FIELD: metallurgy.
SUBSTANCE: invention relates to equipment for out-of-furnace evacuation of liquid steel. Vacuum tank with replaceable lower part of vacuum chamber and balance lever mechanism of vertical movement of vacuum chamber and its parts, containing double-arm lever with counterweight, which is installed with possibility of reversible movement along double-arm lever and is equipped with screw drive of movement.
EFFECT: invention makes it possible to reduce loads on drive of vacuum chamber movement at changes of mass of moved parts depending on version of lower part of vacuum chamber, mass of deposits in vacuum chamber and on branch pipes.
