C. ESR of SAE 1020. The remelting experiments were carried out on the U. B. C. 250 kVA ESR furnace of It capacity using water cooled moulds of 200 mm nominal diameter, with an electrode diameter of 76 mm, and used two kinds of slag system: CaF_2+30wt-% Al_2O_3(under Ar) and 50 wt-% CaF+2+30wt-% Al_2O_3+20 wt-% CaO(in air). After the remelting process reached a steady state the system was made to undergo discontinuous oxidation-reduction reactions by point additions of either FeO or Ca powder. The model is used to predict the ingot and slag compostion. The results show that the model is in good agreement with those of practical ESR processes under the experimental conditions. 收稿日期: 1984-05-18      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 魏季和 A.Mitchell 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I5/406 1 Wei Chi-ho (魏季和), Mitchell, A. , The Application of the Mass Transfer Model to the ESR Process on an Industrial Unit, to be published. 2 #12 3#12 4 Mitchell, A. , Int.
