Effect of Rolling Speed on Instantaneous Temperature Distribution and Thermal Expansion of Work Roll in Hot Strip Rolling

Article Preview

Abstract:

In the unsteady state, work roll temperature distribution and thermal expansion have an enormous effect on the process of hot rolling. The rolling speed in the finish rolling as an important rolling parameter plays a crucial role of obtaining the optimum temperature distribution and thermal expansion. Using the finite element method, it solves the regularity of temperature distribution and thermal expansion with thermal-structural coupling analysis, which provide theoretic proof of optimizing gauge and profile control.
