Abstract
PURPOSE:To carry out soaking condition controlling in a minimum of soaking zone empty time of soaking pit by correcting the heating zone set temp. to the soaking zone entrance time temp. with respect to the next steel material charged into the furnace till the time of the final steel material of the previous lot is extracted from the soaking zone. CONSTITUTION:The final material of the previous lot is charged at the time t0, enters the soaking zone at the time t1 and is extracted at the time t3. The leading material of the next lot is charged at the time t2 after the time t2 of the final material of the previous lot entered the soaking zone, enters the soaking zone at the time t4 and is extracted therefrom at the time t5. The next lot materials to be charged after the time t4 have no problem because the heating zone set temp. and cycle time have assumed predetermined values. The cycle time changing is accomplished at the time t4, and since the steel materials charged between the time t2-t4 have been heated in the cycle time of the previous lot, the target soaking zone entrance temp. of the next lot is not obtainable. Hence, the combustion controlling of the heating zone and soaking zone is so carried out that the target soaking temp. is obtained.
