摘要： 为了将电磁出钢系统应用于实际生产，提出一种能让该系统使用的感应加热线圈在高温水口砖内正常工作的隔热方法.利用数值模拟方法考察了300t电磁出钢系统用钢包水口座砖的热流密度以及有无隔热层条件下置入在水口座砖内的感应加热线圈的工况温度.结果表明，无隔热层条件下线圈在高温水口座砖内无法使用，而在线圈的顶部及内外两侧布置一层隔热材料可以有效地降低线圈的工况温度；隔热层的厚度和导热系数均影响线圈的工况温度，当隔热层厚度为40mm，导热系数为003W/(m·℃)时，线圈的最高工况温度由原来的1187℃降至467℃，满足线圈的工况温度要求.

Abstract: In order to apply the electromagnetic induction controlled automatic steelteeming system in production， a new insulating method which can ensure the normal operation of the induction coil used in the system in hightemperature nozzle brick was proposed. The numerical simulation method was employed to investigate the heat flux of the nozzle brick used in 300t ladle of the electromagnetic steelteeming system and the working temperature of the induction coil implanted in the high temperature nozzle brick with and without the insulating layers. The results showed that the induction coil was not suitable using in high temperature nozzle brick without the insulating layers， while the induction coil working temperature decreased with the insulating layers on the top and both sides of the induction coils. The thickness and the conductivity of the insulating layer both affected the coil working temperature. The coil working temperature decreased from 1187℃ to 467℃ at the condition of the thickness 40mm， the conductivity 003W/(m·℃) and met the coil working demands.
