Blast Furnace Process
Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2. A blast of hot air is blown into the furnace from the bottom. 3. Coke is the fuel that supplies additional heat, increasing the temperature of the charge. 4.

How Iron Was Made
Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers replaced hand hammers for forging out bars of iron.

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 ...
