摘要：
By establishing finite element mathematical model for heat transfer in the ladle to simulate transient temperature distribution field, this paper, with typical value method and energy conservation method, studies effect of ladle preheating temperature and insular linings of the ladle on molten steel temperature drop in the 210 t ladle used by Chongqing Iron & steel Co., Ltd. Furthermore, decrease rate of molten steel temperature is forecasted under different working conditions. These predicted results are compared to those obtained by temperature measurements on the site, which shows that ladle preheating temperature affects the rate of molten steel temperature drop a lot, and the decrease rate of molten steel temperature in casting state is greater than in holding state of molten steel. Actual temperature decrease rate of molten steel on the site is between one obtained by energy conservation method and one obtained by typical value method. These studied conclusions provide good reference for molten steel temperature control in Chongqing Iron & Steel Co, Ltd.
