Deformability control of Al2O3-SiO2-MgO-CaO-MnO system inclusions in high carbon hard wire 82B steel

  • 摘要: 分析了高碳硬線鋼82B在冶煉過程中復合夾雜物-鋼液-渣及耐火材料局部動態平衡反應過程及Mn、Si和Al脫氧條件下夾雜物成分變化規律.利用熱力學計算軟件FactSage進一步計算分析了硬線鋼獲得良好變形能力的Al2O3-SiO2-MgO-CaO-MnO五元系夾雜物所需要的條件:鋼液中Al的質量分數控制在(25~100)×10-6時,相應地鋼液中溶解O的質量分數可以控制在(5~20)×10-6.在低熔點區域內,Si的質量分數可以控制在0.1%~1.5%;Mn的質量分數控制在0.2%~1%.

     

    Abstract: Local dynamic equilibrium reaction process for the reactions involving complex inclusions,molten steel,slag and refractory materials in steelmaking of high carbon hard wire 82B steel melt was studied and the compositional variation of the inclusions using Mn,Si and Al deoxidation was discussed.The formation condition of plastic inclusions for the Al2O3-SiO2-MgO-CaO-MnO system was calculated and analyzed by the thermodynamic software FactSage.The results reveal that the mass fractions of Al and O in molten steel are controlled at 25×10-6 to 100×10-6 and 5×10-6 to 20×10-6,respectively.In the low-melting point zone,the mass fraction of Si is controlled at 0.1% to 1.5% and that of Mn at 0.2% to 1%.
