METHOD AND DEVICE FOR FORMING AND/OR COATING WIRE-SHAPED METAL MATERIAL

摘要

The invention concerns the field of metallurgy and is suitable for use in the forming of wire-shaped metal material, in particular in wire drawing. To form and/or coat wire-shaped metal material (19) with solid to paste-consistency lubricants (18), the material is passed through a pressure chamber (14) fitted with at least one inlet nozzle and at least one outlet nozzle. Located in the pressure chamber (14) 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 (1). The combined pressure/temperature setting used for the lubricant is always kept below the level at which the lubricant would liquefy. The lubricant (18) is used as a powder or in the form of shaped articles, preferably compacts, pellets or granules, and fed to the pressure chamber (14) from lubricant-storage facilities (15; 16) through feed channels (8; 9).
