dcterms:description
Purpose. One of the primary tasks that put the steel producers to the test is to reduce production costs while maintaining high quality. This objective is achieved among others through the optimization of conducted technological processes. Commonly used technology of steel homogenization with inert gases is an important stage in the production of steel in which that objective can be accomplished. Methodology. Tests of hydrodynamic processes occurring during the steel blowing with inert gases process directly in industrial conditions is very difficult or impossible. Therefore, as the primary research method physical modelling was used. In order to carry out the tests described in the article a physical model of the station for the argon purging was used that is working at the VSB-TU, Department of Metallurgy and Foundry in Ostrava. Findings. As a result the study provided values for the investigated process and determined the appropriate location of the gas-permeable fittings in steelmaking ladle's bottom plug. This allows to obtain the required conditions for the steel mixing in the entire volume of ladle's workspace. Research limitations/implications. Tests presented in the article were carried out in the VSB-TU in Ostrava. Due to this fact some research limitations occurs that applies to localization and physical model's specific construction. Therefore, as a result of cooperation between VSB-TU in Ostrava and the Silesian University of Technology will be carried out the construction of the new research station in Katowice. Practical implications. The results of the research constitute the basis to make changes that will allow the optimization to so far used purge of steel technology. Originality/value. The results presented in the article are addressed to the steel producers and it allows to optimize on-going steel homogenization process that takes place in the ladle. Purpose.
