| 摘 要： | 通过对梅钢炼钢厂连铸机板坯边裂的现场调查、测试和统计，分析了板坯边裂的成因，并提出了相应的对策，指出结晶器足辊变形、结晶器倒锥度不合适、结晶器内钢水偏流、结晶器角缝挂钢、浸入式水口参数及吹氩操作等是产生连铸板坯边裂的主要原因。

| Abstract: | Edge crack of Continuous Casting Slab in Meigang, Causes edge crack are analyzed, and corresponding Prevention Measures are put forward. It is brought that the main causes edge crack are deforming mould foot roller, improper mould back draughting, biased molten steel inside the mould, molten steel sticking to the mould comer, the parameters of submerged entry nozzle, argon blowing operation and so on. |
