摘要
针对柳钢生产电极扁钢时存在的表面裂纹缺陷,利用低倍、金相及扫描等手段进行分析,结果表明:产生轧后裂纹的主要原因是铸坯脱氧不良及m(Mn)/m(S)低。介绍实施了的加深脱氧深度和提高m(Mn)/m(S)等改进措施及效果。
The surface cracks occurred on the electrode flat steel of Liuzhou Steel were analyzed by using macro check,metallographic analysis and scanning,and the results showed that：cracks occurred after rolling were caused by bad deoxidization of strand and low m（Mn）/m（S） mainly.The countermeasures to increase deoxidization degree and improve m（Mn）/m（S）,and its effects were introduce.
