Abstract

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.
