Mathematical modelling of change technology the pure oxygen blowing on surface of liquid bath by additional oxygen fuel burner in metallurgical aggregates

Abstract

This paper describes possibility of numerical solution of multiphase flow in metallurgical aggregate for steelmaking by software Fluent 6.3.26. In the first part method of mathematical modeling multiphase flow is described. Model of furnace contains liquid steel and gaseous phase 1 (clean oxygen) which is blown on surface of liquid bath through the gaseous phase 2 (air) by means of refine nozzles and additional fuel oxygen burner. One or two oxygen nozzles are used in operating condition. In the second part of paper is defined change of technology the pure oxygen glowing on surface by one or two oxygen fuel burners. Contribution includes information about velocity field distribution inside of furnace by using two variants of pure oxygen blowing on surface.
