Radiant tube furnace or simply tube furnace are
versatile furnace known for their productivity and low maintenance.
These furnace are either gas fired or electricity fired and posses many
features that are essential for the industrial heating. Tube furnace are
designed to handle both light or heavy work loads. The furnace can be
supplied for air atmosphere or endothermic, exothermic, or nitrogen
atmospheres.
Features
Following are the features of tube furnace:
- Lading is easy
- Excess temperature instrument
- Protection from overheating
- Available for various atmospheres
- Well insulated
- In some tube furnace emergency nitrogen gas purge circuit
activates on power failure or loss of atmosphere
- Heat is distributed across the periphery of the furnace
uniformly.
- Fan mounted on roof circulates the atmosphere over the radiant
tubes and through the workload.
- The fan and the fresh incoming atmosphere is blended to assure
mixing and uniform atmosphere.
- Ceramic insulation minimizes the consumption energy and boost the
productivity and efficiency with faster thermal cycling and reduced
heat loss
Applications
The applications of radiant tube furnace are as follows:
- Hardening
- Normalizing
- Carbonitriding
- Brazing
- Annealing
- Carburizing
