APPARATUS FOR LINE VACUUM TREATMENT OF METAL UNDER CONTINUOUS CASTING Russian patent published in 1996 - IPC

Abstract RU 2066592 C1

FIELD: metallurgy, metals continuous casting. SUBSTANCE: apparatus for line vacuum treatment of metal under continuous casting has teeming ladle with teeming cylinder in its bottom, located under it vacuum chamber with branch pipe in its bottom, that is dipped into intermediate ladle cavity, and vacuum pipeline connected with vacuum pump. Branch pipe is made with blind bottom with side inclined to bottom of branch pipe output holes, axes inclination angle of which to longitudinal axis of branch pipe is 5 - 60 deg and total area of output holes cross-sections is 0.8 - 1.6 of through canal in branch pipe cross-section. EFFECT: improved process of metals continuous casting. 1 dwg
