Zusammenfassung:PURPOSE:To prevent the development of triangular defect as the quality defect in a twin belt continuous casting method. CONSTITUTION:A molten metal dipping part of a casting nozzle 1 used in the twin belt continuous casting method is heated at the temp. from lower than the m.p. of molten steel to this m.p. -500 deg.C, and the casting is started and further, this part temp. is raised to the m.p. of the molten steel or higher during casting. By this method, solidification and stickness of the molten steel at the meniscus between the belts and the casting nozzle are perfectly prevented, and the development of the triangular defect can be prevented.
