Argonoxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminium. After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization , reduction , and desulfurization .
Rendering of electro-slag remelting apparatus and cross-sections. Electroslag remelting (ESR), also known as electro-flux remelting, is a process of remelting and refining steel and other alloys for mission-critical applications in aircraft, thermal power stations, nuclear power plants, military technology and others.
Argon oxygen decarburization, a process in stainless steel making; Automatic Overdrive transmission, a vehicle transmission; Above Ordnance Datum, a level expressed as a height above mean sea level; Adult Onset Diabetes, a metabolic disorder, characterized by high blood glucose
Stainless steel taps and sink Stainless steel ... AOD process (argon oxygen decarburization), ... is the largest family of stainless steels, making up about two ...
Electrical steel is one material that uses decarburization in its production. To prevent the atmospheric gases from reacting with the metal itself, electrical steel is annealed in an atmosphere of nitrogen, hydrogen, and water vapor, where oxidation of the iron is specifically prevented by the proportions of hydrogen and water vapor so that the only reacting substance is carbon being oxidized ...
Conventional and CPM steel-making smelts ore into steel with an electric arc furnace, refines it by removing some carbon, reducing it by removing the sulphur. [63] Further refining may use argon oxygen decarburization, an implementation of powder metallurgy. The conventional process teems [64] (distributes and pours) the steel into ingot molds ...
Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [1] The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible tightly controlled materials used in biomedical ...
