capable of producing 1000 to 1200 lbs/hour of light gauge stampings running at a belt
speed of 14 “/min. and a loading density of 12 lbs/SF. The 48 inch wide belt is of fine closed
weave design in order to prevent part mixing. The full range of furnace belt adjustment is
10-20”/min. The furnace opening at the preheat has been closed down to about 2” because
the original part loading was 1” at Tinnerman. The overall height can be easily increased to
6” for commercial use.

and all tubes have recuperators. The temperature operating range is 1475-1725˚F.
Maximum temperature is 1900˚F. There are two zones with Fanuc PLC2 Honeywell

The furnace is currently set up for endothermic atmosphere. We can provide a conversion to
nitrogen methanol if required. Methane additions are provided and an ammonia flowscope
can be provided and desirable if one wants to be able to carbo-nitride or carbo-austemper
parts.
