摘　　要：利用ANSYS有限元分析软件模拟了在电磁引流系统中用铁粒和碳粉混合物替代传统引流砂时上水口处1,3 h及稳态(时间无限长)的温度场分布,发现Fe/C混合物的温度由上向下逐渐降低,形成一定的温度梯度.在此基础上,验证了Fe/C混合物中的铁粒在一定的工艺参数下可以短时间内熔化,从而实现钢包的顺利出钢.验证了钢包耐火材料在电磁引流过程中可以满足工艺要求.提取了钢包底板的温度场分布,校验了钢包底部钢板在感应加热作用下的安全性.With the mixture of iron particles and carbon powder used instead of the conventional nozzle sand in the electromagnetic steel tapping system,the distribution of temperature field in nozzle upper was simulated for 1,3 h and in steady state（infinite time） by the FEM software ANSYS.It was found that the temperature of the Fe/C mixture decreases gradually from top to bottom,thus forming a certain temperature gradient.Then,it was verified that the iron particles in the mixture can be melted quickly on certain process parameters so as to make sure that the operation of steel tapping from ladle is successful.How the ladle refractory meets the technological requirements in the electromagnetic steel tapping process was discussed.And the safety of the ladle bottom plate under the action of electromagnetic induction heating was checked via the distribution of temperature field on the plate.
