The tools are electrical equipment de- partment and are not needed for high production the de- partment operates but two three days week under normal conditions. this case, similar cases many other plants, the use automatic tools means that the operators need not specially trained for the particular work question. Thus gang may transferred one several other depart- ments when the electrical de- partment shut down. 882—The Iron April 14, 1932 Waste Gas Utilized Forge Shop CONOMY fuel large forge shop secured pass- ing the waste gases each fur- nace through 150 horse-power water tube boiler. The steam each case sufh- cient operate the hammer which served the furnace. Six seven furnaces and ham- mers are thus connected and all the boilers are interconnected insure uniform steam pres- sure. Better Dies for Die Casting JECTOR pins for use die casting are usually made high carbon heat treated steel. One manufacturer has found considerably greater life for these pins using nitrided steel rod but slightly higher initial cost. the life ex- pensive die greater than the life its ejector pins would probably pay use the nitrided rod. Salt Baths Successful ASE hardening salt bath meeting with success the plant drill manufacturer. The bath used contains two solu- tions—one molten salt used primarily heating agent, and the other, calcium cyanide compound used activat- ing agent. The latter, which added after the bath has reached the temperature, causes the carbon penetration. Keeps Forging Hammer Busy forging hammer frequently runs high per day the labor charge and therefore about important keep hammer busy. Often auxiliary equip- ment such the heating fur- nace demands the attention the hammer operator and cuts down the active hammer time. Each case must studied sepa- rately. One shop operates sev- eral hammers with two men hammer, not operator and each handling the same job and using individual furnaces. order eliminate friction be- tween the two such case, the manager has adopted piece rate pay based the total production the two operators with the amount divided equally between them. Tests Chain Magnetically non-destructive tests steel are still needed and are still sought progressive manufac- turers high grade steel prod- ucts. One such manufacturer has designed continuous and automatic machine for testing steel chain links. this ma- chine the individual links are belt fed through magnetic field, where comparison made be- tween each link and estab- lished standard. Excessive vari- ations from this standard cause pushes the defective link out the line production.
