Abstract
PURPOSE: To make possible then production of strip steel plates of superior material quality by providing induction heating furnaces over the run-out tables on the exit side of roughing mills and the inlet side of finishing mills.
CONSTITUTION: The temperatures of the bar are controlled in its lengthwise direction so as to quickly compensate temperature drop components by the induction heating furnaces of heating time constants far shorter than those of heating furnaces, provided to the hot-run tables on the exit side of roughing mills and the inlet side of finishing mills. Namely, the temperature rise components on the inlet side of the finishing mills for compensating the temperature drop components of the exit side temperatures of the finishing mills are obtained by a temperature drop compensation value operating device 3. These and the target temperature on the inlet side of the finishing mills as determined by an induction heating furnace temperature control unit operating device 4 are outputted to an induction heating furnace temperature control unit 6. The most economical extraction temperature is set from the target temperature on the exit side of the roughing mills by a heating furnace extraction temperature operating device 5 and is outputted to the combustion control unit 7 of the heating furnaces.
