It is very conspicuous that the effect of drawing plastic deformation metal wire with roller die is better,but some broken wires often appear when it is used for drawing wire,especially special-shaped wire of low plastic deformation metal.
结合轧制的特点,将被动式辊拉模变成主动式用于拉拔低塑性金属异型材。
The production process become very difficult when non-ferrous metal of lower plasticity is broken.
拉伸、辊拉为二向拉应力、一向压应力,所以对塑性较好的金属线材有利,而对低塑性有色金属材料不利,后者加工时易出现拉裂或拉断现象,造成生产中断甚至无法加工;轧制法应力特点为三向压应力,对塑性较好或低塑性金属线材都有利,但型辊加工昂贵,轧机维护费用高,故轧制法最好用于大规模生产中。
