摘　　要：本文通过对传统弯锻工艺的数值模拟并在此基础上改进，结合特殊的热处理工艺，研制出了性能完全满足要求的船用曲拐，并有效解决了传统弯锻过程中容易出现的缺陷。A study of the large crank＇ s advanced bend forging process is made in the paper by means of numerical simulation. Combining with the heat treatment process the qualified marine crankthrow was developed without forging defect during tradition bend forging process.
