CONTINUOUS CASTING METHOD AND NOZZLE HEATING DEVICE

摘要

In a continuous casting method, the outside surface of a continuous casting nozzle which supplies molten metal into a mold while immersed in the molten metal in the mold, is heated to 1000°C or higher by a nozzle heating device comprising an external heater which performs radiant heating, while the molten metal passes through the continuous casting nozzle. The nozzle heating device has an insulator which surrounds an outside of the continuous casting nozzle while leaving a gap therebetween, and the insulator has the external heater disposed therein and the insulator comprises multiple divided segments.
