| Abstract: | Inclusions removal is one of the most important tasks in refining of molten steel. The approaches re-lated to the removal inclusions mainly include:Electromagnetic stirring and argon bottom blowing in ladle, tra-ditional RH and RH with side-bottom blowing, flow control device in tundish, gas curtain and electromagnetic induction heating in tundish, electromagnetic stirring, electromagnetic brake and argon blowing in mold. In this paper, in order to optimize the process of inclusion removal and provide theoretical foundation for refining of molten steel, the related methods and mechanism for removing inclusions in molten steel refining in differ-ent reaction container have been summarized, and the main factors affecting inclusions removal have also been analyzed. |
