摘要

钢渣中Al2O3/TiO2/Na2O组分对MgO耐火材料腐蚀速率和腐蚀机理的影响，对促进无氟熔剂在炼钢过程中的发展具有重要意义。本研究采用静态法分析了Al2O3/TiO2/Na2O组分对MgO耐火材料腐蚀速率的影响，通过测量相同反应时间后最终炉渣中MgO的含量来表征。结果表明，MgO耐火材料的腐蚀速率是由FetO在炉渣中向坩埚的扩散以及MgO与FetO的化学反应控制的。当每种氧化物的含量小于15%时，矿渣对MgO耐火材料的腐蚀能力如下：Na2O

Effect of Al2O3/TiO2/Na2O component in steelmaking slag on the corrosion of MgO refractories

ABSTRACT The influence of Al2O3/TiO2/Na2O component in steelmaking slag on the corrosion rate and mechanism of MgO refractories is significant for promoting the development of non-fluorine fluxes in steelmaking processes. In this study, static method was used to analyze the effects of Al2O3/TiO2/Na2O components on the corrosion rate of MgO refractory, which was characterized by measuring the MgO content in the final slag after the same reaction time. The results showed the corrosion rate of the MgO refractory was controlled by the diffusion of FetO in the slag to the crucible and the chemical reaction of MgO with FetO. When the amount of each oxide was less than 15%, the ability of the slags to corrode the MgO refractory material were as follows: Na2O
