Abstract
A metallurgical vessel cover having integral fume collection provisions is disclosed. The cover features a plurality of inlet openings defined about the perimeter of the cover that direct fumes or other gases residing around the exterior of the cover, through the interior of the cover, and to a single collection region. There, the fumes or gases are discharged through a shroud, which preferably is connected to an attachable venting duct. The cover also features an internal configuration for reducing heat transfer through the cover.
