提出采用相分离法处理攀钢高炉渣新工艺。作为本研究内容的第一部分 ,考察了熔渣分离过程的基本规律。经热力学分析和实验测定 ,在高温下攀钢高炉渣与Na2 CO3反应的主要产物为硅和钛的含钠复合氧化物。只要条件适当 ,可以实现大部分硅和钛与炉渣中其它组分相互分离。在本实验条件下 ,炉渣粒度和体系温度对反应影响比较显著 ,在满足化学计量配比前提下 ,配碱比对反应的影响不很明显。
Proposed a new phase separation process of Panzhihua blast furnace slag new technology. As the first part of this study, the basic rules of the slag separation process were investigated. The thermodynamic analysis and experimental results show that the main products of the reaction between blast furnace slag and Na2CO3 at high temperature are sodium-containing composite oxides of silicon and titanium. As long as the conditions are right, most of the silicon and titanium can be separated from each other in the slag. Under the experimental conditions, the influence of slag particle size and system temperature on the reaction is significant. Under the premise of meeting the stoichiometric ratio, the influence of the ratio of alkali to the reaction is not obvious.
