Abstract

There are two types of desulphurization processes in the steelmaking industry: the KR process and injection process. In the former process refining agents such as CaO particles are initially placed on the bath surface and then dispersed in the bath using an impeller. Meanwhile, the refining agents in the latter process are introduced into the bath with a carrier gas such as Ar and N₂. The efficiency of the two processes depends strongly on the dispersion pattern of the agents in the bath. The agents are usually poorly wetted by molten metal. The main objective of this water model study is to make clear the wettability effect of the agents on their dispersion pattern in the bath. As a first step, many poorly-wetted spheres were simultaneously introduced into a water bath. The dispersion patterns of the spheres were observed with a high-speed camera.
