Evaluation of Influence of Fluxing Agents based on Al2O3 on Slag Mode and Process of Steel Desulphurization in EAF

Popis výsledku v původním jazyce

During steel production in EAF, the bath surface is covered with slag that significantly affects the final quality and properties of steel. The use of fluxing agents based on Al2O3 is one of the possibilities how to influence the slag properties in the reduction phase. That task is to reduce the melting temperature and thus the viscosity of basic steel slags in order to increase the steel reactivity. This paper presents the operational experience using fluxing agents for slags based on Al2O3 during steel treatment in EAF under the conditions of the company UNEX a.s. The aim of the operational experiments was to compare the various additions of fluxing agents focused on assessment of the slag mode in the reduction phase of steel production. Samples of steel and slag were taken in plant conditions to assess the slag mode in particular heats focused on assessment of the desulphurization degree, basicity, content of easily reducible oxides, CaO/Al2O3 ratio, sulphur partition coefficient, e
