| 摘 要： | 在分析水口堵塞的基础上,结合马钢三炼钢生产实际,采用正交实验法研究了钙处理的喂线速度、喂线量和中间包水口内径对140mm×140mm小方坯连铸低碳低硅高酸溶铝钢水口堵塞的影响.结果表明,提高喂线速度、加大喂线量和增加水口内径可避免水口的堵塞.采用以上工艺,连浇炉数达8～10炉,且铸坯内部和表面质量良好. |

| Abstract: | On the basis of analyzing nozzle clogging, the effects of feeding speed, the amount of Ca-Fe cored wire during Ca-treatment and nozzle diameter on the castablity of billet continuous casting for low-carbon low-silicon Al-killed steel were studied by an orthogonal test in line with the on-site condition of No.3 Steelmaking Shop of Ma-Steel, China. The results showed that increasing the feeding speed, the amount of Ca-Fe cored wire and the diameter of the tundish nozzle can prevent blockage. After adopting these parameters proposed, 8~10 heats could be cast in sequence, and the surface quality and internal quality of the billets are satisfactory. |
