Abstract: To avoid the serious ladle damage caused by inappropriate baking,a numerical model for ladle baking was constructed with the numerical simulation method.The temperature distributions of refractory linings of high alumina bricks,alumina magnesia carbon bricks and magnesia carbon bricks,respectively, during baking were studied.The results show that the temperatures of magnesia carbon bricks are 20 -30 ℃and 50-60 ℃higher than those of the alumina magnesia carbon bricks and high alumina bricks after the baking tend to be stable within 18 h,respectively.The maximum and minimum temperature difference of different positions in the same material lining for high alumina,alumina magnesia carbon and magnesia carbon bricks is 197.4 ℃,140.6 ℃ and 133.3 ℃,respectively.The magnesia carbon bricks perform the best on the heating capacity and the lining temperature uniformity.
