Extraction of Iron Metallurgy Blast Furnace and Reactions

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

Blast furnace metallurgy Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from

Ironmaking 101 From Ore to Iron with Blast Furnaces

Oct 10, 2017 Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace.. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

THE BLAST FURNACE IRON PRODUCTION

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.

Electric Arc Furnace vs. Blast Furnace Steel Supply, L.P.

Sep 11, 2020 Blast furnace. Uses iron ore as the source of material and coke as the main fuel and sources of energy. Melts iron ore and coke so it can produce pig iron high in carbon content and this is then is fed into a converter to remove impurities. Needs a high investment in facility development and takes up a large space. Easier to produce clean steel.
