湿型砂铸造高性能TR905球铁曲轴

Green Sand Casting High Performance TR905 Ductile Iron Crankshaft

基于湿型砂铸造生产线,主要以废钢为原料,采用电炉熔化,熔化过程中加入碳化硅基复合预处理变质剂,稳定生产出本体抗拉强度900 MPa,伸长率5%以上的发动机球铁曲轴,代替原锻钢曲轴,大幅降低了生产成本。

Based on the green sand casting production line,the waste steel is used as main raw materials which was melted by electric furnace.The silicon carbide-based composite pretreatment modifier was added during the melting process.The results show that the ductile iron crankshaft of the engine with the tensile strength of 900 MPa and the elongation rate of more than 5%can be produced statically.Replace the original forged steel crankshaft,greatly reduce the production cost.
