Basing on thermo-simulation in laboratory, experimental study was accomplished to analyze the function mechanism of foaming agent and the foaming influence of its decompound production. The results indicated: function of foaming agents was due to their decompound and inter-reaction at high temperature. And some decompound production of foaming agent can reinforce the foaming ability of refining slag.

采用实验室模拟的方法，针对钢包精炼炉常用发泡剂的作用机理以及发泡剂高温分解产物对熔渣泡沫化性能的影响进行了研究，结果表明：发泡剂的作用主要来源于其组成物质的高温分解以及相互反应；发泡剂分解后部分产物作为高熔点粒子存在于熔渣中，提高了精炼渣的泡沫化性能。
