摘　　要：采用热力学软件及静态坩埚抗渣侵蚀试验,研究了RH插入管用镁铬砖抗普钢渣和硅钢渣的侵蚀行为。结果表明:普钢渣对镁铬砖的侵蚀较小但渗透严重,硅钢渣对镁铬砖侵蚀严重,故建议钢厂在使用同一插入管精炼时可先炼普钢后再炼硅钢,这有利于提高RH插入管的寿命。Through process simulation with thermodynamic soft ware and static slag corrosion resistance experiment,the corrosion resistance behavior of RH inserted tube magnesia-chrome brick against common steel slag and silicon steel slag in a steel plant were studied.The results show that the corrosion of common steel slag on magnesia-chrome brick is small,but the penetration is serious,and the silicon steel slag has serious corrosion on magnesia-chrome brick.Therefore,it is suggested that steel plants can refine ordinary steel first and then silicon steel when refining with the same RH inserted tube,which is beneficial to prolong the service life of RH inserted tube.
