almond furnace: A kind of furnace used in refining, to separate the metal from cinders and other foreign matter
arc furnace: Type of electric furnace in which heat is generated by an arc between carbon electrodes above the surface of the material (commonly a metal) being heated. William Siemens first demonstrated the arc furnace in 1879 at the Paris Exposition by melting iron in crucibles; horizontally placed carbon electrodes produced an electric arc above the container of metal. The first commercial arc furnace in the U.S. (1906) had a capacity of four tons (3.6 metric tons) and was equipped with two electrodes. Modern furnaces range in heat size from a few tons up to 400 tons (360 metric tons), and the arcs strike directly into the metal bath from vertically positioned, graphite electrodes to remelt scrap steel or refine briquettes of direct-reduced iron ore
blast furnace: a furnace in which iron oxide is reduced to iron metal by using a very strong blast of hot air to produce carbon monoxide from coke, and then using this gas as a reducing agent for the iron
blast furnace: A furnace in which solid fuel is burned with an air blast to smelt ore in a continuous operation
blast furnace: 1 A furnace in which solid fuel (limestone, coke, iron ore) is combined with high-pressure, hot air blast (120,000 psi) to smelt ore in a continuous process (They are never stopped They can be slowed down or idled) A Blast Furnace in the iron and steel industry is used to produce liquid iron
blast furnace: a furnace for smelting of iron from iron oxide ores; combustion is intensified by a blast of air
blast furnace: A tall, cylindrical, refractory lined furnace for the production of pig iron or hot metal for direct conversion into steel
blast furnace: A blast furnace is a large structure in which iron ore is heated under pressure so that it melts and the pure iron metal separates out and can be collected. n. A furnace in which combustion is intensified by a blast of air, especially a furnace for smelting iron by blowing air through a hot mixture of ore, coke, and flux. a large industrial structure in which iron is separated from the rock that surrounds it. Vertical shaft furnace that produces liquid metals by the reaction of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, fuel, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel; they are also employed in processing lead, copper, and other metals. The current of pressurized air maintains rapid combustion. Blast furnaces were used in China as early as 200 BC, and appeared in Europe in the 13th century, replacing the bloomery process. Modern blast furnaces are 70-120 ft (20-35 m) high, have 20-45-ft (6-14-m) hearth diameters, use coke fuel, and can produce 1,000-10,000 tons (900-9,000 metric tons) of pig iron daily. See also metallurgy, smelting
blast furnace: where iron ore, coke and limestone are super-heated to create liquid iron
blast furnace: A towering cylinder lined with heat-resistant (refractory) bricks used by integrated steel mills to smelt iron from its ore Its name comes from the "blast" of hot air and gases forced up through the iron ore, coke and limestone that load the furnace Under extreme heat, chemical reactions among the ingredients release the liquid iron from the ore The blast of air burns the coke, and limestone reacts with the impurities in the ore to form a molten slag The hot metal collects in the bottom of the furnace Once fired up, the blast furnace operates continuously until it needs to be relined seven to ten years later
blast furnace: tall cylindrical furnace used for melting metal and iron from ore by way of heat intensified by a blast of air
blast furnace: Blast Furnace is a counter current vertical shaft furnace (refractory lined)which reduces iron oxides present in ores and sinter into liquid iron called hot metal by using coke as fuel and reducing agent Raw materials are charged from the top Fluxes (lime stone and dolomite) are added to remove the impurities which come out as slag Preheated air is blown from the bottom through water cooled copper tuyers to facilitate the reactions in the furnaces and the burden charged from top descends causing the counter current interaction Hot metal and slag are periodically tapped from bottom and gases rising from the top are cleaned and used as fuel in the steel plant
blast furnace: A furnace where mixed charges of oxide or sulfide ores (copper, iron, lead, tin, etc ), fluxes and fuels are blown with a continuous blast of hot air and sometimes oxygen-enriched air to force combustion for the chemical reduction of ores with metals to their metallic states
blast furnace: A towering cylinder lined with heat-resistant (refractory) bricks, used by integrated steel mills to smelt iron from its ore Its name comes from the "blast" of hot air and gases forced up through the iron ore, coke and limestone that load the furnace
electric furnace: any furnace in which the heat is provided by an electric current
electric furnace: furnace in which the heat is generated by electricity
electric furnace: Chamber heated with electricity to very high temperatures, for melting and alloying metals and refractories. Modern electric furnaces generally are either arc furnaces or induction furnaces. Arc furnaces produce roughly two-fifths of the steel made in the U.S. In the induction furnace, a coil carrying alternating electric current surrounds the container or chamber of metal; circulating eddy currents induced in the metal produce extremely high temperatures
furnaces: plural of furnace
gas furnace: a furnace that burns gas
gas furnace: furnace which burns gas fuel
pernot furnace: A reverberatory furnace with a circular revolving hearth, used in making steel
reverberatory furnace: furnace in which the heat is deflected downward from the furnace's roof toward its hearth
reverberatory furnace: A furnace or kiln in which the material under treatment is heated indirectly by means of a flame deflected downward from the roof. Furnace used for smelting, refining, or melting in which the fuel is not in direct contact with the contents but heats it by a flame blown over it from another chamber. Such furnaces are used in copper, tin, and nickel production, in the production of certain concretes and cements, and in aluminum recycling. In steelmaking, this process (now largely obsolete) is called the open-hearth process. The heat passes over the hearth and then radiates back (reverberates) onto the contents. The roof is arched, with the highest point over the firebox. It slopes downward toward a bridge of flues that deflects the flame so that it reverberates
