摘要
为优化钢包耐火材料,利用ANSYS16.0对钢包壁耐火材料温度分布进行计算。优化设计钢包工作层与永久层耐火材料。结果表明:导热率越低,钢壳表面温度降低的速度越快;工作层导热率从5.0W/(m K)降到3.0W/(m K)时,钢壳表面温度降低4.6%;永久层导热率从0.8W/(m K)降低至0.6W/(m K)时,钢壳表面温度降低7.1%;优化设计后的钢包可减薄50mm,使钢壳温度降至244.412℃,实现钢包热损失少,包壁减薄,增加熔炼钢水,达到"节能减排"的要求。
In order to optimize the refractory materials for ladle,ANSYS16. 0 was used to calculate the temperature distribution of the ladle wall refractory material. The design of working layer and permanent layer refractory material for ladle was optimized. The results show that the lower the thermal conductivity,the faster the surface temperature of the steel shell decreases. When the thermal conductivity of the working layer was reduced from 5. 0 W/（ m K） to 3. 0 W/（ m K）,the surface temperature of the steel shell decreased by 4. 6%. The thermal conductivity of the permanent layer decreased from0. 8 W/（ m K） to 0. 6 W/（ m K）,the surface temperature of the steel shell decreased by 7. 1%. The ladle can be thinned 50 mm and steel shell temperature reduced to 244. 412℃ after optimized design which can reduce the heat loss and the wall thickness of ladle and increase the molten steel to achieve the requirements of energy saving and emission reduction.
