The desulphurization of molten slags in the gaseous phase during top-blown with air has been studied from the kinetic standpoint, emphasis being made to study the effects of FeO, the j value (j=N_(Fe_2O_(3))/(N_(Fe_2O_3)+N_(FeO))) and the basicity of the slag upon the rate of removal of sulphur. It has been found that this gaseous desulphurization takes place according to the following reaction: (S~(2-))+3/2O_2=SO_2+(O~(2-)), (1)while the iron ions in the slag serve only as the oxygen-carriers:6(Fe~(3+))+(S~(2-))+2(O~(2-))=6(Fe~(2+))+SO_2,...

The desulphurization of molten slags in the gaseous phase during top-blown with air has been studied from the kinetic standpoint, emphasis being made to study the effects of FeO, the j value (j=N_(Fe_2O_(3))/(N_(Fe_2O_3)+N_(FeO))) and the basicity of the slag upon the rate of removal of sulphur. It has been found that this gaseous desulphurization takes place according to the following reaction: (S~(2-))+3/2O_2=SO_2+(O~(2-)), (1)while the iron ions in the slag serve only as the oxygen-carriers:6(Fe~(3+))+(S~(2-))+2(O~(2-))=6(Fe~(2+))+SO_2, (2)6(Fe~(2+))+3/2O_2=6(Fe~(3+))+3(O~(2-)). (3)With slags containing very little or no FeO or slags with constant j value, as when air is blown upon the slag surface from a rather remote distance, the reaction has been found to be of the first order, the transfer of S~(2-) ions inside the slag being most probably ratecontrolling. An increase in the FeO content and the j value of the slag, as well as the temperature, accelerates the speed of removal of sulphur, while an increase in slag basicity retards it. It has been proposed that, owing to the oxidizing character of the blown-in air, SO_4~(2-) ions might have been formed inside the slag, but at the high temperatures prevailing, they decompose immediately into SO_2 and O_2. Any sulphate that may be present in the solidified slag is most probably being formed on its way of cooling in air. Attention has been called to resort to the correct method of analysis of total sulphur in the slag, the combustion method using CO_2 as the oxidizer being more accurate than the method using pure O_2. It has also been shown experimentally that the direct gaseous desulphurization of the metal is not so feasible as that of the slag, and that there exists some contradiction between the desulphurization of the metal with slag and the gaseous desulphurization of the slag. With a view to bringing about as a whole a more efficient desulphurization, the possibility of adapting the gaseous desulphurization to the actual steelmaking practice with the converter is briefly discussed.

利用空气顶吹研究熔渣的气态脫硫动力学,着重研究了熔渣∑FeO含量、j值[j=N_(Fe_2O_3)/(N_(Fe_2O_3)+N_(FeO))]、以及碱度对气态脫硫速度的影响.对气态脫硫反应的机理及反应速度的限制性环节作了分析和讨论.最后,对金属直接的气态脫硫、炉渣的气态脫硫和炉渣脫硫本身的矛盾、以及气态脫碗在转炉炼钢工艺上的应用问题进行了简要的讨论.

The very vigorous agitation at the interface on molten metal and slag in oxygen side-blown steel-making converters is a special feature which promotes the application of viscous slag operation.

氧气侧吹转炉的特点之一是金属-炉渣界面处搅拌作用特别强烈,它促进了粘渣操作的使用。对比并分析了氧气侧吹转炉不同类型的终点炉渣,发现一些粘稠的炉渣基本上不侵蚀普通焦油白云石炉衬,在某种情况下还可以在炉衬砖上融接上长,控制处理得当,就有保护炉衬的作用。实践证明:采用粘渣操作有利于转炉炉龄的大幅度提高。讨论了氧气侧吹转炉冶炼间隙时期中炉内气氛的性质及其与炉渣的作用情况,从热力学角度上可以证明一些炉气对渣中FeO具有还原能力。在我们的情况下,当炉役平均终渣的∑(FeO)≤12%时,往往形成炉渣在炉衬表面融接上长,其原因主要是该种高熔点的终渣中FeO等低熔点组元被炉内气氛还原,使炉渣熔化温度进一步升高,由液态转变为固态所致。这类上长物的矿物组成主要是3CaO·SiO_2,2CaO·SiO_2;其中2CaO·Fe_2O_3等含铁矿物甚少。

The very severe attack of the dolomite lining of oxygen-blown steel-making converters by high P_2O_5 containing slags has been considered on phase relations. In steel-making practice, no difference was observed between slags of high and of low P_2O_5 content in their attack upon MgO in dolomite linings, but upon CaO in the same linings was more severe and the higher the P_2O_5 content of the slag, the greater the attack. Reasons for these are as follows:

运用相关系研究了氧气转炉中高磷熔渣对白云石炉衬侵蚀甚烈的原因。与低磷熔渣比较,高磷熔渣侵蚀白云石中MgO数量相似,对CaO则较强烈。其原因有三: 一、高磷熔渣于1600℃为均质熔液和对CaO反应力很大的非均质熔液,而低磷熔渣则为对CaO反应力很小的非均质熔液; 二、于1600℃下,高磷熔渣有时为二相熔液,低磷熔渣为单相熔液。二相熔液侵夺CaO甚烈; 三、在高磷渣中,SiO_2含量愈大,则CaO饱和量愈大,熔渣侵蚀CaO愈多。在低磷熔渣内无此现象。对上列缺点,建议在熔渣内提高CaO含量,以资补救。
