The Continuous band furnace is built like a wire mesh belt sintering furnace with heating within a muffle & indirect water jacketed cooling, except that in place of the wire mesh belt, an endless strip (band) of stainless steel is used.
A flat layer of powder is fed on the band direct from a hopper. The powder which gets sintered during reduction annealing breaks into lumps at the rear end of the furnace when the band turns 180° around the rear roller (a scraper is also provided).
The length of the cooling section can be significantly reduced by adding a VRRC module.
The band travels within a muffle, either ceramic, cast or wrought alloy.
The band is sooted by a manifold burner to avoid powder adhesion.
The band is driven by pinch rollers and the ends are stapled or welded together.
Gas fired & electrically heated furnaces are offered.
