Abstract：Using imaginary surface method，a twodimensional mathematical model for slabs heating process in radiant tube rollerhearth treatment furnace was established and the model control system of rollerhearth heat treatment furnace was developed. The model included the slab temperature tracking and calculation of furnace temperature setting. The model of slab temperature tracking can calculate the slab temperature in the furnace，which can provide the basis for the slab preservation in heat treatment. The furnace temperature setting model can calculate the setting range of furnace temperature for different steel grade，different thickness and different aim temperature of heat treatment，which can guide producing. This model was successfully applied in a radiant tube rollerhearth heat treatment furnace in a certain iron and steel company，and it was checked by buried thermocouple test. Results showed that the accuracy of the model was within ±5 ℃ and the control effect was good.
