Effect of Wall Thickness of the Billet on 1Cr18Ni9 Stainless Steel Tube Stagger Spinning Process

Abstract

The stagger spinning process of 1Cr18Ni9 tube was investigated by using finite element method. The metal flow rule around the roller during the tube stagger spinning was analyzed. The influences of wall thickness of the billet on effective stress and spinning force were studied using software Deform. The simulated results indicate that the proper wall thickness of the billet should be 8~15 mm, for the billet with length of 100mm and inner diameter of 200mm.
