Use of High-Magnesia Flux Flumag in Steelmaking

详细

Research results are given for use of FluMag high-magnesia flux mainly containing brucite Mg(OH)₂ during steel production in oxygen converters and electric steel smelting furnaces. Data are provided for FluMag flux physicochemical properties. The effect of using the flux in different periods of converter smelting on molten slag chemical composition and other process parameters, and also the increase in efficiency of applying a slag skull the converter lining are determined. Comparative analysis is carried out for molten slag foaming during steel smelting in electric furnaces and formation of a slag skull on the furnace lining with the use of magnesia fluxes of different compositions.
