Abstract

PURPOSE:To coincide a sampling temperature of a steel billet with the desired temperature by estimating the outlet temperatures of each zone of the steel billet with the dimension, temperature, sampling pitch of the steel billet and a predetermined fuel input flow rate and controlling a fuel input with the difference from the desired outlet temperature, when a steel billet is heated in a heating furnace comprising a plurality of treating zones. CONSTITUTION:A steel billet is heated in a heating furnace 1 comprising a preheating zone 1a, the first heating zone 1b, the second heating zone 1c and a soaking zone 1d. Predetermined flow rates of fuel input for each zone are obtained from the dimension, predetermined sampling pitch and estimated temperatures of the steel billet. Steel billet sampling temperatures on each zone of the heating furnace are assumed by computation from the calculation of heat balance on the flow rates, dimension, sampling pitch and estimated temperatures of the steel billet. The difference between these temperatures and the desired outlet temperatures on each zone of the steel billet are then assumed by computation with an arithmetic unit 3, and, in order to make this difference small in average and the thermal efficiency optimum, the predetermined flow rates of fuel input on each zone are corrected by a fuel flow rate adjusting equipment 2 according to said difference, resulting in coinciding the sampling temperature of the steel billet with the desired temperature under a high fuel efficiency.
