Steel wires are made by passing wire rods through conically converging dies. As a result of the pulling force on the wire rods through the converging section, the diameter of the wire is reduced. This reduction in diameter of the wires is a gradual process, and it takes place by passing the wires through a sequence of dies with gradually decreasing converging sections. These wire drawing dies are made of sintered tungsten carbide (WC).
For the purpose of lubrication, dry lubricants are used which forms a thin layer between the wire and die surface to prevent direct contact between wire material and die & reduce friction. Calcium and sodium stearate soap powders are mainly used as dry lubricants.
We are seeking alternate uses of this used soap powder, either as an alternative fuel or as raw material.
