Base on measured data provided by Baosteel, thermal boundary condition parame-ters in the hot rolling process were reversely determined. Using such parameters, the preci-sion of numerical analytical results was improved. As an application, the temperature and rolling stress in each pass of hot rolling process were predicted. The simulation results showed good coincidence with the industrial measured data.
