The purpose of the blast furnace is to separate iron ore extracted from the ground into its component parts: iron and oxygen. A form of carbon, normally coal, combines with the oxygen in the iron ore.
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
How Is Iron Made? To convert iron ore into metallic iron, oxygen and impurities must be removed. This process requires heat and a reducing agent, a substance that combines with the oxygen and releases it from …

First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster. This produces what we have mentioned …
If managers chose to make iron for conversion into steel, their blasts furnaces were attached to large mills where the pig iron could be transferred, while still molten, directly to steel furnaces. Republic Steel in Gadsden At the beginning of the twentieth century, there was large-scale consolidation within the American iron and …
By the late 1600's and early 1700's, iron ore was still being mined in ia and western Massachusetts. Small scale bloomeries, the most primitive form of smelting, reduced the ore into a porous mass of …
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …
