Abstract
PURPOSE:To rapidly and safely attach and detach an inner cap by a remote control by supporting the inner cap by means of a lifter disposed on a lower cover of a vacuum vessel, then engaging and disengaging the engaging member of the inner cap with the engaging part hanging from the upper cover. CONSTITUTION:The inner cap 8 hung via rod parts 6 of hanging rods 5 from the upper cap 3 is lowered together with the upper cover 3 and is mounted on a ladle (not shown) housed in the vacuum vessel 1 and the molten steel or the like in the ladle is vacuum-treated. The inner cap 8 is raised together with the upper cover 3 and is detached from the ladle after vacuum treatment. After this ladle is removed from the lower cover 3 by a crane, a lifter 12 is carried into the lower cover 2. A cylinder 13 of this lifter 12 is extended and the inner cap 8 is supported by a supporting means 17 on the pedestal 14 at the front end thereof. The rod parts 6 are then remotely controlled to disengage the engaging part of the front end thereof from the engaging member at the edge of the inner cap 8. The above-mentioned cylinder 13 is thereafter retracted to detach and lower the inner cap 8 mounted on the pedestal 14 from the upper cover 3 and is replaced or subjected to repair if necessary.
