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.

The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 99 9 pure. Classification of heat treating furnaces. This equipment is mainly used for the final hardening treatment to finished products which is applicable to various aluminum sections. The heating method may be either electric resistance or fuel gas.

Heat treating furnaces can be grouped into two main categories. Endothermic atmospheres the protective gases used in furnace atmospheres are usually a mixture of hydrogen nitrogen carbon dioxide co2 carbon monoxide co and trace amounts of water. 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. This article focuses on the similarities and differences of each of these styles.

Thermcraft have a range of heat treatment furnaces that perform the processes mentioned above and many others. It can be divided into single door double door skip manual and maneuvering types in terms of its structure and fuel oil fuel gas as well as electric heating types in terms of heating mode it is mainly used to the aging procedures for aluminum sections at. 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. Of the electric heating methods electric resistance furnaces are the most commonly used furnaces for heat treatment of metals and alloys.

Heat treatment furnaces from thermcraft. Case hardening induction hardening and flame hardening are all examples of selective heat treating. These furnaces are very versatile and can be used to manufacture a range of materials including cement clinker and alumina or used for oxidation.
