The Modern Steel Manufacturing Process The Balance

Jan 14, 2020 The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal andget price

The 6 Steps To Modern Steel Production Explained Metro Steel

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.
