ＺＱＳｎ１２－２作为一种新型的锡青铜材料，现已被广泛应用于减速传动机械的轮缘制作，本文结合近十年在生产实际中对ＺＱＳｎ１２－２合金的熔炼，离心铸造工艺的探索，制定出已为生产实践证明是比较成功的ＺＱＳｎ１２－２合金的离心铸造工艺
As a new type of tin bronze material, ZQSn12-2 has been widely applied to the rim production of deceleration transmission machinery. Based on the exploration of the production and practice of ZQSn12-2 alloy melting and centrifugal casting in recent ten years, ZQSn12-2 is formulated Centrifugal casting process of ZQSn12-2 alloy which has been proven successful in production
