DEVICE FOR IN-LINE DEGASSING OF METAL IN CONTINUOUS CASTING Russian patent published in 1997 - IPC

Abstract RU 2098224 C1

FIELD: metallurgy, in particular, metal continuous casting. SUBSTANCE: device includes vacuum chamber with two branch pipes of different length installed in chamber bottom with deepening into hollow of tundish, vacuum line and pipeline connected to one of branch pipes for supply of neutral gas. Upper end of branch pipe with pipeline is located above the level of bottom of vacuum chamber by 0.25-0.8 of its inner diameter. EFFECT: higher efficiency of stream and circulation degassing and reduced consumption of neutral gas. 1 dwg, 1 tbl
