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.

Due to the high temperatures involved most of these furnaces operate under controlled and protective atmospheres, with inert gases such as nitrogen and argon used for initial purging, and gas mixtures or gases like cracked ammonia or hydrogen or endogas used to create a suitable atmosphere as per process parameters.
Ā 
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.

Applications

Heat Treatment Applications

ā‡’ Hardening

Other Applications

Controlled Atmospheric Brazing process is used in critical automotive applications because it ensures superior joint strength. Key aspects of brazing are

ā‡’ Filler Metal ā€“ most commonly an aluminum-silicon alloy that will flow quickly when melted and create strong joints post braze

ā‡’ Furnace ā€“ Inert/Controlled Atmosphere ā€“ retort and continuous (straight and humpback) furnaces

ā‡’ Flux ā€“ generally non-corrosive for aluminum applications; helps to reduce oxides on the metal surface which allows for filler metal to flow

ā‡’ Furnace Atmosphere, either:

  • Nitrogen (N2) ā€“ displaces air/oxygen in the furnace atmosphere
  • Inert gases ā€“ helium and argon; used in brazing metals and ceramics
