PROBLEM TO BE SOLVED: To provide a method for restraining the adverse effect due to a high temperature on a wall refractory in a furnace to the minimum limit in a refining method by controlling the surface temperature of the refractory and/or the temperature in a space part for preventing the sticking of skull. SOLUTION: A material 1 having high heat conductivity is buried into the refractory for the furnace wall, and further, according to the temperature and/or rising/lowering speed of the temperature measured with a thermocouple 3 disposed in the inner part of this material 1, the secondary combustion ratio in the furnace or the firing power of a fuel burner is controlled.
