The 6 Steps To Modern Steel Production Explained - Metro

Step 1 – The Iron Making ProcessStep 2 – Primary Steel MakingStep 3 – Secondary Steel MakingStep 4 – CastingStep 5 – First FormingStep 6 – The Manufacturing, Fabrication and Finishing ProcessAs iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated. Step 2 does exactly this.
