A belt furnace is a continuous furnace that uses a conveyor or belt to carry process parts or material through the primary heating chamber for rapid thermal processing. It is designed for fast drying and curing of products and is widely used in the firing process of thick film. Other names for these furnaces include continuous furnaces, continuous process furnaces and conveyor belt furnaces.
Normally a belt furnace features a tunnel structure and is composed of multiple controlled zones which include zones for preheating, binder burn out, heating, firing, and cooling. These industrial furnaces also features fast thermal responses, uniform and stable temperature distribution.
A typical belt furnace consists of:
- Pre-heating section
- Binder burn out section
- Heating section
- Firing section
- Cooling section
