这种铸造工艺不是将熔融金属浇入铸型。相反地,是将铸型浸到液体金属中去。发动机和其他往复式机械所用的铸铁活塞环有两种不同的制造方法。其一为:先用静力浇铸法或离心浇铸法铸出“筒子”,再在初车和镗孔后继续加工的过程中切出单个活塞环。另一为:单个地铸出每一个活塞环毛坯,先磨削侧面,再继续进行其他加工。后一种浇铸法是下述发展的研究对象,简称之“单铸法”。单体铸造法采用湿型叠箱串铸工艺,每
This casting process does not pour molten metal into the mold. Instead, the mold is immersed in the liquid metal. There are two different manufacturing methods for cast iron piston rings used in engines and other reciprocating machinery. One is to first cast the “cheese” using a static casting method or a centrifugal casting method, and then cut a single piston ring during the initial drilling and boring to continue machining. The other is to cast each piston ring blank individually, grind the sides first, then continue with the other machining. The latter casting method is the development of the following research object, referred to as the “single casting method.” Monomer casting method using wet-type stacker string casting process, each
