REDUCTION OF FRICTION DURING WIRE DRAWING BY ELECTRODE CONTROL

In wire drawing, the wire is drawn through a series of dies sprayed wi th or immersed in an emulsion lubricant. The surface conditions of the wire play a vital part in the mechanism of lubrication, and the condi tions can be affected by electrochemical parameters. The electrochemic al behavior of copper in selected emulsions was studied, and laborator y friction as well as pilot plant tests were performed, Reduction of f riction was detected at various potentials depending on the lubricant composition. Surface quality of the wire was improved by the electrode control.
