Discuss The Various Types Of Furnaces Used In Heat Treatment

Induction heating is the most common perfect and even cheap on mass production of similar parts surface hardening method.

Discuss the various types of furnaces used in heat treatment. Of the electric heating methods electric resistance furnaces are the most commonly used furnaces for heat treatment of metals and alloys. This equipment is mainly used for the final hardening treatment to finished products which is applicable to various aluminum sections. Heat treatment furnaces from thermcraft. 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.

Heat treating furnaces can be grouped into two main categories. The heating method may be either electric resistance or fuel gas. This article focuses on the similarities and differences of each of these styles. Laser and plasma heating for surface hardening have limited field.

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. Case hardening induction hardening and flame hardening are all examples of selective heat treating. 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. Thermcraft have a range of heat treatment furnaces that perform the processes mentioned above and many others.

These furnaces are very versatile and can be used to manufacture a range of materials including cement clinker and alumina or used for oxidation. The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 99 9 pure. Vertical pit furnace furnaces of this type are used for heat treatment of shaft like parts generator rotors steam turbine rotors which are loaded vertically through the top of the furnace.
