Zusammenfassung:	PURPOSE:To execute the uniform treatment to a material to be treated and to improve the durability. CONSTITUTION:In a bell type coil annealing furnace provided with plural stages of burners 7a-7c in the height direction, based on the temp. near a bottom convector 3a, the total combustion of the burners is controlled and also, by making the combustion quantity of the burner at the lowest stage the max., the combustion of the bell type annealing furnace is executed.
