珠光体基体球铁活塞的生产控制

Production control of pearlite ductile iron piston

介绍了珠光体基体球铁活塞的生产控制,通过合理选择球墨铸铁的化学成分,严格控制球墨铸铁的球化过程,在确保球化良好的基础上,确定了符合生产实际的热处理工艺,以获得高强度、高韧性的珠光体基体球铸铁。并采用有效的检测、控制手段来确保生产的可行性和稳定性。

The production confrol of pearlite ductile iron piston was described.By correctly controlling the chemical composition of ductile iron piston and strictly controlling the process of spheroidization,the heat treatmenf process which can meet the real production needs was decided,in order to obtain the pearlite ductile iron with high strength and high toughness.The effective detection and control methods are used to ensure the production feasibility and stability.
