Application of Refractory Coatings to Converter Linings by Swirling Technology. 2. Motion of Slag Droplets

摘要

The use of swirling gas jets for more effective application of refractory coatings on the converter lining is considered. Numerical modeling is employed to analyze the aerodynamics of the working space and the motion of converter-slag droplets, in the case where neutral gas is supplied through a special lance with swirling elements. The description of slag-droplet motion to the converter lining is refined; the relation between the parameters of droplet motion and the characteristics of the swirling jet is established. The swirling of the jet mainly determines the trajectory of the slag droplets, regardless of their size. According to theoretical analysis, the use of swirling gas jets wili permit more flexible slag-coating application to the converter lining.
