Outline the general approach for the metallurgy of iron into steel The early application of iron to the manufacture of tools and weapons was possible because of the wide distribution of iron ores and the ease with which iron compounds in the ores could be reduced by carbon For a long time charcoal was the form of carbon used in the reduction process The production and use …
· Direct reduced iron DRI process In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the so called direct reduced iron DRI process secondary route The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore coke and lime which are fed into a blast furnace to produce molten iron The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel The electric arc furnace melts recycled steel scrap The molten steel is formulated to …
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 they need to be eradicated Step 2 does exactly this Step 2 Primary steel …
Steel exhibits a wide range of mechanical properties depending upon its composition and heating cooling cycles Heat treatment • Iron ore contains Fe2O3 along with gangue materials such as SiO2 Al2O3 • Charge materials are Iron ore limestone flux Coke • Output is pig iron 1300 C % C % Si % P % S % Mn Slag CaO/SiO2 = …
Scrap based steel production also referred to as secondary or recycled production can be valuable in reducing energy demand and CO2 emissions as it is considerably less energy intensive than primary production from iron ore Scrap is used as the main ferrous feed in electric arc furnaces EAFs as well as in induction furnaces to a lesser extent Scrap based …
