摘要 参考文献 相关文章 Metrics 全文: PDF(1118 KB)   摘要: 在本文中,作者综合分析了关于CaO—SiO_2、CaO—SiO_2—Al_2O_3及CaO—MgO—SiO_2—Al_2O_3系统熔渣中α_(SiO_2)及α_(CaO)的测定结果,并加以比较。关于CaO—SiO_2二元系,作者综合了Fulton与Chipman,张禄经与Derge及坂上六郎的实验数据,导出了1600℃时液态渣在整个浓度范围内的α_(SiO_2)及α_(CaO),分别用β鳞石英及固态CaO为标准状态。根据这样算出的α_(SiO_2)及α_(CaO)以及坂上的CaO侧电动势数据,作者导出了一个经验公式,可以用来从已知的电动势数据与α_(SiO_2)计算α_(CaO)。将这个公式应用于CaO—SiO_2—Al_2O_3三元系,算出了三元系熔渣内当Al_2O_3=10、20%时的α_(CaO)。然后将二元系和三元系中的α_(CaO)加以比较,导出了一个新的碱度计算公式。在此式中A1_2O_3显示双性,当碱度较高时它属于酸性,因此可以分子比例与SiO_2相加;反之,当碱度较低时它属于碱性,因此须从SiO_2中扣去。如将MgO以重量百分率与CaO相加,这个碱度公式也可以适用于四元系。由于新的碱度公式所根据的实验数据并不充分,所以它的能否适用须视应用结果如何而定。 Taylor与Stobo由脱硫平衡数据计算了三个熔渣内的α_(CaO),与作者的计算结果不能符合。本文初步分析了造成这个差异的原因。因为这个差异的 Abstract：This is the first of a series of papers with a view to evaluation activities inliquid blast-furnace-type slags.The purpose of this paper is to present new results of calculation for activities of CaO and SiO_2 in liquid CaO-SiO_2,CaO-SiO_2-Al_2O_3 and CaO-MgO-SiO_2-Al_2O_3 systems from existing chemical and electrochemi-caldata with certain assumptions The activities of CaO in the above-mentionedsystems with reference to solid CaO as the standard state are plotted against(%CaO)/(%SiO_2).From a comparison of these ~αCaO-(%CaO)/(%SiO_2)curves,a new expression for basicity has been proposed instead of the simple(%CaO)/(%SiO_2)ratio.The activities of CaO in the various systems concerned becomeapproximately equal at the same basicity when the latter is calculated accordingto the new formula.Alumina shows amphoteric behaviour in the new basicityformula in agreement with the general pattern of slag constitution. 收稿日期: 1956-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 邹元爔 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1956/V1/I2/127 [1] 兰本木贡治等,铁と钢(日本),36(5) ,1(1950) ;37(9) ,13(1951) ;38(9) ,12(1952) .
