Loading material into the furnace.
A porous, gray, non-melting substance produced by dry distillation of bituminous coal, oil, or coal tar to release a large amount of heat during combustion. Used as fuel in smelting processes.
An electrical contact assembly’s element of self-backing and ready-made (carbon, graphite) electrodes. Designed to conduct current from the short net’s water-cooled conductive copper tubes to the electrode’s steel casing or electrodes themselves.
A machine for reducing metallic fragments, ore, agglomerates, or other materials to the required fractional composition.
The process of removing dissolved oxygen out of molten metals (mostly steel and other iron-based alloys), that is a detrimental impurity degrading the metal’s mechanical properties. Elements (or their alloys, such as ferroalloys), that have a higher oxygen affinity than the base metal, are used in deoxidation. For example, ferrochrome …
A software-hardware complex designed to automate the electrical and technological parameters of furnace operations and operating as a part of a measuring system.
A graphite or carbon cylinder or rod used as electric current conductors in electric arc smelting furnaces, etc.
A general term used to indicate that equipment: (a) has stopped completely, (b) is still operating but unable to perform all of its functions, or (c) has come to the point of no safe operation.
An iron alloy that contains a sufficient amount of one or more chemical elements as alloying or reducing additives.
Materials containing SiO2, Al2O3, CaO, MgO, and other components forming the most stable chemical bonds with oxides (the reduction reaction products). These materials introduced into the charge to lower (raise) the slag melting temperature, reduce slag viscosity, and diminish the impurities concentration in the ferroalloy. That in turn results in …
