摘要
生产实践发现由于造型冷却条件的限制,采用潮模砂生产铸态QT700-2牌号产品存在机械性能不达标的情况。通过调整化学成分,采用喂丝球化法、强化孕育等手段,实现了铸态QT700-2铸件稳定生产。
Due to the limitation of molding cooling conditions,the mechanical properties of QT700-2 castings produced by green sand molding are not up to standard.Casting QT700-2 can be produced stably by adjusting chemical composition,adopting alloying method,wire feeding spheroidizing method and strengthening inoculation.
