handled after | the shears on trucks hauled by a Jeffrey storag battery locomotive that runs on tracks in the part of the plant and to the pickling depart: 1 to an outside shipping platform.

The cold-rolled strip department is d for the manufacture of strips in a wide rang sizes and for accuracy of product, and among features is the high operating speed of the This department is equipped with four set rolls, 16 in. in diameter and 20 in. wide fo ing strips, 8 to 16 in. wide, four sets of 12 rolls for rolling strips 3% to 8 in. wide, a! sets of 8 x 10 in. rolls for rolling 1 t widths.

There are two single slitte: of which can be operated either independent with an adjoining single set of rolls, one 12 x 16 in., and the other with 8 x 10 in. ros In case of further reduction after slitt material passes directly from the slitter rolls, combining the two operations. Wh slitter is used independently of the mill a cutting the steel into narrow strips, six or elf pieces can be slit at one time. Below the two set of rolls that work with the slitters are tw y sets of 10 x 16-in. and 8 x 10-in. rolls, the smaller set being provided with an edging machine oe low these mills are two combination slitters an© mills.

THE IRON AGE 487 HIGH COST OF TOOL BREAKAGE Shop Operations Interrupted and Overhead Costs Increased—Tool Damage Reports To reduce tool breakage, a complete record of each broken tool is kept by the Willamette Iron & Steel Works, Portland, Ore. When the tool is turned in, it is accompanied by a tool damage report which must be turned in at the same time to obtain another in- strument. This report also explains the cause of breakage and is sent to the machine-shop superin- tendent’s office each day, where a record is kept of both tool damage and the division of cost against each shift and department. The records are a convincing testimony to the ex- pense of putting good tools in the hands of careless or incompetent workmen; and a charting of tool breakage shows that it is particularly heavy when numbers of new men are being put to work. Even in normal times the company found that the damage to tools is a big problem and that careless men can destroy in @ moment tools far in excess of the value of their labors for weeks and n onths. It 3 tated that this actually happened on one or two occasions at the plant. But greater than the loss in m ney 1s the fact that it is in some cases almost impossible to replace at once many special high-speed tools that are destroyed. Breakage, therefore, of several important in plements at about the same time compelled the plant to lay off a machine and hold up the entire progress of production. The amount of supervision necessary over such incompetent men is shown by the following figures. Before labor turnover became a problem last fall, two tool room clerks with eight assistants easily dispensed the equip- ment required by 500 men, whereas toward the end of the year 39 were required and 11 mea were engaged ’ solely on grinding the tools.
