摘要： PURPOSE:To eliminate the wasteful combustion in a soaking pit by detecting the way of heating in the soaking pit when the steel ingot rapped from the inside of a casting mold is charged thereon and controlling the timing for changing the flow rate for charging fuel in accordance with the heating rate. CONSTITUTION:A thermometer is beforehand provided in a soaking pit so that the heating rate (DELTAT/DELTAt=alpha) in the unit time of the temp. in the furnace is determined. The inside of the soaking pit is first heated up only by the radiation heat of the steel ingot without combustion therein in the stage of charging the steel ingot into the pit. Since a difference between the temp. of the ingot and the temp. in the pit is large in this case, the heating rate alpha in the pit attains a large value in the initial period of heating in the pit but the rate alpha of the heating rate in the pit decreases in he late period. Fuelis burned at a supply rate G1 when the value alpha decreases lower than a target value alpha2 and while the heating the heating rate alpha in the furnace is again measured, the flow rate of the fuel is increased to G2 at the point of the time when the next target value alpha2 is attained. The fuel is burned at the fuel flow increased equally stepwise in the above-mentioned way. The combustion is thereafter stopped when the temp. in the furnace attains finally the prescribed max. temp. and the steel ingot is discharged from the holding furnace.

摘要： PURPOSE:To attain to conserve the unit product of fuel by a method wherein fuel throwing in a time when a steel ingot is baked up is stopped at a time when a temp. set time in a furnace is elapsed for a predetermined time and, thereafter, the steel ingot is heated by a holding heat of a furnace body. CONSTITUTION:Before the temp. set time in the furnace is reached to t2' from t1', at a time of t'', throwing of a heavy oil is stopped and, thereafter, the steel ingot is heated by holding heat of the furnace body. In this case, the temp. in the furnace is lowered to Pe from P2'' in a temp. curve 1'' in the furnace but, because said temp. Pe is higher than an objective surface temp. S of the steel ingot, the steel ingot can be heated by the holding heat thereof. Then, a gradient of a surface temp. curve 2'' of the steel ingot in this case becomes slow and a heat holding time is lengthen to te from t2' in accordance therewith but a flow amount curve 3'' of the heavy oil moves to t2'' from t2'. As the result, heat holding time of the steel ingot becomes long but a fuel unit product can be conserved.
