Here is your answer
⏩Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of airintroduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals. Rapid combustion is maintained by the current of air under pressure.
⏩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.
⏩Blast furnaces were first invented in the late 14th century and were improved most significantly by Henry Bessemer during the Industrial Revolution.
⏩A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are also called high ovens. A blast furnace is usually built with a steel case and bricks made of magnesia inside the case.
⏩In the blast furnace, there are several chemical reactions taking place; that eventually result in the desired product (iron) being extracted. The coke (carbon) burns with oxygen to produce carbon dioxide. This reaction is exothermic. The CO2 then reacts with more coke to give carbon monoxide.
