FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy. Vessel with open top and internal volume for melted metal contains a cover with bottom looking towards the internal volume of the vessel. The cover is secured to at least one elongated lifting lever and to at least one elongated rotating lever. The lifting lever ensures the cover movement from closed position to the opened position and back. The rotating lever ensures the cover rotation control during movement from opened to closed position and back. At least one of the specified levers ensures force, at least partially compensating the cover weight.
EFFECT: invention prevents cover rotation by hot back side towards the operator near the structure at the access side of the internal volume of the vessel.
