【Abstract】 The main factors that influence the stability of aluminium tube drawing with a floating plug (lubricant, plug taper angle, and drawing velocity) are optimized by orthogonal trial method. In addition, the reasons of influence the stability are analysed in detail. At last, the paper provided basis for working out the optimal process.更多还原
