Abstract：The migration of Ti between Ti-containing slag and molten iron was found to be controlled by the diffusion of Ti ions in slag under the experimental conditions. The apparent order of reaction was detected to be of quasi-zero, and the apparent activation energy to be 258kJ/mol. The effects of some factors such as content of Ti in slag, basicity and temperature on the rate of migration have been also discussed. It seems that the basicity of slag serves a dual influence: to increase the basicity in slag with higher TiO_2 content may restrain from the reduction of Ti, while with lower TiO_2 content may accelerate the Ti reduction. Two distinguished regions of the restraint and acceleration of the reduction of Ti by Si may be drawn by wt-% ratio [Si]/[Ti] on the basis of thermodynamical analysis. 收稿日期: 1987-02-18      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 杜鹤桂 沈峰满 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/177 1 森一美,鉄と鋼,1960;46(5) :548 2 冶金部钒钛矿冶炼试验组,资料汇编,1978． 176-216 3 朱伟勇等编著.最优设计理论与应用,辽宁人民出版社,1981,250 4 詹庆霖,冀春霖,东北工学院学报,1981;(3) :59 5 日本鉄鋼協会.溶铁.溶滓物性值便覽,1971． 77-115 6 斯波忠夫,慶伊富長,尾崎萃共著,触媒化学概論(新版),共立全書,1968,32 7 芦塚正博,德田昌则,大谷正康,鉄と鋼,1968;54:1437 8 黄希祜,钢铁冶金原理,冶金工业出版社,1981,210 9 伊藤公久,佐野信雄.鉄錮,1981;67:2131 10 杨祖磐,赵乃仁.东北工学院学报,1981;(3) :53 No related articles found!
