: Limestone acts as a flux, combining with impurities like silica to form slag , which floats on the molten iron and is removed. 2. Primary Steelmaking
: This process primarily uses recycled steel scrap . High-power electric arcs melt the scrap, making it a highly efficient recycling method. 3. Secondary Steelmaking and Metallurgy Fundamentals of Steel Making
This stage transforms molten iron or scrap into crude steel by reducing carbon content and removing further impurities. : Limestone acts as a flux, combining with
Once the crude steel is produced, it undergoes to achieve precise chemical specifications. : Limestone acts as a flux
