摘　　要：利用ANSYS模拟软件,通过瞬态热分析获得了新、旧渣罐和其内熔渣冷却过程的温度分布及其变化规律。结果表明新渣罐具有更加优异的冷却效果和热疲劳强度。相比于旧渣罐,冷却3 h后新渣罐温度更低,其内熔渣温度降低也更快。这表明新型渣罐使用6个隔板分成6个型腔的结构设计有利于提高其热疲劳强度和钢渣的后续处理。此外,热与结构耦合分析结果表明,新、旧渣罐的热应力均能满足高温强度使用要求。The distribution and change rule of the temperature of the new,old slag pots and the slag stored inside during cooling process were obtained by transient thermal analysis using ANSYS simulation software.The results show that the new slag pot has better cooling effect and thermal fatigue strength.Compared with those of the old pot tank,the temperature of the new slag pot is lower after 3 h cooling,and the slag temperature in the pots decreases faster.This indicates that the structure design of the new slag pot in which six partitions are used to divide the old slag pot into six cavities can better improve thermal fatigue strength and subsequent treatment of steel slag.In addition,the coupling analysis of heat and structure shows that the thermal stress of both the new and old slag pots can meet the requirements of high temperature strength.
