Analysis of desiliconization reaction kinetics in a BOF

A multi-zone kinetic model for analyzing desiliconization in a top blowing steelmaking converter is being proposed. In this model, the vessel is divided into three reactive zones e.g. jet impact, slag-bulk metal and slag-metal-gas emulsion zones. A mathematical treatment of the kinetics of reactions in each zone has been developed. The buoyancy aided chemical reaction rate due to the bloating of metal droplets has been used for analyzing …
