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。
