Discuss The Various Types Of Furnaces Used In Heat Treatment

Laser and plasma heating for surface hardening have limited field.

Discuss the various types of furnaces used in heat treatment.

Gear heat treatment can be done in a wide variety of different types of industrial furnaces each with its own unique characteristics. Of the electric heating methods electric resistance furnaces are the most commonly used furnaces for heat treatment of metals and alloys. These furnaces are very versatile and can be used to manufacture a range of materials including cement clinker and alumina or used for oxidation. Classification of heat treating furnaces.

Case hardening induction hardening and flame hardening are all examples of selective heat treating. Heat treatment furnaces from thermcraft. This equipment is mainly used for the final hardening treatment to finished products which is applicable to various aluminum sections. This article discusses the classification of various furnaces used in heat treating based on the mode of operation batch type furnaces and continuous type furnaces application heating method mode of heat transfer type of materials handling system and mode of waste heat recovery recuperation and regeneration.

Rotary tube furnaces are circular furnaces that rotate during heat treatment and are often used for continuous materials processing as they can apply heat in multiple thermal control zones. Induction heating is the most common perfect and even cheap on mass production of similar parts surface hardening method. Thermcraft have a range of heat treatment furnaces that perform the processes mentioned above and many others. The heating method may be either electric resistance or fuel gas.

This article focuses on the similarities and differences of each of these styles. The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 99 9 pure. Heat treating furnaces can be grouped into two main categories.
