What is the Difference Between an Industrial Oven and An Industrial Furnace?

big oven

Although industrial ovens and furnaces are both fireproof boxes that perform heat treatment processes, they have many differences and functions that are important to distinguish, such as their temperature, heat distribution, and design.

Temperature: One of the biggest differences between an oven and a furnace is their temperature. The maximum operating temperature for an oven is up to 750°C and a furnace heats above 535°C and can rise up to 3,000°C.

Heat Distribution

Industrial Ovens: In ovens, the air is released into a separate heating chamber, which contains a recirculation fan and the heat source, such as a gas burner or electric heating element.

 The amount of recirculated air required is high in order to transfer the heat successfully from the source to the parts under heat treatment.

Industrial Furnaces: The heat is introduced directly to the parts under heat treatment. Depending on the heat source of a furnace, the heat source can be placed in various configurations in order to provide the most uniform heating.

In gas-fired furnaces, burners fire above and below the load, which is elevated on high-temperature structural members called piers or furniture. In gas-fired furnaces, the combustion fans are interlocked with the control system so the gas is shut off if they fail.

In electric-heated furnaces, heating elements are mounted directly into the interior sidewalls and radiate heat onto the load.                        Example of Industrial Furnace

Oven Design

Ovens utilise a sheet-metal interior and exterior that is 18 or 20 gauge. Its insulation consists of a mineral-wool stye that is 75mm at lower temperatures and 100mm thick at temperatures above 260°C. In any industrial oven, the air needs to flow successfully from the air supply duct to the return duct.

Furnace Design

Industrial furnaces are made up of a heavy steel plate exterior of 5-13 mm thickness, and its insulation is 200-300mm thick and either ceramic modules, ceramic blankets, or refractory brick. The thicker the steel exterior shell is, the greater it will help maintain flatness and prevent buckling due to higher temperatures.

Types of Ovens

  • Industrial Electric Oven: Oven that uses electricity and has quick heat-up times, and precision temperature controls. They are good for dealing with combustible products or working with metals like aluminium.
  • Direct Gas Oven: Heats up quicker and maintains temperature longer than an electric or infrared oven. Direct gas ovens have many functions, among them are curing coatings on steel and assisting in the production of automotive parts such as brake pads and linings.
  • Curing ovens: Cause powder or paint to bond with metals, and they harden products from rubber, plastics and various metals. Curing ovens are powered by electricity, UV rays, hot oil, steam or natural gas.
  • Drying Ovens: Remove moisture, heat treat metal for the extrusion process and sterilize medical equipment.
  • Batch Ovens: Heat large quantities of products and come in a variety of sizes and shapes.  

Types of Furnaces

  • Gas and Oil Furnaces: These types of furnaces burn gas or oil to generate heat. When gas or fuel burns, the furnace generates hot gas which is required to heat the room or the metals.
  • Electric Furnaces: Furnaces that convert electricity to heat- they generate heat through heating elements that are made up of wound coils of resistive wire for mid-temperature range, and silicon carbide and molybdenum disilicide for higher temperatures.
  • Kilns: These types of furnaces are used in pottery and ceramic application. They can either be fueled by natural gas or electricity and are typically used for drying, hardening clay and glazes.

Applications

Both industrial ovens and furnaces provide great results in their respective applications and temperature ranges. Due to the greater amount of air being circulated, industrial ovens perform better at lower temperatures. The curing of paint and powder, plastic annealing, aluminium ageing, composite curing, calcination, removing moisture, and adhesive drying are some of the applications of ovens.

Industrial furnaces are used for more robust materials such as metals, and processes such as annealing, tempering, hot pressing, preheating, normalizing of forgings, castings, and carburizing.
