本文通过水平连铸全过程钢水和铸坯温度变化及相关参数的实测，研究了水平连铸过程中钢的热平衡规律，并建立了铸坯凝固传热、中间包钢水温度、钢包钢水温度、包衬温度与吸热等数学模型。实测和分析表明，在该铸机上，钢水在钢包和中间包中分别损失了其热量的７％和１．２％，在结晶器和空冷段所传出的热量分别占１８％和２０％，切割时仍有５４％的热量保留在铸坯中。
In this paper, the whole process of horizontal continuous casting of molten steel and slab temperature changes and the relevant parameters measured, the horizontal continuous casting process in the heat balance of the law and the establishment of the slab solidification and heat transfer, tundish molten steel temperature, ladle molten steel Temperature, liner temperature and heat absorption and other mathematical models. Measurements and analyzes show that molten steel lost 7% and 1.2% of its calories in ladle and tundish on the caster and 18% and 20% respectively in the mold and in the air-cooled section, 54% of the heat remains in the slab at the time of cutting.
