The temperature gradient rolling (GTR) method effectively improves the problem of uneven deformation of surface and core in the rolling of extra-thick plate. Different from the traditional near uniform temperature rolling (UTR) process, there is a large temperature gradient in the thickness direction of the rolled piece during the GTR process, and the rolling force prediction model of uniform temperature rolling cannot be directly applied. Rolling force prediction model is one of the important process control models of plate mill and the basis of plate thickness control. However, there is few research for the method of rolling force predicting during GTR. In order to predict the change of stopping force in GTR process and control the rolling process better, the current paper proposed a simplified method based on the deformation resistance model, fitting of temperature distribution, differential method, and loop iteration. The precision of the method was examined by using a finite element model and plane strain experiment. The mean error between the method and FEM was less than 5%.

Grain refinement caused by deformed austenite recrystallization is an important way to enhance the property of ultra‐heavy plates during hot rolling process. In the present study, with the model coupled microstructure evolution based on Abaqus secondary development, numerical simulation of hot rolling process with different rolling parameters is carried out. The calculation result showed that gradient temperature rolling process can increase the accumulated strain in the center of plate so that 4.9–11.8 µm smaller grains can be obtained. Compared with the microscopic scale numerical simulation for grain nucleation and growth, the model above can accomplish the microstructure evolution simulation of steel plates during rolling process on macroscopic scale. The prediction of grain size can be achieved with the calculation result, which assists engineers in formulating steel plates rolling schedules.
