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

Abstract RU 2087250 C1

FIELD: metallurgy. SUBSTANCE: the offered device includes vacuum chamber with throttle and discharge outlet in the bottom plate. Discharge outlet enters the working hollow of intermediate ladle. Installed on bottom plate of vacuum chamber, inside the working hollow, along its axis is refractory sleeve having side through holes located at the level of bottom plate of vacuum chamber, and upper end of sleeve is located with clearance below the level of throttle of vacuum chamber. Installed between walls of vacuum chamber and sleeve are two discharge outlets of which one has supplying pipeline. EFFECT: higher efficiency. 1 dwg
