摘要
针对凌源钢铁股份有限公司炼钢厂方坯连铸生产过程中出现的脱方、渣沟、凹陷等表面缺陷进行了跟踪轧制,根据取样检验结果分析了缺陷产生的原因。采取了优化结晶器铜管倒锥度、优化配水、优化保护渣性能等相应的措施后,上述缺陷得到了有效解决,提高了连铸方坯的表面质量。
With regard to the defec ts such as rhombic contours, slag runners and concaves on surface of continuous casting square billets produced in Steelmaking Plant of Lingyuan Iron and Steel Co., Ltd., the billets were tracked during rolling and then the causes leading to the defects were analyzed based on the inspection results of tested samples. After taking the corresponding measures such as optimizing the inverted taper of the mold copper tube, carrying out the optimal allocation of water and optimizing the properties of mold powder, the above-mentioned defects were effectively controlled and the surface quality of the continuous casting square billets was improved.
