钢包开浇方法浅析及一种新方法的提出

在连续铸钢生产中，钢包开浇是衔接生产重要的一个环节。在介绍钢包开浇方法时，对很少采用或已淘汰的各种开浇方法行了简要分析，尤其对目前广泛使用的引流砂方法进行了详细分析。最后在引流砂的工作机制基础之上,提出了用铁碳合金颗粒替代引流砂，通过铁碳合金在上水口内形成凝固壳来封堵钢水,然后利用安装在水口周围的感应线圈，对凝固钢壳进行感应加热熔化，从而实现钢包开浇新工艺的设想。

Brief Analysis of Ladle Free-Opening Method and a New Proposed Method

In the course of the continuous steel casting,ladle free-opening is one important link that joins production.While introducing ladle free-opening methods,the pouring methods that were seldom used or eliminated were analyzed;and ladle filler sand method widely used now was analyzed.Finally,based on the working mechanism of ladle filler sand,replacing ladle filler sand using the iron carbon alloy was proposed,and solidification shell was formed to block the molten steel in the ladle upper nozzle,then the induction coil that was installed around the ladle upper nozzle was used for induction until melting,thereby the ladle free-opening was realized.
