在铸模内壁全周具有连续水平带状的气体射出口,使气体或空气均一连续地吹出进行连续铸造的一种方法。发明的详细说明铸锭表面通常不是完全平滑的,而是具有凹凸不平或经常出现局部成层缺陷。尤其是连续铸造的铸锭,因与铸模表面摩擦而易产生表面缺陷。为了除去此种表面缺陷,在 A method of continuously casting a gas injection port having a continuous horizontal band of the entire circumference of an inner wall of a mold so that gas or air is continuously and uniformly blown. DETAILED DESCRIPTION OF THE INVENTION The ingot surface is typically not completely smooth, but rather has asperities or often localized delamination defects. In particular, continuous casting ingot, because of friction with the mold surface prone to surface defects. In order to remove such surface defects,
