摘　　要：为了研究包衬侵蚀对钢水温降的影响规律,通过ANSYS有限元软件以及ParaMesh网格随移技术建立了考虑包衬侵蚀的钢包传热计算模型,研究并分析了包衬侵蚀对包衬及钢水温度的影响规律。结果表明,包衬侵蚀对包衬温度影响较大,在相邻两个修包周期内,包衬侵蚀造成渣线和包壁的包衬内部(工作层与永久层交界处)温差为14~114K;包衬侵蚀导致包壳外表面温度升高,包壳向外散热增加,与此同时,包衬受侵蚀变薄,蓄热减少,两者同时作用导致包衬侵蚀对钢水温降影响不大,最高不超过1K,在实际生产中可以适当地忽略钢包侵蚀对钢水温降的影响。In order to study the influence of ladle lining erosion on the liquid steel temperature drop,a heat transfer calculation model considering the lining erosion was established by using ANSYS finite element software and ParaMesh mesh migration technology.The effect of lining erosion on the lining and molten steel temperature were studied and analyzed.The results showed that the ladle lining erosion had a great influence on the ladle lining temperature.In the next two repair cycles,the temperature difference between the slag line and the wall of the ladle lining internal(the junction of working layer and permanent layer)caused by the ladle lining erosion was about 14-114 K.The ladle lining erosion led to the increase of the outer surface temperature of the cladding,and the increase of the outer heat dissipation of the cladding.At the same time,the lining was eroded and thinned,and the heat storage was reduced.Thus,the ladle lining erosion had a little influence on the liquid steel temperature drop,the maximum temperature drop was no more than 1 K.In the actual production,the influence of the ladle lining erosion on the liquid steel temperature drop can be properly ignored.
