How is Steel Made? Steel Production Process – What …
To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make steel. Modern-day …
Steel Production Process: The Comprehensive Guide
In addition, carbon can increase the steel's cold brittleness and aging sensitivity. 2. Silicon (Si): Silicon is added in the steelmaking process as a reductant and deoxidizer, so calm steel contains 0.15-0.30% silicon. If the silicon content in the steel exceeds 0.50-0.60%, silicon is considered an alloy element.
Making steel | ArcelorMittal

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 …
Direct reduced iron process
The process gases carbon monoxide ( CO C O) and hydrogen ( H2 H 2) are blown into the furnace at temperatures of approx. 1000 °C and flow through the iron ores. The reduction of iron oxides takes place according to the following chemical equations: Fe2O3 Fe2O3 + 3CO + 3H2 → 2Fe → 2Fe + 3CO2 + 3H2O (1) (2) (1) F e 2 O 3 + 3 C O …
