Industrial furnace is a thermal equipment that uses the heat of fuel combustion or electric energy conversion to heat materials or workpieces in industrial production. Broadly speaking, the boiler is also an industrial furnace, but it is customarily not included in the scope of industrial furnaces.

Application classification: In the foundry, there are cupolas, induction furnaces, resistance furnaces, electric arc furnaces, vacuum furnaces, flat industrial furnaces for melting metals

Furnaces, crucible furnaces, etc.; sand drying furnaces for baking sand molds, ferroalloy ovens, casting annealing furnaces, etc.; in the forging workshop, there are various heating furnaces for heating steel ingots or billets before forging, and heat treatment to relieve stress after forging Furnace; In the metal heat treatment workshop, there are various annealing, normalizing, quenching and tempering heat treatment furnaces to improve the mechanical properties of the workpiece; in the welding workshop, there are pre-weld pre-heating furnaces and post-weld tempering furnaces for weldments; in powder metallurgy The workshop has a heating furnace for sintering metal, etc.

Applications in other industries, such as metal smelting furnaces, ore sintering furnaces and coke ovens in the metallurgical industry; distillation furnaces and cracking furnaces in the petroleum industry; generators in the gas industry; cement kilns and glass melting and glass annealing furnaces in the silicate industry; food Industrial baking furnaces, etc.
