  • a lubricant applied to the material to be formed prior to the forming is necessary for the drawing of extruded metal.
  • Such lubricants can be classified according to their physical state, among other things. A distinction is made between solid lubricants, paste-like and liquid lubricants. In the group of solid lubricants, a distinction is made between those used in powder form (Bartz, W.

  • This method avoids the generation of lubricant dust, but its decisive disadvantage is that it is very complex and requires a relatively large amount of space and time for drying.

Abstract

L'invention se rapporte au domaine de l'extrusion de produits de formage allongés et à celui des lubrifiants solides utilisés à cet effet. Le lubrifiant solide produit selon l'invention peut être appliqué sur le produit de formage, afin d'en permettre l'extrusion ou de la simplifier. Ce lubrifiant solide se caractérise en ce qu'une ou plusieurs substances solides s'utilisant comme lubrifiants dans des processus d'extrusion sont traités pour former des corps moulés. Chaque charge de corps moulés comprend des corps moulés à la géométrie et/ou aux dimensions identiques ou différant les unes des autres, de manière à éviter les fractions produisant des poussières. Afin d'éviter ou de réduire les phénomènes d'abrasion ou de rupture, la surface des corps de moulage est durcie ou recouverte d'une couche de protection. Les corps moulés peuvent également être recouverts ou imprégnés d'une substance hydrophobe, d'une substance non hygroscopique ou d'une substance faiblement hygroscopique. Lors de la fabrication, les corps moulés sont produits, de manière à éviter la formation de fractions produisant des poussières, par des procédés de formage tels que la compression de poudre, sous forme de boulettes, de granulés, de briquettes ou de produits façonnés.
