    In the previous paper,a new expression for basicity has been proposed for blast-furnace-type slags.It is the purpose of the present paper to correlate thisbasicity ratio with desulfurization power using the data of Hatch and Chipman,Filer and Darken,and Taylor and Stobo on the distribution of sulfur betweenliquid blast-furnace-type slags and carbon-saturated iron.For this purpose,theactivity coefficient of CaS in liquid blast-furnace-type slags with reference to solidCaS as the standard state has been evaluated as a function of the basicity andthe sulfur content of the slags from existing equilibrium data.With the activitiesof CaS and CaO known,it has been possible to calculate the“theoretical”sulfurdistribution curve by plotting(%S)/[~αS],converted to(%S)=1.50,againstauthor's new basicity ratio.It has been found that the calculated sulfur distribu-tion curve fits fairly well the experimental data of various investigators on thesulfur equilibria between blast-furnace-type slags and metal.This fact seems toprovide an evidence for the usefulness of the new expression for basicity proposedby the author.

    本文讨论了各种碱度计算方法,并提出一个新的计算公式,在这个公式中Al_2O_3显示双性。这个公式应用于Hatch与Chipman,Filer与Darken及Taylor与Stobo的生铁脱硫平衡数据,尚可适用。在本文中,根据Hatch与Chipman,Taylor与Stobo及Fincham与Richardson的实验数据,作者导出了γCaS(固态CaS为标准状况)与渣内硫量及碱度的关系,然后结合前文内算出的α_(CaO)数据,导出了硫分配此与碱度的关系。作者计算的硫分配比—碱度曲线与上述诸家的生铁脱硫平衡实验数据颇为符合。

    The effects of fluorine on such properties as viscosity,melting point and desul-furization power of liquid blast-furnace-type slags have been studied.Both syntheticslags and slags obtained from crucible smelting of Pao-Tou ore were used.The syn-thetic slags were of the CaO-MgO-SiO_2-Al_2O_3 type,containing varying amounts ofCaF_2,while the slags from smelting contained in addition a small amount of the oxidesof rare metals.In has been found that fluorine has the effects of lowering the viscosity,lower-ing the melting point and mineralizing the glassy constituents of slags.The resultsof this study are shown as iso-viscosity and iso-melting-point curves on separate com-position diagrams.On the other hand,it seems that fluorine has little effect on theequilibrium sulfur-distribution-ratio between slags and metal,provided that CaF_2 isconsidered as neutral in calculating the basicity ratio.There is some indication,however,that fluorine might cause a slight decrease in the desulfurization power ofbasic slags.Further work is underway at this Institute in order to establish the roleof fluorine and rare metal oxides as far as desulfurization is concerned.The above-mentioned experimental findings are briefly discussed from a pointof view of the ionic constitution of slags.

    在本文中,我们报告了含氟高炉型熔渣的的粘度、熔化性和脱疏力的研究结果。所用熔渣包括坩埚冶炼渣与合成渣,含氟化钙最高达40.7%。试验数据指出氟能显著地降低熔渣的粘度与熔化温度,但对硫在渣、铁间的平衡分配影响较小。因此作为初步估计,在计算硷度时可以将氟化钙视为中性。根据本文试验结果,我们从熔渣的离子结构观点讨论了氟影响熔渣性质的机理。

    A critical survey is made of the thermodynamic data available for deoxidation of steel.TheFe-O and Fe-C-O systems are considered first,followed by equilibria involving such deoxidationelements as Al,Si,Mn,Cr,V,Ti,B etc..The deoxidation power of the various elements iscompared in a conventional log[% O]-log[% E]diagram for 1600℃.The nature of deoxi-dation products and the interaction between oxygen and alloying elements in liquid iron are alsodiscussed in the light of some new published data.

    在本文中,作者首先讨论了Fe-O溶液与H_2O-H_2混合气体间的平衡的较新的实验数据,接着讨论了Fe-C-O系统的平衡。然后重点地分别讨论了铝、硅、锰的脱氧反应平衡与脱氧反应产物的组成.其次较简单地讨论了铬、钒、钛、硼、锆、磷、铌、钽以及某些复合脱氧剂的脱氧能力.最后用脱氧曲线将各元素的脱氧能力作一比较。
