MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.

铁浴中硅和钛的扩散是影响铁浴及熔渣与耐火材料作用的重要因素，耐火材料中添加的TiO〓和SiC受熔渣氧化和侵蚀，将被部分还原形成Si，Ti向铁浴中扩散，Si、Ti在铁浴中的扩散研究结果是： D〓=1.84×10〓exp（－5988.7/T） cm〓/S E〓=49766 J/mol D〓=7.76×10〓exp（－53225.5/T） cm〓/S E〓=442304 J/mol 铁浴式熔融还原熔体对粘土砖，高铝砖，镁砖的侵蚀速度很高，镁碳砖抗侵蚀能力比前几种耐火材料强，但不如铝碳砖；对不含碳耐火材料在熔体中的侵蚀是熔渣中FeO及其它氧化物与耐火材料组分的化学反应形成低熔点物熔蚀进入渣相，产生损毁。

The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.

The following results are obtained by physical and mathematical simulation.The pouring height of the tundish has a certain influence on the quantity of the slag involved in the mould with the same tundish structure and production conditions. The slag quantity reduces as the liquid level rises; when the fluid level is under of a critical height the confluence vortex will appear near the nozzle, which easily entraps the slag.

通过物理模拟和数学模拟，得出以下结论：(1)在相同中间包结构和生产条件下，中间包浇注液面高低对下渣量有一定影响，随着液面升高中间包下渣量降低；当中间包钢水液面低于一临界高度时，则会在水口附近形成汇流旋涡，容易造成卷渣。

Reducing agent carbon reduces oxide of cobalt, nickel and iron,and sulfuring agent Fe_2S forms trickles of matte at high temperature, inthe process of assembling and settling of trickles of matte slag is washed,reduced metals of iron, cobalt and nickel and sulphide in slag are enrichedin the matte to form cobalt matte and be separated from slag due to theirintimity to the matte, washing of the matte and their settling.

在高温下，还原剂碳将钴、镍、铁氧化物还原成金属，同时硫化剂硫铁矿形成锍滴，在锍滴聚集沉降过程中对炉渣进行&洗涤&，由于金属及金属硫化矿的亲锍性，锍体的&洗涤&作用及金属及金属硫化矿的沉降作用使被还原的钴、镍、铁金属及转炉渣中的金属硫化矿富集到锍体中，与转炉渣分离，形成钴冰铜。

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

4依据对含氟熔渣中高温条件下（1450℃、1505℃）的各种元素含量的变化情况，发现氟在熔渣中是以碱金属氟化物挥发，并且，KF比NaF具有更好的挥发性，在氟的挥发中占主导地位，理论研究也证明，在1505℃试验组成的熔渣中，KF的饱和蒸气压是NaF的31.4倍；在含氟量远大于钾含量的情况下，KF挥发为一级反应，受钾浓度控制，其表观活化能为275.30KJ／mol。

The results show that magnesium and aluminum theoretically can be thoroughly dissolved from the blast furnace slag by diluted sulfuric acid pretreatment on the blast furnace slag even if the ended concentration of sulfuric acid is 0.001mol/L, while the titanium basically could not be dissolved. Therefore it is theoretically indicated that the separation of the magnesium and aluminum from the slag with the least titanium loss by diluted sulfuric acid pretreatment is possible.

结果表明，采用稀硫酸对高炉渣进行预处理，当终酸浓度即使为0.001mol·l~(-1)时，镁、铝理论上也能全部被酸浸出，而钛在0.001 mol·l~(-1)的酸浓度条件下基本不被浸出，从而从理论上可以说明对高炉渣采用稀酸预处理可以很好的将炉渣中的镁、铝等杂质分离出来，而钛极少被浸出。

The main ways to solve these problems are as follow: 1 to mix steel slag with cement clinker, grained iron slag and fly ash to improve the activity of mixture and the intensity of steel slag cement ; 2 to add suitable excited agent, such as calcium sulphate and sodium silicate.

根据对大掺量钢渣水泥的组分活性差和强度低的主要影响因素及其解决方法进行试验的结果认为：可以通过掺加水泥熟料、粒化高炉渣和粉煤灰的方法来改善钢渣的物质组成，进而提高其强度，但必须加入适当的激发剂。
