shell thinning(① Shell thinning occurs when the solidified shell is partially remelted as the flow of molten steel washes the solidification front 当钢水冲刷凝固前沿导致凝固坯壳部分重新熔化时，坯壳就减薄了。② Shell thinning is usually localized around the breakout hole. 坯壳减薄通常仅限于环绕漏钢口的周边。)
thin shell type breakout(【技】由于结晶器内钢液温度过高、传热不良、或冷却强度低等原因造成坯壳过薄，铸坯出结晶器后抵抗不住钢水静压力而引发的漏钢。: The addition of a low heat removal alarm has significantly reduced the number of thin shell type breakouts. 增加了散热下限警报器后，薄坯壳型漏钢次数大幅度降低。)
