low dog briquetted synthetic slag for secondary refining of steel and its production process

摘要

briquetted synthetic slag of high mechanical strength and low dog content for secondary steel refining. The present invention consists in the production of briquetted synthetic slag composed of calditic lime, dolomitic lime, fluorite, recycled aluminum refractory, recycled magnesium refractory and metallic aluminum, with characteristics of high mechanical strength and low dog content, to be used in refining. secondary steel. Its chemical composition may vary depending on a technical evaluation to be carried out according to the steel quality required and the type of deoxidation adopted, the purpose of the treatment, the type of pan refractory lining and the characteristics of the slag itself; viscosity, liquidus temperature, existence of unstable oxides that constitute sources of oxygen during treatment.
