摘要
连铸板坯表面质量缺陷主要是纵裂纹和横裂纹,通过其表面缺陷的特征,分析连铸板坯产生表面质量缺陷的原因和影响因素。提出改善钢水和耐材质量,改善设备条件等措施,可以避免连铸板坯表面裂纹的产生。
The surface quality defects of continuous cast slab are mainly transversal and longitudinal cracks.After analyzing the causes and affecting factors for slab surface quality defects through the characteristics of surface defects,the author proposes measures of improving the quality of liquid steel and refractory and equipment conditions,which can prevent slab surface crack from forming.
