至今常用的制造金属丝材的方法,是将金属加热熔化浇铸成锭,然后通过扒皮、挤压或者锻造和轧制成一定尺寸,再进行反复拉拔,中间还需进行必要的酸洗和热处理等。对于某些塑性变形能力差的金属,则需进行热加工,因此工序繁杂,加工周期长,丝材 The common method of manufacturing metal wire so far has been to heat and melt the metal into an ingot which is then drawn, extruded or forged and rolled to size and then drawn repeatedly, with the necessary pickling and heat treatment Wait. For some poor plastic deformation ability of the metal, you need to heat processing, the process complicated, long processing cycle, wire
