Abstract Computational accuracy of heating process mathematical model based on total heat exchange factor (THEF) method was found easy to decrease due to complex heat exchange process in a furnace. To solve this problem, an experimental correction method of dynamic compensation of THEF was therefore proposed on the basis of establishing steel heating process mathematical model. Temperatures of steel at different positions were measured by dragging coupling method. Then the corresponding THEFs can be achieved, and they were compared with those from model computation to determine the compensation values of THEF. Simulation results show that steel temperatures from the proposed model approaches experimental data and the experimental correction method meets the requirement of accuracy for online and real-time control in steel heating process.
