Numerical Assessment of a Filtration Experiment Influenced by Microscale Carbon Monoxide Bubbles Arising in Steel Melt
Abstract
A numerical model based on the assumption that carbon monoxide bubbles form due to reaction between carbon and oxygen on the rough surface of inclusions is introduced to investigate the effects on inclusion removal. The proposed numerical model can be used to determine the growth of such carbon monoxide bubbles on an inclusion, which increases the rising velocity of the inclusion to reach the free surface of the melt faster. The results confirm that formation of carbon monoxide bubbles on the surface of inclusions can considerably increase the number of inclusions removed and thereby improve the cleanliness of steel melt.
