  • Iron ore pelletizing

    This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine ...

    of iron ore, using an integrated steel manufacturing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is converted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace (EAF) from scrap steel and, in some cases, from direct reduced iron. BOF is typically used for high ...

  • How to Convert Pig Iron Into Steel | eHow

    It is formed when iron ore is refined in a furnace in the presence of charcoal, limestone and air. It is the basic form of iron used to make decorative wrought iron items. When the pig iron is further refined and a minimum amount of carbon is added, the crystalline structure of the metal changes and steel is produced. Though possible to create ...

  • Steel production: from iron ore to functional industrial ...

     · How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The orebased process uses a blast furnace or smelter and the scrapbased process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

  • Optimization of the Iron Ore Direct Reduction Process ...

    Iron ore direct reduction is an attractive alternative steelmaking process in the context of greenhouse gas mitigation. To simulate the process and explore possible optimization, we developed a systemic, multiscale process model. The reduction of the iron ore pellets is described using a specific grain model, reflecting the transformations from hematite to iron.

  • Hydrogen as a Clean Alternative in the Iron and Steel ...

     · The carbon emissions are directly related to iron ore reduction, a process that produces usable pig (crude) iron to be turned into crude steel. Traditional iron ore reduction utilizes a chemical reaction between iron oxide and carbon monoxide sourced from heating coke fuel in a blast furnace. Coke is a hard, porous, nearly pure carbon product made by heating coal in the absence of air (in .

  • Production

    To make iron from the ore, it is reduced and melted in a blast furnace with coke at over 1300°C. The resulting pig iron contains more than 2% carbon and cannot be used for products in this form. It is only through the LD process that the pig iron is converted into steel by blowing it with pure oxygen.
