• Two main types of DRI processes: Gas-based DRI and Coal-based DRI • Iron ore pellets, typically containing a mixture of iron oxide and other elements are prepared • Iron ore pellets undergo chemical reactions with reducing agent (natural gas or carbon from coal), resulting in the removal of oxygen to produce direct reduced iron in the lower part of the shaft • The DRI along with scrap steel, is then charged into the Electric Arc炉子•电力用于产生电弧,该电弧融化炉子中的DRI和废料钢•添加合金或其他添加剂以实现所需的钢组成•由于将化石能源用作还原剂和非可再生电力•目前通过Dri
