Physical and chemical properties of industrial slag containing TiO2 is analyzed,and material properties of the fettling mix for converter such as density,strength,high-temperature stability and slag corrosion resistance are studied afrer adding industrial slag containing TiO2 into fettling mix for converter .

分析了含TiO2工业渣的物理化学特性，研究了在耐火补炉料中加入含TiO2工业渣后对材料的体积密度、强度、高温体积稳定性、抗熔渣侵蚀等性能的影响。

The whole sintering process of SHS converter fettling materials can be divided into three steps. The first step is the decomposition reaction of carbonates and sodium nitrate, which is an endothermic reaction. The second step is the SHS reaction, i. e. thermite reaction, the metal of Al reacts with CO〓, O〓, NO〓, Fe〓O〓 to form Al〓O〓. The speed of thermite reaction is very quick, and accompanied with large amount of heat emission and temperature rise. The third step is the reaction of spinels formation. The Al〓O〓 produced by SHS reacts with MgO to form spinels.

整个SHS补炉料的烧结过程分三步进行：第一步为碳酸盐、硝酸钠的分解反应，属于吸热反应；第二步为SHS反应即铝热反应，金属铝粉与CO〓、O〓、NO〓、Fe〓O〓等反应生成Al〓O〓，反应速度很快，并伴随有巨大的放热和温度升高；第三步为合成尖晶石的反应，SHS反应产物Al〓O〓与MgO反应生成尖晶石。

The furnace protection process is optimized from the following ways: determining the best fettling time and location for various fettling materials,adjusting reasonably the component of end slag,improving slag splashing effect,regulating nitrogen pressure,meeting demands for slag splashing,and so the cost of furnace protection is reduced.

认真分析和实验，从三个方面对护炉工艺进行了优化：确认各种不同补炉料的最佳补炉时间和位置，合理调整终渣成分、改善溅渣效果，调整氮气压力，满足溅渣需求，对护炉工艺进行了优化，从而降低了护炉成本，取得了明显的经济效益。
