結晶器電磁攪拌在小方坯連鑄上的應用

Application of mold electromagnetic stirring in continuous casting of middle billet

  • 摘要: 簡要介紹了結晶器電磁攪拌在福建三鋼煉鋼廠5#小方坯連鑄機上的應用.理論分析并結合福建三鋼的冶煉條件選擇結晶器電磁攪拌,在長期的生產實踐過程中對結晶器電磁攪拌參數進行優化,實踐表明對減輕品種鋼的碳偏析以及減少中心疏松和提高產品的低倍質量均有明顯的效果.為進一步發揮電磁攪拌在冶金生產中的作用,提出有必要在現有的結晶器電磁攪拌的基礎上增加末端電磁攪拌系統.

     

    Abstract: The application of mold electromagnetic stirring in continuous casting of middle billet in the Steel Work of Sanming Iron & Steel in Fujian Province was introduced. The optimization of the operation pa-rameters of M-EMS has achieved good metallurgical results, such as decreasing the carbon segregation and pre-venting the central porosity. Those measurements are very useful in improving the quality of products. It is pro-posed that final electromagnetic stirring should be used in the end of liquid core.
