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

Abstract RU 2066591 C1

FIELD: metallurgy, metals continuous casting. SUBSTANCE: apparatus for line vacuum treatment of metal under continuous casting has teeming ladle, vacuum chamber with branch pipe mounted in its bottom, that is dipped into intermediate ladle working cavity, vacuum pipeline and teeming cylinders mounted in bottom of intermediate ladle. Intermediate ladle inner cavity is divided for four zones by partitions and protrusion, that is mounted along branch pipe axis and cross-section of which has trapezoidal form with planes inclination angle at base - in limits of 15 - 45 deg. Height of protrusion is 0.1 - 0.4 of height of two extreme partitions and space between axes of the partitions and axis of protrusion is 0.2 - 0.3 of space between axes of teeming cylinders. EFFECT: improved process of metals continuous casting. 1 dwg, 1 dwg
