off-corner(The characteristic of the slag entrapment breakout is that a breakout hole generally occurs in corner or off-corner positions. 夹渣漏钢的特点是漏钢口一般出现在坯角或偏离坯角的位置。)
longitudinal off-corner subsurface crack(Longitudinal off-corner subsurface cracks are predicted to form more easily in small-corner-radius billets. 人们预测,偏离角皮下纵裂纹更容易形成于小圆角半径的小方坯中。)
