A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [1]
blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top.
Blast furnaces are similar to furnaces, but can smelt only raw ore, ore blocks and tools / armor made of iron, gold or chainmail. Blast furnaces serve as the counterpart to smokers, which are used mainly to cook food faster. Smelting equipment yields one iron or gold nugget from their respective materials.
A blast furnace is a special type of cylindrical furnace, which is basically used for the purpose of smelting. So, the industrial metals can be extracted from their ores like iron, pig iron, or copper.
Jun 23, 2013 · Blast furnace (BF) ironmaking is the most viable means of producing hot metal (HM) mainly because of its well established and proven performance, flexible raw material usage, and high thermal energy conservation capability.
A blast furnace is a counter-current gas-solid reactor where the ascending gas reacts with the descending solid bed, producing hot metal as the main product.
Blast furnace slag (abbreviated GGBFS, for ‘ground granulated blast furnace slag’) is broadly described as a mixture of poorly crystalline phases with compositions resembling gehlenite (2CaO·Al 2 O 3 ·SiO 2) and akermanite (2CaO·MgO·2SiO 2), as well as depolymerized calcium silicate glasses. The degree of depolymerization largely ...
