<p>An explosion venting device for metallurgical furnace enclosures consists of a plurality of panels adapted for restrictive movement relative to the roof and sidewalls of the enclosure and cover openings therein. The panels absorb the shock blast of an explosion occurring within the housing by lifting outwardly from the housing walls. Being restrictively movably mounted, the blast force may be vented in any desired direction. When the explosive force ceases, the panels will return to their rest position against the housing.</p> |
