The invention discloses a blowing flow distributing device for double-roller thin-strip
continuous casting. The blowing flow distributing device comprises a groove-shaped flow
distributor body; air inlets are formed in the two ends of the flow
distributor body; channels formed in the air inlets form vertical air inlet channels and a bottom air
inlet channel; an air outlet group is formed in the bottom air
inlet channel; the flow
distributor body is internally provided with a steel liquid containing chamber, and the
molten steel containing chamber is provided with a
molten steel partition plateso as to form an upper
molten steel containing chamber body and a lower molten steel containing chamber body; a molten steel falling hole group is formed in the molten steel partition plate; and a molten steel tapping hole group is formed in the wall surface of the lower molten steel containing chamber body located at the lower part of the molten steel partition plate. According to the blowing flow distributing device, non-uniform flowing of outlet waterflow can be effectively buffered, the tapping amount of tapping holes and the flow rate of molten steel can be effectively decreased, so thatthe high-temperature molten steel can be provide heat for a triangular
molten bath from the lower part, the molten steel flowing out of the molten steel tapping holes can be drive to form an upward floating effect and promote upward floating of molten steel inclusions of the
molten bath with the coordination of
inert gas, the activity degree of the surface of the
molten bath can be increased, cold steel membranes can be reduced, and the thin-strip
continuous casting stability and the thin-strip quality can be improved.
