Heat treating furnace at 1,800 °F (980 °C) Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as ...
Ipsen's industrial furnaces - vacuum furnaces, atmosphere furnaces and pusher-type furnaces - are used for the following heat treatment processes: hardening, quenching, tempering, carburization, carbon nitriding, nitro carburization, bright tempering, annealing, vacuum brazing, temperature brazing, plasma nitriding
As of 2024, the largest steel mill in the world that still produces steel using open-hearth furnaces is the Zaporizhstal steel mill in central Ukraine, which has seven 500-ton capacity OHFs and one twin-hearth furnace as well as four blast furnaces. The availability of cheap fuel oil in large quantities, as well as the ongoing invasion, largely ...
For example, a low-temperature vacuum oven can be used for drying biomass much more efficiently than drying alone. [3] Similarly, microwave-vacuum drying has shown potential for drying foods like cranberries. [4] [5] At temperatures below 1200 °C, a vacuum furnace is commonly used for the heat treatment of steel alloys. Many general heat ...
An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty ...
Austempering is heat treatment that is applied to ferrous metals, most notably steel and ductile iron. In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite. It is primarily used to improve mechanical properties or reduce ...
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. [ 1 ] [ 2 ] [ 3 ] Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel , copper , aluminum , and precious metals .
A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold ...
