The cutoff of the final slag during steel tapping steel-making units is particularly important for «furnace-ladle» facilities which are widely used now. The said problem's solution depends on technical capabilities of the equipment ensuring slagless steel tapping into the steel-teeming ladle.
RPC «Donix» in collaboration with Donetsk National Technical University (DonNTU) and CJSC «Novokramatorsk Machine Building Works», develops, produces and implements high-performance devices for slag cutoff during steel tapping basic oxygen furnaces, open-hearth and arc furnaces.
Two techniques were developed for basic oxygen furnaces to prevent the penetration of a large quantity of the molten slag into the steel-teeming ladle.
