摘要: 以综合成本最优为目标,分别建立转炉热源充足及热源平衡(欠热)两种情况下的经济连浇炉数计算模型,经济连浇炉数为由铁水包备包造成的成本损失与中间包耐材损失、钢水收得率成本损失之和相减,综合成本损失最小的连浇炉数. 应用该模型,以重钢新区2#连铸机SPHC钢种为案例进行计算,转炉热源富余和热源平衡(欠热)情况下的经济连浇炉数分别为16和15炉.

Abstract: Calculation model of economical continuous casting heats both in the case of the sufficient and balanced (inadequate) heat supply for BOF was established respectively with the objective of the optimal comprehensive cost. The minimum cost losses could be obtained when the cost losses due to ladle preparation was subtracted from that of the sum of the refractory of the tundish and the molten steel recovery rate. Selecting the steel grade SPHC of No.2 caster in Chongqing Iron & Steel Co., Ltd. as investigation case, the model is applied to calculate the economical continuous casting heats, whose result are 16 and 15 with the sufficient and balanced (inadequate) converter heat supply, respectively.
