一、前言气体搅拌(或喷粉)人们已做了不少模型实验。但是,在这些研究中,大多是在溶液中加KCl溶液表示示踪剂用来模拟渣相或精炼粉剂,以测定均匀混合时间来判断其混合效果。这就忽视了精炼粉剂(或渣相)和金属液之间的不同密度关系,粉剂(渣相)的浮力作用以及粉剂(未熔化前)或渣相在金属液中的分散状况。这是一个重要方面。有鉴于
I. Introduction Gas mixing (or dusting) People have done a lot of model experiments. However, in most of these studies, KCl solution was added to the solution to indicate that the tracer was used to simulate the slag phase or refined powder to determine the mixing time to determine the mixing effect. This ignores the different density relationships between the refined powder (or slag phase) and the molten metal, the buoyancy of the powder (slag phase) and the dispersion of the powder (before melting) or the slag phase in the molten metal. This is an important aspect. In view of
