A continuous casting method in which an 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.
A nozzle heating device which heats an outside surface of a continuous casting nozzle for supplying molten metal into a mold while immersed in the molten metal in the mold to 1000° C. or higher, the nozzle heating device comprising:
- an insulator provided so as to surround the outside of the continuous casting nozzle leaving a gap;
- and
- an external heater which performs radiant heating, provided on an inside surface of the insulator facing the continuous casting nozzle.
