摘要
针对板坯投产以来易出现表面纵向裂纹的情况,结合现场实际生产特点,从钢水质量、工艺控制和操作等方面进行分析与改进,铸坯表面纵向裂纹发生率得到了有效控制,板坯表面纵裂发生率由2009年的6.2%降到2010年的3.5%。
In light of problem of the longitudinal cracks frequently occurring on the surface of the slab since commissioning analysis and improvements have been carried involving the liquid steel quality, processing control and operation. As the results the occurrence rate of the longi- tudinal crack on the surface of the slab has been effectively controlled and the occurrence rate of the crack has been reduced to 3.5 %in 2010 from 6. 2 % in 2009.
