Abstract
PURPOSE:To reduce the consumption of fuel to the minimum and to carry out stable temperature control, by controlling the temperature of the atmosphere in the furnace at every steel billet by estimating the temperature distribution inside the steel billet at every steel billet from the temperature of the atmosphere inside the heating furnace and the dimensions of the material, etc. CONSTITUTION:The position of the steel billets 5 charged succesively into the heating furnace 8 is recognized with the tracking device 1 and is stored in the memory device 6. The temperature of the atmosphere in the furnace at each zone of the heating furnace 8 is measured with the temperature measuring device 3 through the thermocouples 4. On the basis of the measured position of the steel billet, the temperature of the atmosphere in the furnace and the temperature of the steel billet situated next, etc., the amount of change of the temperature distribution inside each of the steel billets 5 from the estimated value of the preceding time is calculated periodically with the temperature controller 2 and the temperature distribution which has been estimated at this time is stored in the memory device 6. By prestimating the temperature change of each steel billet on the basis of this estimated temperature distribution of each steel billet, it is checked that all of each steel billet in the furnace satify the heating condition or not.
