摘　　要：通过分析低碳钢矩形大方坯表面横裂纹的影响因素,针对连铸工艺参数、工装精度、设备精度、现场实际操作等提出横裂纹的有效改善措施。低碳钢横裂纹发生率由原18.5%降低至0.05%,矩形大方坯低碳钢角部横裂纹得到了明显改善。The influence factors of surface transverse crack of low carbon steel rectangular bloom were analyzed.In view of the continuous casting process parameters, tooling accuracy, equipment accuracy, field actual operation and so on, the effective improvement measures are put forward. The rate of transverse crack of low carbon steel decreased from 18.5% to 0.05%, and the corner transverse crack of low carbon steel was improved obviously.
