Abstract：
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.
