Problems solved by technology

At the same time, oil-based lubricants have environmental problems because the mold temperature rises to about 300°C during pressing, causing oily fumes, workability (= processability) is poor, and may cause processing defects or cracks
It can be seen that oil-based lubricants have encountered various difficulties in application.

Abstract

Disclosed is a lubricant composition for plastic working which is excellent in workability, degreasing property and working conditions. The lubricant composition is suitably used in fields of plastic working, particularly in fields of warm press forming, of various metal materials, especially of magnesium-base or aluminum-base nonferrous metal materials. Also disclosed are a warm forming process using such a lubricant composition and a method for producing a warm press-formed metal material. The lubricant composition for plastic working contains a solid lubricant and (B) at least one selected from (i) calcium sulfonates and (ii) non-volatile compounds, and the mass ratio between the component (A) and the component (B) in the composition is from 90:10 to 10:90.

Description

technical field [0001] The present invention relates to a lubricant composition for metal forming, a cold working method and a warm working method using the lubricant composition, and a method of producing a metal material for warm press working. More specifically, the present invention relates to a lubricant composition for metal forming, which is excellent in handleability, degreasing performance, processing environment, etc. and is preferably used in the field of metal forming, particularly preferably in various metal materials, especially magnesium The field of warm-press processing of base or aluminum-based non-ferrous metal materials relates to a warm-press method using the lubricant composition and a method for efficiently producing warm-press processed metal materials. Background technique [0002] Hitherto, lubricants have been used in the forming of metals to: reduce the friction between the metal material and the tool or die; make the plastic deformation of th...
