Abstract：

Grain refinement is the most important and the most basic method to control the structure of metal materials.Using software Deform, the forging process of large marine shaft forgings was simulated, and through changing forging method, the change trend of grain refinement was analyzed.The results show that with the increase of overlapping length,the grain size decreases; with the increase of forging percentage,the grain size decreases first and then increases, when forging percentage is 12.5%, the grain size is almost the smallest. So the grain refinement can be promoted effectively and the forging quality can be improved by improving forging technology for large forgings.
