The flexibility of a car bottom furnace makes it a popular choice for processes that require the handling of batches, large and unusual shaped pieces, or multiple configuration loads.
The ability to load with an overhead crane, forklift or other methods provides options that make this type of furnace a common choice.
This furnace can be designed to operate at low temperatures for tempering processes as well as higher temperature annealing and even higher temperature reheating or forging.
Seal the car perimeter to the inside chamber
With these furnaces one of the key features is the ability to seal the car perimeter to the inside chamber. Our designs include fiber lifting seals that are actuated by pneumatic cylinders and mechanical means that provide a good seal to minimize cold air infiltration and heat losses that might otherwise cause wear and thermal damage to the substructure.
Another critical area is the door perimeter seal which can be achieved with a variety of methods by using refractory materials that allow compression and sealing at the same time as providing a solid damage-resistant surface that will last over time.
