TEEMING BARREL Russian patent published in 2011 - IPC B22D11/10 B22D41/50 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy, particularly, to continuous metal casting. Teeming barrel arranged between ladle and mould has vertical channel with two webs 19, 20 arranged on channel bottom end and separator 29 arranged between said webs, at the center. Inner walls 23, 24 of said webs are concaved and arranged to create converging metal flow from outlet channel while outer walls 21, 22 are convex. Separator walls 27, 28 and web walls 23, 24 represent irregularities made up of ledges or recesses. Another version of teeming barrel 26 has vertical channel with lateral outlets 51, 52 made on its lower end. Teeming barrel surfaces 54, 55, 56, 57 located at the level of or below said level of lateral outlet top level have irregularities 54a, 56a.
