用铝合金粒加工的半成品大多数是用金属压力加工车间的设备生产的.因此,铝合金粒轧制产品是按以下流程生产的:把合金粒压成块坯→挤压块坯→轧制挤压好的坯料.每一阶段采取的压力加工参数对最终半成品的性能都有很大影响.关于合金粒的第一个加工阶段——压成块坯——大多数研究人员的意见是一致的:块坯在400-450℃左右的温度和能保证达到接近理论密度的压力下成型.以后加工阶段的热机械制度必须根据对半成品的几何形状、组织、物理力学性能及其他性能来选择.
The majority of semi-finished products made of aluminum alloy pellets are produced by a metal press shop, so aluminum pellets are produced by the following process: pressing the pellets into a block → extruding the block → rolling Squeeze the good billet each step of the pressure processing parameters on the performance of the final semi-finished products have a great impact on the first stage of the alloy particles - pressed into lumps - most researchers agree : The billet is molded at a temperature of about 400-450 ° C and a pressure that can be guaranteed to reach a theoretical density.Afterwards the thermomechanical system at the processing stage must be selected based on the geometry, organization, physical and mechanical properties, and other properties of the semi-finished product.
