Abstract：

For the performance of the serious work-hardening and large deformation resistance at room temperature of stainless steel tube 304, the experimental research was carried out to explore hot power spinning forming regulation of stainless steel 304. The spinning experiments with three steps and 60% total thinning ratio were carried out by HGQX-LS vertical hot power spinning machine under the molybdenum disulfide lubricant and the high frequency electromagnetic induction heating. The influences of the forming temperature of the tubular blank and the feed rate of the roller on the forming qualities of spun workpiece were analyzed based on the experiment. The results show that hot power spinning is one of the most effective methods in manufacturing stainless steel tubes 304, and the high quality spun workpiece can be obtained under the heating temperature of the tubular blank 1000 ℃ and the feed rate of the roller 0.4 mm·r-1.
