一、前言 目前,国内外钨、钼棒材的生产基本上采用热加工方法,热加工的加工道次多、工艺繁杂。同时,高温下加热金属损失较大,吸入有害气体,使材料性能变坏,制品性能降低,难以满足用户要求。 静液挤压加工方法是使金属在高压液体作用下变形,消除了坯料与挤压筒之间的摩 I. Preface At present, the production of tungsten and molybdenum bars at home and abroad basically adopts the thermal processing method, and the thermal processing has many processing passes and the processes are complicated. At the same time, high temperature heating metal loss, inhalation of harmful gases, the deterioration of the material properties, product performance decreases, it is difficult to meet user requirements. Hydrostatic extrusion processing method is to make the metal deformation under the action of high pressure liquid, eliminating the friction between the blank and the extrusion cylinder
