摘要: 在分析水口堵塞的基礎上,結合馬鋼三煉鋼生產實際,采用正交實驗法研究了鈣處理的喂線速度、喂線量和中間包水口內徑對140mm×140mm小方坯連鑄低碳低硅高酸溶鋁鋼水口堵塞的影響.結果表明,提高喂線速度、加大喂線量和增加水口內徑可避免水口的堵塞.采用以上工藝,連澆爐數達8~10爐,且鑄坯內部和表面質量良好.

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.
