摘　　要：小方坯角部纵裂漏钢的根本原因就是因为在铸坯角部产生剪切应力所造成的,而铸坯厚度不均匀程度越大角部剪切应力就越大,影响铸坯坯壳厚度生长不均匀的因素包括:结晶器尺寸、结晶器振动、二冷冷却和工艺因素等。我厂根据不同的原因进行详细的分析并制定出了相应的措施,从根本上解决了小方坯角部纵裂漏钢的问题。The small billet comer because the root cause of longitudinal crack of steel leakage caused by the shear stress in slab comer, and slab thickness is not uniform, the greater the degree of Angle shear stress affect the casting billet shell thickness uneven growth factors include mold size, mold vibration, two cold but and technological factors, etc. Our factory according to the different reasons for a detailed analysis of and work out the corresponding measures to fundamentally solve the small billet Angle and longitudinal crack of steel leakage problem.
