ABSTRACT:
Herein disclosed is a dry type continuous wire drawing process which can retain satisfactory working circumstances while eliminating the problem of disposal of waste liquids. The wire drawing process includes the steps of descaling a wire to be drawn, coating the descaled wire with a lubricant, and drawing the lubricant-coated wire through a drawing die. The descaling step is conducted in a mechanical manner. At the lubricant coating step, the descaled wire is once coated with lime powder and then with metallic soap powder. Thus. the three steps recited are conducted under dry and continuous conditions. At the lubricant coating step, the lime-coated wire may be coated with powder of sodium stearate before it is coated with the metallic soap.
