blast furnaces teriminin İngilizce İngilizce sözlükte anlamı: plural form of blast furnace
blast furnace: a furnace in which iron ore is smelted to iron; the process being intensified by a blast of hot air
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
