| Abstract Scope |
A key part of the steel refining process is the removal of inclusions present within the body of the melt. Generally, these unwanted materials are removed as the product is stirred or mixed, with small scale particles becoming entrained in large scale flow streams and carried towards the surface of the fluid and the side walls of the vessel. In this study, two such stirring methods were simulated on an industry-scale ladle: bottom-blow gas-stirring and electromagnetic stirring. Transient simulations using the population balance method were then performed using the resulting flow fields of the two stirring method simulations. Removal via bubble transport (in the gas-stirred model), wall adhesion, and surface removal reduce the number of inclusions over time. The effectiveness of the two methods is then compared using this resulting inclusion removal rate. |
