A Quick Guide about the Types of Industrial Furnaces

The normal functionality of industrial furnaces is the heat treatment of metals, which is done to anneal, temper, or carburize and pre-treat the material for the purpose of forging. Although metals are the common materials for such treatments using industrial furnaces, there are other material (s) too that can be heated during the process of preparing them to shape, including glass and some ceramics as well. Irrespective of the material(s), an industrial furnace heats these material(s) to extreme temperatures using different fuels as well as formats. Although an industrial furnace and an oven both are used to heat material(s) for processing, yet there’s a clear-cut distinction between them. Often, these 2 different terms are referred to interchangeably for describing the heating process, but there happen to be some differences between the two; the most distinct one is the range of temperature. Typically, an industrial oven may operate from 250° F up to 900° F while an industrial furnace reaches up to the temperature of even 2000° F or maybe higher than this too.

Types of Industrial Furnaces

When these industrial furnaces first appeared many years back, their very purpose was primarily heating metals to cast, mold, and shape. From its inception, and then for several years afterward, this type of industrial furnace remained the only variety available then. As industrialization proceeded, an industrial furnace became an important part of many industrial operations, serving a variety of applications. Below is a brief description of the most common types of industrial furnaces available today. Industrial furnaces are divided into two major categories depending on the heat source: fuel-fired industrial furnaces and electric industrial furnaces, as described below: 

  • Fuel-Fired Furnaces: Fuel-fired furnaces include gas and oil furnaces, wood furnaces, and coal furnaces. These furnaces burn fuel to create heat. 
  • Electric Furnaces: Electric furnaces include resistance furnaces, induction furnaces, and arc furnaces. These furnaces use electricity to create heat. 

Where Are Industrial Furnaces Used?

Industrial furnaces are used in a variety of industries, such as metal processing, glassmaking, and ceramics. 

  • Metals Processing: Furnaces are used to melt and alloy metals, heat metals before shaping and forming them, and heat metals before treating them (heat treating). 
  • Glassmaking: Furnaces are used to melt and fuse glass. 
  • Ceramics: Furnaces are used to bake clay products, incinerate waste, and create heat for other industrial processes.
