Continuous Mesh Belt Furnace (High-Temperature) by Therelek
A multi-zone control environment is present in a continuous high-temperature furnace, often with a single pre-heating zone, followed by multiple heating zones and then cooling zones before exit.

The heating chambers are either dense ceramic-based construction or muffle based. Specially designed corrugated muffles (metallic) are used to withstand thermal expansion for certain processes.
Metallic muffles may be of stainless steel or high nickel and chromium-based alloys. Therelek offers plate belt furnace and conveyor chain furnace for conveying heavier jobs or components.

Brazing
Controlled Atmospheric Brazing process is used in critical automotive applications because it ensures superior joint strength. Key aspects of brazing are
- Filler Metal – most commonly an aluminum-silicon alloy that will flow quickly when melted and create strong joints post braze
- Furnace – Inert/Controlled Atmosphere – retort and continuous (straight and humpback) furnaces
- Flux – generally non-corrosive for aluminum applications; helps to reduce oxides on the metal surface which allows for filler metal to flow
- Furnace Atmosphere, either:
- Nitrogen (N2) – displaces air/oxygen in the furnace atmosphere
- Inert gases – helium and argon; used in brazing metals and ceramics

FAQs
What is a continuous furnace?
Continuous furnaces are classified according to the number of heating zones, the method of moving the heated parts continuously through pre heating, soaking & cooling zones.
The temperature in continuous furnaces is constant over time and variable over the length of the furnace. In the heating and soaking zones the temperature is almost constant; in the holding zone it decreases toward the front of the furnace.
