向下运动的坯壳(In a sticker breakout, a portion of the strand shell in the vicinity of the liquid level adheres to the mold wall and separates from the downward-moving shell. 粘接漏钢时,钢水面附近的一部分坯壳粘结到结晶器壁上,随后即与向下运动的坯壳断开。)
流钢孔向下角度(浸人式水口的: The submerged entry nozzle is a conventional dual rectangular port design with downward port angles of 15 degrees. 该浸人式水口系普通双矩形流钢孔结构,流钢孔下倾角为15。。)
结晶器向下运动速度(A negative strip occurs when the downward velocity of the mold during each cycle exceeds the withdrawal speed of the strand. 在每一振动周期内,当结晶器向下运动的速度超过拉坯速度时即出现负滑脱。)
