This investigation was carried out in order to see the oxidizingaction of different atmospheres such as oxygen, nitrogen, water gas and air. Experimentswere also conducted on large rimmed steel ingots to control the rimming action by control ofadmission of air to the mold during solidification. Analyses of steel bath, segregation and dis-tribution of impurities in the ingot were made. It is concluded that secondary oxidation duringteeming and rimming is the main source of oxygen. Segregation of steel ingot may be reducedby the control of rimming action with the aid of regulation of air admission to the rimmingbath in the mold. 收稿日期: 1959-04-18      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 王清辉 张顺南 董林嵩 师昌绪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1959/V4/I4/287 [1] 王清辉等,压力对沸腾钢锭结构和偏析的影响.
