The improved technology of iron preparation for the oxygen-converter melting

The new energy-saving technology for iron refining in a casting ladle with simultaneous removal of silicon and sulfur in the combined reaction zone is proposed. It ensures the formation of fl oating drops of synthetic slag, which is close to the CaO - SiO2 - Al2O3 - MgO system with a reduced oxidation potential. The desulfurization of iron is proceeded in the bubbling zone through the interaction of sulfur with floating drops of synthetic slag, which have a high absorbtion capacity for sulfides. The formation of the main cover slag is also ensured in order to intensify the desulfurization process and to increase the temperature of iron during its processing.
