HarbisonWalker International is a predominant supplier of basic oxygen furnace (BOF) refractories in the United States, where the BOF is the primary device used to produce highquality integrated steel. Domestic BOF steel production capacity has leveled off due to the significant capital investment required to build new integrated steel mills.
calcining system is fired with a single burner that can be designed to accommodate a wide variety of fuels, including coal, pet coke, natural gas, light and heavy oils, blast furnace gas and coke oven gas. Certain waste fuels can also be used. The firing systems can be designed to fire a single fuel, or combinations of two or three
Basic calcining process. Petroleum coke calcining is a three step process, including drying, devolatization and densifiion. The coke calcining process is a timetemperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating rate, air addition rate and final calcination temperature.
Calcination (also referred to as calcining) is a thermal treatment process, in presence of air or oxygen, applied to ores and other solid materials to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The calcination process normally takes place at temperatures below the melting point of the product materials

Electrically calcined anthracite (ECA) is manufactured by heat treating high grade anthracite coal in an electrically "fired" calcining furnace. ECA is heated to temperatures as high as 2000 C, which results in some development of graphitic structure in the finished product.
Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 percent of the total coke production is dedied to blast furnace operations. Foundry coke comprises most of the balance and is used by foundries in furnaces for melting metal and in the preparation of molds.
