Numerical Simulation of Seamless Tube’s Stretch Reducing Process

摘要：

The stretch reducing process is the last hot deformation process of the hot-rolled seamless steel tubes production. Its role is to decrease the tubes diameter under the large tension and expand the range of product specifications. But the stretch reducing process often results in wall thickness tolerance at the head and end of the tube. In order to solve the problem, a 3D elastic-plastic finite element analysis model was established to simulate the stretch reducing process of Φ 159 unit. Based on this, the tubes wall thickness distribution was studied and the parameters of sharpen rolling process was put forward. Numerical simulation results indicate that with the parameters of sharpen rolling process, the length of wall thickness tolerance was shorten and the rate of finished products was proved.
