A conveyor belt furnace is a furnace that uses a conveyor or belt to carry process parts or materials through the primary heating chamber for rapid thermal processing. It is designed for fast drying and curing of products and is nowadays widely used in the firing process of thick film and metallization processes of solar cell manufacturing. Other names for conveyor belt furnace include metallization furnace, belt furnace, atmosphere furnace, infrared furnace and fast fire furnace, to just list a few.
Normally a conveyor furnace adopts tunnel structure and is composed of multiple controlled zones which include, but not limited to, preheating zone, binder burn out zone, heating zone, firing zone and cooling zone. A conveyor furnace also features fast thermal responses, uniform and stable temperature distribution; it can heat treated parts to 1050 deg. C. (may vary for different model). Belt speed of a conveyor furnace can be up to 6000mm/min. Products are heated efficiently by infrared radiation (it can also be ceramic heaters or IR lamps) and are dried and fired after passing through the controlled zones, followed by rapid cooling.[1]
