Making iron & steel
Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...

How steel is made
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I.
HOW A BLAST FURNACE WORKS
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into

Hint: We have to draw the diagram of the blast furnace used in the extraction of iron. It is used for the common ores like iron oxides to extract the iron with the help of reduction with carbon. The apparatus consists of many parts like hot air blast, tap hole etc. Design the blast furnace. First, let us know about the use of blast furnaces.
Extracting Iron from Iron Ore in a Blast Furnace
The iron is extracted from its oxide ore called Hematite. Many things are produced in the extracting or iron from iron ore in a blast furnace. The iron ore is reacted with carbon and oxygen in the furnace to produce carbon dioxide and iron metal. Carbon monoxide is also produced so that it can react with the iron ore to produce the iron.
