Cast iron is a high carbon iron alloy produced mostly in blast furnace with a wide range of compositions, which are defined as containing more than 2.1%, and usually less than about 4.5% carbon. It will be made whenever a bloomery furnace smelting iron ore is operated with too low a ratio of ore to carbon in the charge for the combustion air rate.

developments in blast furnace iron making. Introduction Kobe Steel started operation as an integrated steel manufacturing company with the blowing-in of the No. 1 blast furnace (BF) at the Kobe Works in 1959.1) We, as latecomers, faced an issue with burden materials, which forced us into high pellet ratio operation requiring central gas flow.

Jiao et al. studied the corrosion progress of aluminum–carbon composite bricks (ACCBs) in blast furnace iron and slag at different slag basicities and times using the rotating immersion method. The results showed that the corrosion caused by the slag is the lightest and increases with the increase in basicity, while the erosion degree of the ...

Iron oxide is heated in an intense flame fed by carbon fuel. Oxygen in the ore combines with carbon monoxide released from the fuel and is expelled as CO 2. What is left is iron. The blast furnace's height lets the rising gases preheat the ore and gives the iron more distance to descend as it softens – so it absorbs more carbon from the fuel.

Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...

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. The word 'blast' gives the idea of combustion air which is forcefully supplied or produced to the atmospheric pressure above.
