Atmosphere electrical furnace:

Atmospheric electrical furnaces usually pass nitrogen and a small amount of hydrogen or flammable gas into the furnace.

The purpose is to heat objects in almost oxygen-free to avoid oxidation.

There are two types of furnaces: batch furnaces and continuous furnaces:

Batch furnaces commonly include furnace door side opening type, furnace door and workbench lifting type, furnace door upper opening type, car type furnaces, rotary kilns, etc.

Continuous furnaces commonly include conveyor belt atmosphere furnaces (brazing/powder metallurgy), working beam high-temperature atmosphere furnaces, car type tunnel kilns, pusher furnaces, rotary kilns, etc.
