Predicted inclusionremoval rates are validated with measurements based on samplescollected from operating degassers. The results quantify theimportant role of argon gas bubbles on the inclusion removal mechanism.

The goal of the project was to increase steelmaking capacitywith the least capital cost. This paper describes the major equipmentmodifications that were carried out during the caster conversion.
查看更多>>摘要：A mathematical model of the CAS-OB process hasbeen developed. The model is based on fundamental transportequations and includes the solution of three phases (liquid steel,liquid slag and gas). Model predictions have been compared tophotographs of the open eye size of the gas plume and agreement hasbeen found to be good.
