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.
