| Abstract: | Rare earth chrome-manganese-silicon alloy and silicon-calcium-manganese alloy were developed to effectively solve the problems of difficult fusion and severe slagging tendency caosed by the rare earth and calcium in gray iron. The effect of rare earth and calcium on the structure and property of gray iron were analysed in detail through laboratory tests and production technology tests. It is proposed rare earth chrome-manganese-silicon alloy can replace the costly rare earth ferro-molybdenum alloy to produce diesel engine cylinder with high property. |
