The present invention relates to a temperature control method for a heating furnace. According to the present invention, a temperature profile of the inlet of a roughing mill is calculated, after setting a temperature profile of the outlet of the roughing mill, to stabilize the temperature of the rolled material measured at the inlet of the rolling finishing mill. Based on the profile of the temperature of the inlet of the roughing mill, the soaking zone temperature of the heating furnace is calculated to control the furnace temperature. Thereby, threading in the rolling finishing mill can be improved.
