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.

Key words： hot metal ladle mode; ladle preparation; cost; continuous casting heats; calculation model
