Ironmaking Process - an overview ScienceDirect Topics

2012-4-4  The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical reactions will take place.

Steelmaking and Refining Introduction to Chemistry

Steelmaking OverviewPrimary SteelmakingSecondary SteelmakingHisarna SteelmakingRefiningWrought IronSteelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required. Modern steelmaking processes are broken into two categories: primary and secondary steelmaking. Primary steelmaking uses mostly new iron as the feedstock, usually from a blast furnace. Secondary steelmakin

The 6 Steps To Modern Steel Production Explained

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.
