A method for heating a nozzle tip during molten drag casting process is provided to manufacture strips continuously and stably and improving Fe-based or Ni-based alloy with high surface quality. A method for heating a nozzle tip during molten drag casting process includes a nozzle preheating plate(6) for transmitting heat to a front end part of a nozzle in a melt drag casting apparatus, torches(7) for heating the nozzle preheating plate at an immediately upper part of the nozzle preheating plate, and a flame reflection plate(8) positioned between the torches and the nozzle preheating plate and having flame passing holes(9). |
