高铬铸铁在泥浆泵叶轮上的应用

Study on the slurry Pump s Paddle Wheel Made of High Chromium Cast Iron

首先对高铬铸铁泥浆泵叶轮的铸造工艺和热处理工艺进行了研究，并对其耐磨性和冲击韧性进行了试验测试，从化学成分。

The casting process and heat treatment of slurry pump s paddle wheel made of high chromium cast iron have been studied and the wear resistence and impact toughness of the cast iron have been tested. The examning results of the chemical composition,microstructure and mechanical properties have shown that it is feasible to make slurry pump s paddle wheel of high chromium cast iron.
