摘要

A process for the lubrication in the hot deformation of metals, especially in the extrusion of steel, characterized in that, as a lubricant, a water-soluble salt is used which melts at a temperature lower than that of the metal deformation, for example a carbonate or alkali halide, or a mixture of salts, for example, in carbonates or alkali halides, salt or mixture which, before being used as a lubricant, has been heated to a temperature equal to or higher than the temperature of its point of transformation or its first point of transformation.
