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。

This paper selected 7 samples and did a series of experiments about the isochermal absorption and fixation of phosphorus to select one or several suitable crucible residue to study compound fertilizer. The result declare that the absorbed phosphorus and the fixability of the No2,Noll and No21 is smaller than the other samples,for the more the desorpability of the three samples get to 30%- 40%.

为选择合适的含硅熔渣用于复合肥，本文对含硅溶渣样品进行了对磷的吸附与解吸和对磷的固定的测定，实验结果表明，2号、11号、21号三个渣样对磷的吸附量与固定率均比其他四个供试渣样少得多，且此三个渣样解吸率达到了30％～40％。

Lava ball is a globular mass of lava that is scoriaceous inside and compact on the outside; it is formed by the coating of a fragment of scoria by fluid lava.

The columniform samples are made with the pressure of 150?MPa that contain graphite,Al 2O 3,SiO 2 and MgO powder.With samples heated at 1?420?℃,1?500?℃ and 1?600?℃ for 4 hours,MgAlON and 21R-AlN Sialon are synthesized by carbothermal reduction nitridation in the sample,MgAlON and 21R-AlN Sialon occure at 1?420?℃.With tempreture rising to 1?600?℃,MgAlON and 21R-AlN Sialon are increasing.

与高温氧化物相比，碳由于熔点高，热膨胀系数小，导热性好，热稳定性和化学稳定性好，不易被液态金属和熔渣润湿等特点，而成为优质耐火原料，使耐火材料在抗熔渣侵蚀和抗热震等性能方面得到质的飞跃。

The experiment uses 100% city garbage melting slag instead of nature macadam and sand to make concrete specimens, under homoiothermal (20±2)℃ and constant humidity relative humidity (60±5)%, which dry and shrink freely 180d.

As the concentration of FeO increasing, the rate of decarburizing and reaction-dissolving of refractory rises sharply. Meanwhile gas production rate of reduction reaction is increased and motion and foaming of molten slag are also speeded up. The corrosion feature of refractory containing graphite carbon is that the most severity area is slag level (interface of slag-gas phas -refractory) and slag-metal interface comes second, and the lowest corrosion rate is the area of iron-bath.

熔体的组成、温度及熔体与耐火材料间的相对运动对耐火材料的侵蚀产生着很大影响，而熔渣中FeO浓度是最主要的因素，FeO浓度提高，使耐火材料脱碳和反应熔蚀速度呈直线上升，熔体中还原产生气体量增加，熔体涨泡及运动速度提高，这些作用都加快了熔体对耐火材料的侵蚀。

Activity coefficient γCuO0.5 was calculated based on the results of experiments.

在1873K温度条件下，与金属铜溶液平衡的纯氧化铁熔渣中含铜量为2.04%，熔渣中的铜含量随着渣中CaO含量的增加而逐渐减小。
