| 摘要 |
The invention relates to a fumes-exhausting hood (1, 1 min ) for exhausting noxious fumes arising from melting furnaces or other tiltable preparation vessels (2) during various phases of a melting process, such as charging, melting and discharging. The hood comprises at least one exhaust valve opening (4, 4 min ) and is pivotally mounted via a linkage (8) on a tubular part (14) forming part of the exhaust duct (10) to allow the hood to be raised, lowered and moved aside during the various phases of the melting process. The hood is pivotally mounted about at least three axis, two horizontally disposed axes (S1, S2) through the ends of the linkage (8) and one vertically disposed axis (S3) through the tubular part (14). <IMAGE> |
