A LUBRICANT AND A MAKING METHOD FOR EXTRUDING MAGNESIUM ALLOY |
摘要 |
Lubricant for extruding magnesium alloy is provided to reduce frictional pressure during the extrusion process so as to increase of extrusion speed, and reduce frictional heat so as to prevent of surface oxidation or crack by comprising base oil, friction inhibitor and additives for obtaining load resistance and releasing property. The lubricant is prepared by admixing: 50-94wt.% of organic compound as base oil; 5-40wt.% of metal soap as friction inhibitor; and 0.5-20wt.% of molybdenum disulfide and 0.01-5wt.% of boron nitride as additives for endowing load resistance and releasing property to the lubricant. The organic compound consists of silicon oil, the metal soap consists of lithium soap, and the additive consists of molybdenum disulfide and boron nitride. The lubricant is used to extrude magnesium alloy from an extrusion device(2) which is fabricated of a container(4), a cylinder part(6) and a piston part(8) fixed to rear of the cylinder part(6) to press a billet(b) fed into the cylinder part(6). |
