众所周知,在进行钛等金属坯料的热挤压加工时,为了延长模具的寿命,减少被加工的热金属和模具的摩擦阻力,防止挤压坯料的局部加热,必须在挤压坯料和模子间进行适当的润滑。多年来,国外试用过多种挤压润滑剂,取得了一些可供我们参考的经验和教训一、玻璃垫润滑及其缺点从前,为了挤压金属材料,国外曾经采用过二硫化钼,石墨和玻璃等多种材料,分
It is well-known that during the hot extrusion process of a metal material such as titanium, it is necessary to conduct the extrusion of the metal material between the extrusion material and the mold in order to extend the service life of the metal mold, reduce the frictional resistance of the metal material to be processed and the mold, and prevent localized heating of the extruded material Appropriate lubrication. Over the years, many kinds of extrusion lubricants have been tried abroad, and some experiences and lessons have been gained for reference. 1. Glass mat lubrication and its disadvantages In the past, in order to extrude metal materials, molybdenum disulfide, graphite and Glass and other materials, points
