The 6 Steps To Modern Steel Production Explained

Step 1 – The iron making process. As 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% – % impurities such as carbon which in turn make the metal brittle ...
