Outline
The process of rolling the TC4 titanium alloy tube blank with the PQF rolling mill, Accu rolling mill and Assel rolling mill was simulated by ABAQUS simulation software as well as the changes of section form, temperature, stress and strain in rolling process were analyzed. The results showed that the change of section form in the process of rolling TC4 seamless tube with PQF rolling mill was smaller than that in the process of rolling TC4 seamless tube with Accu and Assel rolling mills as well as the dimension precision was higher; the stress distribution in the rolling process with Accu and Assel rolling mills was more complicated than that in the rolling process with PQF rolling mill; the metal strain of inside wall thickness was larger than that of outside wall thickness when the three rolling routes were adopted; the temperature reduction with Accu and Assel rolling mills was smaller than that with PQF rolling mill because of the short rolling time.
