Basic knowledge of industrial furnace

The main components of industrial furnace include: industrial furnace masonry, industrial furnace smoke exhaust system, industrial furnace preheater and industrial furnace combustion device, etc. There are many types of industrial furnaces used in the mechanical industry. In the casting workshop, there are cupola, induction furnace, resistance furnace, electric arc furnace, vacuum furnace, open hearth furnace, crucible furnace, etc; There are sand mold drying furnace for baking sand mold, ferroalloy drying furnace and casting annealing furnace, etc; In the forging workshop, there are various heating furnaces for heating ingots or billets before forging and heat treatment furnaces for relieving stress after forging; In the metal heat treatment workshop, there are various heat treatment furnaces for annealing, normalizing, quenching and tempering to improve the mechanical properties of workpieces; In the welding workshop, there are pre welding preheating furnace and post welding tempering furnace for weldments; There are heating furnaces for sintering metal in the powder metallurgy workshop

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, boiler is also an industrial furnace, but it is not customary to include it in the scope of industrial furnace.

Industrial furnaces are also widely used in other industries, such as metal smelting furnaces, ore sintering furnaces and coke ovens in metallurgical industry; Distillation furnaces and cracking furnaces in the petroleum industry; Generator of gas industry; Cement kiln and glass melting and glass annealing furnace in silicate industry; Baking oven in food industry, etc.
