Abstract：

The calculation and forming process of rolling-pass optimization were completed by using computer aided software. Simulation methods of change for temperature field and stress-strain field when rolling were established by using deform-3D. Temperature control level of temperature diffusion time on temperature fluctuation in control rolling technology was predicted by using computer simulation，at the same time, the influence analysis of different lubrication conditions on concentration of rolling deformation was completed. Finally, the control level of deformation homogeneity for passes and control capacity of performance stability by using control rolling technology after optimization were verified through actual rolling experiment. The results show that rolled pieces have uniform regional organization, strength variance between all rolling experiment titanium bars is less than 20 MPa，which realizes the targets of pass optimization and improvement of rolling stability by rolling control.
