摘要/Abstract

摘要： 利用扫描电镜对镁钙砖反应层进行能谱分析,研究了120t AOD氧化期渣碱度(CaO/SiO₂-1.0～3.1)及渣中TFe(5.0%～20.0%)、MgO(1.7%～12.0%)、Cr2O3(8.0%～30.0%)对镁钙质炉衬侵蚀的影响。结果表明,氧化期渣碱度和渣中TFe含量是镁钙质炉衬侵蚀的重要影响因素,增加炉渣碱度(CaO/SiO₂≥3),降低渣中TFe含量(≤15%)可明显减少对炉衬的侵蚀。渣中含4%～12%MgO、15%～30%Cr₂O₃时对炉衬侵蚀的影响较小。

Abstract: The effect of slag basicity(CaO/SiO₂- 1.0~3. 1),TFe(5.0%～20.0%),MgO(1.7%～12.0%), Cr2O3(8.0%~30.0%)in slag on magnesia-calcia lining of an 120 t VOD unit has been studied by using scanning elec- tron microscope analyzing the energy dispersive spectrum of reaction layer of magnesia-calcia brick.Results showed that the slag basicity and TFe content in slag were the important factors for magnesia-calcia lining erosion; with increasing slag ba- sicity(CaO/SiO₂≥3)and decreasing TFe content in slag(≤15%),the lining erosion decreased obviously; and as MgO content was4%～12%,Cr₂O₃ was 15%～30%,the effect on lining erosion was minor.
