Abstract:
The main method of metal finishing in terms of chemical composition and temperature in modern converter production is out-of-furnace treatment of steel. The duration of stay of metal in the ladle increased several times, which led to an increase in heat losses from the metal, in particular, when blowing metal with inert gas, as well as during transportation of the ladle with metal. While the temperature of steel in the ladle decreased. Therefore, to ensure the required temperature at the next technological operation it is necessary to heat the metal, which will lead to an increase in average p

In this paper we develop a physics-based model for lining erosion in steel ladles.

The flow of slag and steel is due to forced convection induced by inert gas injection, vacuum treatment (extreme bubble expansion), natural convection, and waves caused by the gas stirring. The lining erosion takes place by dissolution of refractory elements into the steel or slag.

Abstract:
In the conditions of JSC Ural Steel, the most costly technological task in the production of high-quality steel is to provide the required sulfur content. The analysis of the sulfur removal in the production of high-quality steel in the technological conditions of JSC Ural Steel was performed. An increase in the sulfur content of the pig iron at 0,007-0,010% of the tapping from the blast furnace until used in an electric arc furnace was founded. The need for preliminary hot metal desulphurization before pouring in the electric arc furnace was justified. The method of calculating the cost of ho

Abstract:
In this paper, evolution of inclusions in an Al deoxidized specialty steel with basic slag refining in the LF-RH process were studied, taking into account of the influence of calcium treatment in the ladle furnace. It was found that inclusions would be modified from alumina into spinel then mainly into solid calcium magnesia aluminates after LF refining, and finally into calcium aluminates at the end of RH refining, irrespective of calcium treatment. When calcium treatment was carried out in the ladle furnace, solid calcium magnesia aluminates largely produced in the LF refining would be mostl

Abstract:
Modern technological schemes of steel production do not allow to achieve low (< 0.01 % S) and ultra-low (<0.005 % S) sulfur content on the production of in the metal directly. That is why out-of-furnace steel treatment is often used to remove sulfur. Desulfurization process of steel depends on the chemical composition of the slag, the time of its formation in the ladle, metal oxidation, conditions of mixing of steel in a ladle, additional technological operations and ladle metal processing. Methods are widely used for desulfurization of steel treatment of steel with solid slag-forming mi

Abstract:
Centrifugal casting offers unique advantages, combining large centrifugal forces with directional solidification to minimize non-metallic inclusions in steel. This study investigates how calcium wire ladle treatment modifies and reduces these inclusions to improve machinability and mechanical performance. Using samples collected at various stages of treatment and final casting, inclusion analysis and mechanical testing were conducted. Results highlight that calcium addition after argon oxygen decarburization (AOD) is optimal for inclusion modification. However, centrifugal forces played a more
