Claims8
A preheating apparatus for a metal remelt furnace comprising:
- first and second juxtapositioned chambers,
- a conveyor system for moving metal containing cartridges sequentially through said chambers,
- a duct system for conveying exhaust gases from a source of heat sequentially through said first and second chambers,
- duct means for recirculating a part of the exhaust gases passed through said second chamber back to a portion of said duct system leading into said first chamber,
- fan means within said duct system downstream of said second chambers for drawing the gases through said first and second chambers, and
- damping means within said duct system for controlling the amount of hot gases recirculating through the apparatus and cooling air drawn into the apparatus from the atmosphere,
- said chambers being open ended so that when a pair of cartridges are moved into the chambers opposite ends of the cartridges close opposite ends of the chambers with juxtapositioned ends of the chambers being interconnected with a part of said duct system.
