Abstract

PURPOSE:To decrease the danger of breakout and to perform lubrication smoothly by providing fine grooves in a large number of steps in a longitudinal or transverse direction or in both directions at intervals below specific values on the inside surfaces of a mold. CONSTITUTION:A large number of steps of, for example, longitudinal grooves 8, 8', 8'' are provided on the inside surfaces of a mold 1 of a continuous casting device using gaseous lubrication, and a large number of gas ejection holes 3, 3' are provided in the lowermost step. The intervals of the grooves are set at <=2X10<-3>m. When a constant flow rate of gases are ejected from the holes 3, 3' into the mold, the flow resistance in the transverse direction of the gaseous flow lowers because there are the grooves 8, 8', 8''. The flow resistance of the gases is increased in the longitudinal direction of the mold 1 by the orifice effect in the parts of the edges of the grooves 8, 8', 8''.
