本文得到Ti在含TiO_2熔渣与熔铁之间的迁移规律如下:该过程受渣中Ti离子扩散的控制,其表观反应级数为准零级,表观活化能为258kJ/mol.讨论了渣中TiO_2含量、碱度和温度对Ti迁移量和迁移速度的影响.发现了炉渣碱度对Ti迁移的两重性影响:当渣中TiO_2含量较高时,提高碱度将抑制Ti的还原;而在TiO_2含量较低时,提高碱度则促进Ti的还原.并根据热力学分析,认为按[Si]/[Ti](wt-％)的大小可划分出Si促进或抑制Ti还原的区域.
In this paper, the migration rule of Ti between molten slag and molten iron is obtained as follows: The process is controlled by the diffusion of Ti ions in the slag, the apparent reaction order is quasi-zero and the apparent activation energy is 258 kJ / mol. The effect of slag basicity on the migration of Ti was studied. The effect of slag basicity on the duality of Ti migration was found: when the content of TiO_2 in slag was high, the increase of basicity would restrain the reduction of Ti; However, when the content of TiO_2 is low, the increase of alkalinity promotes the reduction of Ti, and according to the thermodynamic analysis, it is considered that the area of Si reduction or reduction can be divided by the size of [Si] / [Ti] (wt-%).
