摘要
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。
A new treatment process for titaniferous blast furnace slag at Pangang using phase separation was put forward. As the first part of the present work,the behavior of separation of molten substance from solid residues was examined.According to thermodynamical analysis and experimental determination,the main products of reaction between titaniferous slag and Na 2CO 3 at high temperature were complex silicon and titanium oxides containing sodium. Furthermore ,under proper condition,it is possible to separate most of titanium and silicon from the rest in the slag.Under experimental condition,the particle size of the slag and temperature of the system influence the reactions markedly.However,the effect of the amount of Na 2CO 3 added is relatively weaker as long as the amount of Na 2CO 3 added is higher than that of stoichiometry.
