摘要
结合重庆钢铁股份有限公司炼钢厂的现状,对矩形坯脱方、凹陷、鼓肚及中间裂纹等质量缺陷的成因进行分析,发现铜管状况与钢种、拉速不匹配,铸坯不均匀冷却是铸坯质量缺陷形成的主要原因,并制定了相应的预防及优化措施,实施效果良好。
Combined with the current situation of Chongqing Iron and Steel Co. , Ltd. , the reasons for rhombic, sag, bulging and inner crack of rectangular billet are analyzed and found that the primary cause to the quality defect is that the copper tube of the mould does not match with the steel grade and the casting speed. Thereby preventative and optimization measures are set up and the practical results are desirable.
