METHOD OF HEATING CONTROL AND HEATING CONTROL APPARATUS FOR CONTINUOUS HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a method of heating control and a heating control apparatus of a continuous heating furnace of which reset processing of heating condition can be performed more adequately. SOLUTION: In a continuous heating furnace 10 having a plurality of heating zones Zi, line speed S is controlled by a target line speed OS calculated from the weighted average of the quasi-optimum line speed SSi calculated based on the inside furnace temperature Tgi at a plurality of the heating zones Zi.
