Heat treatment refers to a set of industrial and metalworking processes used to change the physical and chemical properties of metals. This can be done by modifying the microstructure or by changing the chemistry and composition of the metal. Ferrous metals commonly processed include steel, cast iron, alloys, stainless steel, and tool steel, while non-ferrous metals include aluminum, brass, copper, and titanium. Heat treatment furnace manufacturers are commonly found in steel mills, steel foundations, metalworking, electrical, and transportation equipment. This article describes the manufacturing process and other product specifications for heat treatment furnaces. 

a) Annealing – heating a metal to a specific temperature and cooling it in a controlled manner. This creates a sophisticated microstructure and is often used to soften metals for cold working and to improve metal properties. In ferrous alloys, the metal is heated above the critical temperature and then cooled very slowly to form perlite. Pure metals and alloys are deformed by heating to their recrystallization temperature. The non-ferrous alloy is cooled to complete precipitation and refine the microstructure. 

b) Aging –The alloying elements of precipitation hardening alloys are confined in solution resulting in soft metals by allowing the elements to form intermetallic particles.

c) Quenching –Metals cool rapidly, ferrous metals produce harder metals and non-ferrous metals produce softer metals. The tempered martensitic steel is then still too brittle for use and is further tempered by heating the steel below its lower critical temperature. This gives the steel toughness and ductility at the expense of some yield strength.

d) cryogenic and cryogenic treatments –Further transformation of the austenite still present in the metal is done by cooling the metal to very low temperatures. e) Decarburization –

Steel is heated to change its carbon content. When steel becomes austenitic, oxygen and iron react with each other to form slag, which offers no protection against decarburization. Carbon atoms react with the slag to form carbon dioxide and carbon monoxide. This process is commonly used to produce malleable iron in a process known as "whitening".

2. type of oven

Heat treatment furnaces are classified into batch furnaces that are manually loaded and unloaded, and continuous furnaces that automate loading and unloading into the furnace chamber.

a) Wagon Oven –Wagon-type ovens have floors designed as independent moving elements that load and unload for ease of use. With sand or solid seals in place, these are used in non-atmospheric processes.

b) lift furnace –Similar to wagon ovens, the wagon and hearth is raised by a motor-driven mechanism. It can carry heavy and large loads without the need for cranes or other moving mechanisms.

c) Bell-type furnaces –They come with removable covers called bells. These are lowered over the cargo by means of a crane. An inner bell is sealed over the cargo for protection, while an external bell provides heat force.

 

Aluminum heat treatment furnace is a process of heating and rapidly cooling an aluminum alloy to the desired solid solution. During the heat treat process, the aluminum alloy is heated until the alloy constituents dissolve into a solid solution within the aluminum base material. Aluminum Heat Treatment Furnace can be designed to support various shapes, surface finishes and thicknesses for screws, fasteners, nuts, and rivets. The Aluminum Heat Treatment Furnace can also be designed to support various shapes, sizes and depths for various end product applications such as optics assemblies and automobile body parts fabrication.
