ABSTRACT:
A fumes control system for use with a furnace having a top-chargeable furnace vessel mounted on a first support with means for charging the furnace adjacent to the vessel and means for collecting the melt from the furnace adapted to overlie a second support defining a tapping site adjacent to the furnace vessel. The fumes control system comprises a housing covering the top and sides of the furnace in sealing engagement with the first and second supports and is adapted to entirely enclose the furnace and collecting means. The fumes control system further comprises exhaust means with dampers associated therewith, which dampers are interconnected via control means to selectively exhaust fumes generated during charging, melting/refining and tapping operations at the respective sites.
