Abstract

The disclosure concerns the field of metallurgy and relates to a method and device for use in the forming of wire-shaped metal material, in particular in wire drawing. To form and/or coat wire-shaped metal material with solid to paste-consistency lubricants, the material is passed through a pressure chamber fitted with at least one inlet nozzle and at least one outlet nozzle. Located in the pressure chamber is a solid to paste-consistency lubricant which is under pressure. The pressure is set and/or regulated and raised by means of an external pressure-generation unit. The combined pressure/temperature setting used for the lubricant is always kept below the level at which the lubricant would liquefy. The lubricant is used as a powder or in the form of shaped articles, preferably compacts, pellets or granules, and fed to the pressure chamber from lubricant-storage facilities through feed channels.
