Abstract

PURPOSE: To detect the in-furnace residence time of charging materials and control a heating furnace stably and satisfactorily by providing an arithmetic device which forecasts the extraction pitch of a charging material and a charging material just before the same according to the rolling schedules for both materials.
CONSTITUTION: The rolling schedule after a charging material is extracted from a heating furnace 6 is operated with the 1st arithmetic device 1. From this rolling schedule and the rolling schedule of the charging material just before the same stored in a memory device 3, the extraction pitches of both materials are forecast with the 2nd arithmetic device 2. In accordance with the operated extraction pitches, the in-furnace residence time of the charging material is forecast with an arithmetic device 4. In accordance with the forecast in-furnace resistance time, the flow rate of the fuel to be supplied to the furnace 6 and the setting of furnace temp. and the like are controlled with a control device 5.
