2018822Today, the maintenance of heat treatment equipment is a point of major emphasis and this is especially true for vacuum furnaces. This article will explore various aspects of vacuum furnace maintenance providing useful tips and practical techniques to simplify the work and make sure that it is done correctly.
Vacuum oil/ gas /water quenching furnace, heat treatment, hardening, annealing fur nace. Vacuum Technology is the Basis for Process Innovation in Heat Treatment. Heat Treatment is the process in which metallic/steel parts are exposed completely or partially to time-temperature sequences in order to change the mechanical and/or corrosion properties.

Life Improvement of Alloys in Heat Treatment Furnaces and Fixtures. Apr 24, 2013 Heat treatment furnace components and part holding fixtures are comprised of .. Figure 4: Metal dusting schematic of a low-nickel alloy  . .. Vacuum carburizing furnaces are typically used at a higher .
The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 - 99.9% pure. 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.
Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.
Heat Treatment is another operation in MEL which include continuous and batch type gas carburizing, gas nitriding and induction hardening facilities. Heat treatment equipment also includes Tempering furnaces, Rotary Hearth furnaces with Endothermic gas generator to provide & maintain controlled atmosphere inside furnaces.
after heat treatment of a steel object, numerous process parameters need to be controlled. A most critical parameter is the composition, function and control of the furnace atmosphere. In carburising/ carbonitriding processes, the function of the atmosphere is to supply the necessary amount of carbon (and nitrogen) and to provide the right
HKFurnace has been designing, engineering, and manufacturing industrial furnaces and heat treatment equipment for 50 years. Gas Carbonizing Furnace RQ3 series Pit-type gas carburizing furnace of is a high-precision, ultra save energy efficient industrial heat treatment furnace.
an industrial furnace for the heat treatment or thermochemical treatment of metal articles. Heat-treating furnaces are divided according to mode of operation into batch furnaces (tank, compartment, and aerodynamic holding furnaces) and continuous-operation furnaces (induction heating plants and continuous, drawing, and patenting furnaces).
Atmosphere Furnace's are used in heat treating processes to protect the surfaces of work pieces from undesired reactions such as oxidation or decarburization. This furnace also helps to promote surface reactions in order to achieve a desired effect, such as case hardening processes including. carburizing. ferritic nitrocarburizing (FNC)

For this, all the influencing parameters like steel melting, forming of the parts, uniformity of microstructure and hardenability, as well as the natural factors of the heat treatment process - positioning of the parts in the load, uniformity of heating, carburizing and heat extraction during quenching - need to be analyzed and optimized if one
2019324Nitriding and carburizing are the two most common heat treatment practices for surface hardening functional components. The main difference is that in nitriding, nitrogen atoms are made to diffuse into the surface of the parts being processed, whereas in carburizing, Continue reading →
