通常的有色金属线材,一般是通过熔炼、铸造、开坯、轧制及拉伸加工生产的。管材或复杂断面的型材则用专用轧机、立式或卧式挤压机加工成型,其尺寸规格都较大。小规格的管材还须再采用拉伸工艺生产,而用连续挤压法,可直接主产出各种品种规格的小型管材和微型型材。连续济压是指坯料(连铸坯、拉拔或连轧盘条及粉末颗粒料等)连续地送避挤压机 The usual non-ferrous metal wire, usually by melting, casting, billet, rolling and drawing production. Pipe or complex cross-section profile is a special rolling mill, vertical or horizontal extrusion molding machine, the size specifications are larger. Small size of the pipe must be re-use of stretching process production, and with continuous extrusion method, can directly produce a variety of specifications of small pipe and mini-profiles. Continuous relief refers to the billet (continuous casting billet, drawing or even rolling rod and powder pellets, etc.) continuously avoid the extruder
