摘　　要：用多元合金元素增加高铬白口铸铁的淬透性,其效果比仅用钼明显好,并且经济。根据铸件的半冷却时间,用广义Dodd计算高铬铸铁的淬透性公式,求出各合金元素含量。据此生产出的铸件,耐磨性能良好。Compared with using only Mo, obviously better effect can be obtained by using multiple alloy elements to increase the hardenability of the high-Cr white cast iron. According to the half-cooling time, contents of every alloy element were determined by adopting the broad sense Dodd-formula for calculating hardenability of the High-Cr white cast iron. The castings produced based on the calculation results have a good wear resisting property.

关 键 词：高铬白口铸铁 半冷却温度 半冷却时间
