汽车、摩托车的配件———活塞环 ,其毛坯通常采用合金铸铁通过砂型铸造的方法来获得 ,铸造毛坯的最大缺陷是表面砂气孔不易控制 ,且铸造活塞环的过程中 ,产生大量的只能作为回炉料的浇冒口。基于以上原因 ,我们提出了钢质活塞环（图１）。１钢质活塞环加工钢质活塞环的工艺流? Automobile and motorcycle parts --- piston ring, the rough is usually cast by the way of the alloy cast iron sand to get the biggest drawback of casting rough surface sand holes is not easy to control, and the process of casting piston rings, resulting in a large number of Can be used as a refueling riser. For the above reasons, we propose a steel piston ring (Figure 1). 1 steel piston ring processing steel piston ring process?
