      slag
    The penetration has a relationship with the separate distribution of slag on the weld surface.
          
    Then, an observation of scanning electron microscopy (SEM) and an electronic data systems (EDS) analysis of slag were performed respectively.
          
    The separate distribution of slag on the weld pool during welding and the great constriction of arc spots were confirmed by TIG welding with helium shielding gas.
          
    The relationship between slag distribution and weld penetration was studied by adding aluminum powder into flux AF305 to change the distribution of slag.
          
    During welding, the separate distribution of slag on the weld pool results in the great constriction of arc spots, an increase in arc spot force, and an increase in Lorentz force within the arc and weld pool.

    For the investigation of a series of problems in connection with the behaviour of fluorine inblast-furnace smelting,an experimental blast-furnace of an effective volume of about 1 m~3 wasbuilt at our Institute by November 1955 together with the necessary auxiliary equipment.Pao-Tou iron ore,which contains fluorite as one of its chief gangues,was smelted in our experimentalblast-furnace with and without previous sintering,and the planned experiments were completed intwo campaigns which lasted for 22 and 36 days respectively.The smelting characteristics ofour experimental blast-furnace are herewith reported together with data on material balance of allthe constituents including fluorine.It was found that nearly all the fluorine went into the slag,while the fluorine content of tht blast-furnace gas was exceedingly low despite the rather highpercentage of fluorite in the charge.

    为了研究包头铁矿的冶炼特性及由于矿石含氟所引起的一系列问题起见,我所于1955年11月筹建了有效容积约为1米~3的实验高炉一座及全部附属设备。1955年11月30日至12月8日及12月20日至12月24日进行了二次试炉。经过设备上的改进后,于1956年1月20日至2月11日及4月23日至5月29日进行了二次冶炼试验,获得设计上所要求的的主要数据后停炉。在实验高炉冶炼试验期间并进行了4次物质平衡的试验。结果发现绝大部分的氟进入炉渣中,进入炉尘中的氟石多,而高炉煤气中的氟极低.

    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。
