- 摘要:
- 往复式压缩机缸体铸件具有复杂的水腔和气腔纵横交错,零件结构比较复杂。传统的冒口一般为环形冒口,很少使用无冒口工艺。往复式压缩机缸体材质为QT450-10A,重量4 600 Kg,采用合适的浇注温度和化学成分,局部热节处配合使用冷铁,实现了无冒口工艺。The cylinder casting of reciprocating compressor had complicated water cavity and crisscrossing air cavity,and the part structure was quite complex.The traditional riser was usually annular riser,and riser-free processes were rarely used.The reciprocating compressor cylinder is made of QT450-10 A with a weight of 4 600 Kg.Adopting suitable pouring temperature and chemical composition,the chillers are used at local hot spots to realize the non-riser process.
