AbstractThe present invention provides a sucessive electric slag fusion casting process for making crank blank. It is implemented by slag remelting process and slag fusion casting process, and is characterized by that it adopts slag remelting process to manufacture crank head, crank tail and crankpin of crank casting, and adopts the fusion casting process to make said castings and crank arm sucessively fusion-casting together, and make them fused into one-body structure. Said invention is simple in technological process, its technological parameters are stable, can effectively solves the defects of poor moldability, crack and slag inclusion, etc.. As compared with similar product it possesses the advantages of good mechanical property and low production cost, etc..
