Abstract

PURPOSE:To prevent sticking of an adhesive material to inner wall by using the specific composition of calcium zirconate and the specific quantity of graphite to a nozzle for continuous casting. CONSTITUTION:The nozzle for continuous casting is formed by composition containing 60-90wt.% calcium zirconate, in which contains 40-55% CaO by mol. ratio, and 10-40wt.% graphite. By this method, for example, in the continuous casting for aluminum killed steel, calcia contained in the nozzle is reacted with the alumina, and changed into the compound having melting point lower than the cast molten steel temp. and comes to melt. By this method, the sticking of the alumina to the inner wall of the nozzle is prevented.
