On the Wire Drawing Lubricant

Abstract

However very important the performance of lubricant for the drawing of medium or high carbon steel wire is not only for the efficiency of the work, but also for the quality of the drawn wire, only few of systematic approaches to wire drawing lubrication problems have been reported. The author investigated performances of many lubricants under elevated die temperatures, and confirmed that they dominate the efficiency of lubricants under practical drawing conditions. From this point of view, he investigated many lubricants especially the mixture of lime and soap, and made clear the coating effect of solid lubricants. He also examined and improved metallic soaps and phosphate coatings. On the other hand, he investigated the effect of die cooling.
