摘　　要：小方坯脱方是方坯连铸常见的形状缺陷,其成因是结晶器内各边冷却不均匀,致使四个边凝固壳厚度不同而造成。本文从工艺和设备两方面分析小方坯脱方,并介绍相应的防止措施。The off-squane of CC billet is a common formal defect. It is caused mainly by irregular cooling on the various sides of billet CC mould, which makes the shell on the four sides different in thickness. This paper analyses the defect from process and equipment, and also puts porward some proper measures.
