This paper presents an analysis of the same data used in theprevious paper with a view to investigating the equilibria batween silicon and theother components dissolved in liquid iron sach as salfur, carbon and manganese. It is shown that neither the silicon-sulfur nor the silicon-manganese equilibriumis approached in the blast-furnace hearth, although a parellel relationship existsbetween [%S]~(1/2)/(α_(SiO_2))~(1/2) and (%S)/[%S] and also between [%Si]~(1/2)/(α_(SiO_2))~(1/2)and [%Mn]/(%MnO). By using [%Si]~(1/2)/(α_(SiO_2))~(1/2) as an index ot the degree of silicon reduction,it has been found that an increase in slag basicity promotes silicon reduction in theblast-furnace hearth. Consequently, it is possible for the silicon-carbon reaction toapproach equilibrium in the blast-furnace hearth provided that basicity is highenough. The favorable effect of increasing basicity on the degree of silicon reduc-tion is briefly discussed from the view point of the mechanism of reduction. 收稿日期: 1957-01-18      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/Y1957/V2/I1/19 [1] 鄒元爔,金属学报,1(4) ,(1956) .
