The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
it is tappered to accomodate the gradual volume expansion of the solid charge as it descends through zones of Stack,from top to bottom in the stack the temperature gradually increases and we need to ascertain smooth burden descent.
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie

Some will give credit to Sir Henry Bessemer invented the modern day blast furnace in 1855. However, if you look historically the Chinese invented the blast furnace. By at least the 4th century the Chinese have developed blast furnaces to obtain cast iron from iron ore. This was 1200 years before the first blast furnace showed up in Europe.
A blast furnace just makes better steel. Invented in the industrial revelution
1ST CENTURY BC During the han dynesty in China
Blast furnace = Hochofen
A blast furnace is used to extract iron from its ore.
Its because air is forced into the furnace to increase temperature. Steve.
Govăjdia Blast Furnace was created in 1810.
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
