Properties of Slags in the System CaO-MgO-Al2O3-SiO2, Important in Deoxidization and Desulphurization of Low Carbon Aluminium Killed Steels
Keywords:
CaO-MgO-Al2O3-SiO2 system, surface tension, interfacial tension, viscosity, density, sulphur solubility
Abstract
Properties of refing slags belonging to the system CaO-MgO-Al2O3-SiO2 are important in simultaneous or succesive refinig treatment processes in the ladle and other refing metalurgical reactors. The efficiency of treatments depends upon the values of physicochemical properties of treatment slags which become important technological parameters. Surface tension of slags and interfacial tension in the system slag steel also, viscosity and density are important in managing refining processes which must be correctly evaluated as values and influence exerted by modification of slag composition, mainly by sulphur content.
