Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is foun
As a conclusion: the higher the PCI rate, the more char is formed, the lower the "consumable" nut coke rate. At a PCI level of 200 kg/tHM, the direct reduction has to consume 60 kg char and about 55 kg coke. The voidage available for draining the liquid ("primary") slag increases...
