Abstract

To remove scale and rust from transformed metal materials, and especially drawn wires, it is covered by an enclosed shrouding of a lubricant and the cross-section is reduced with a degree of reshaping of >=3%. After drawing through a die, the lubricant is removed together with any scale or rust.
