Numerical simulation of DeC process on the surface of an iron droplet

Abstract

Decarburization phenomena under the various kinds of initial conditions on a single iron droplet are studied in order to make a prediction of BOF-converter process possible using computational analysis.The main reaction occurs on the free surface by direct oxidation of carbon at the gas-liquid interface with producing the carbon monoxide. It may be controlled by chemical kinetics and mass transport steps. When the high speed jet is impinging, the extremely large amounts of droplets are generated. Because the reaction is mainly occurred on the surface of droplet, it is important to simulate the reaction on a single iron droplet. To make a prediction in a BOF process possible, this work is focused on the simulation of decarburization reaction on a single iron droplet.
