In the process of cold rolling production, roll shape is a very important parameter. Both the disturbance variables and control variables are existing in the control system that influencing the quality of the strip shape directly. How to predict the thermal crown of the roll is crucial to the control system of the whole set. According to the real data, we set the boundary conditions and the heat transfer coefficient using ANSYS software for large finite element analysis that considering all the affecting factors. We get the temperature spread field and the thermal expansion results of different states after simulation and calculation: in steady state, the highest temperature of the central zone on the surface is about 65 \(^{\circ }\)C, the biggest expansion is about 174 \({\upmu }{\mathrm{m}}\) which are close to the actual data. We can carry on the subsection control of the cooling system according to the temperature and expansion based on the model to reduce the influence and improve quality of strip shape.
