Abstract: Disclosed is a tundish assembly having fume collection provisions. The tundish assembly includes a tundish, a tundish cover, and a tundish hood. The hood has provisions for connecting the assembly to a vacuum source or other air moving means to thereby draw fumes or gases from the interior of the tundish out through the hood.

Abstract: A torch cutting and fume collecting enclosure is disclosed that is particularly adapted for the collection of lead-containing fumes and gases emitted during cutting of steel strands. The enclosure comprises a plurality of walls and two flexible barriers disposed on opposite ends of the enclosure, one at a receiving end, and the other at an output end of the enclosure. The enclosure further comprises a unique air handling system comprising one or more collector hoods, ducts and plenums for collecting and moving air and other gas flows from the enclosure for subsequent treatment and/or discharge. The air handling system utilizes a unique tapered configuration for one or more plenums that reduces the tendency for particulates to separate from an air or gas flow.

Abstract: An apparatus and technique for collecting fumes from a metallurgical vessel such as a ladle are disclosed. The apparatus and technique are particularly well suited for collecting fumes during a cleanout operation of one or more discharge ports along the bottom of the vessel when the vessel is inverted on its side.

Abstract: An improved dumping bay particularly adapted for preventing the escape of hazardous fumes into other areas of a facility is disclosed. The dumping bay is fully enclosed and utilizes a unique air flow routing technique for collecting fumes, such as from a ladle during a slag dumping operation.

Abstract: A comprehensive fume collection system, particularly adapted for the collection of lead-containing fumes or gases typically emitted during the manufacture of leaded steel, is disclosed. The preferred fume collection system comprises four sections, each serving a particular portion of the steelmaking process--(i) a casting floor fume collection system, (ii) a ladle slag dumping fume collection system, (iii) a tundish cooling fume collection system, and (iv) a torch cutting fume collection system.

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.
