synthetic slag using aluminum sludge to be applied to secondary refining of steels and their production process

摘要

synthetic slag using briquetted aluminum sludge applied to secondary steel refining. The present invention consists in the production of synthetic slag using aluminum sludge composed of alumina, metallic aluminum, fluorine, iron oxide, titanium oxide, calcium oxide, silica, with characteristics of high mechanical strength and low cao content. suitable for application in secondary refining. The chemical composition of the synthetic slag using aluminum sludge may vary depending on the technical evaluation to be performed according to the required steel quality and the type of deoxidation adopted, the treatment objective, the type of refractory lining of the pan and the characteristics of the slag itself. : viscosity, liquid temperature, existence of unstable oxides, which are sources of oxygen during treatment.
