METHOD OF STEEL PROCESSING IN LADLE

摘要

FIELD: metallurgy.SUBSTANCE: porous insert through which liquid metal blowdown is performed is installed in the lower part of the ladle at the distance of 200 mm from blowdown assemblies; with that, inert gas supply is performed with constant duration of pulses at constant pressure simultaneously through all the above blowdown assemblies so that inert gas distribution throughout the surface area of the porous insert is provided.EFFECT: invention allows increasing refining degree of molten metal in the ladle from non-metallic inclusions.2 ex, 2 dwg
