Popis: | The concentration and chemical bonding state of carbon in direct-reduced iron (DRI) might affect DRI melting temperature and rate. The effects of carbon bonding state and concentration were evaluated with high-temperature confocal microscopy, differential scanning calorimetry, and by monitoring the carbon monoxide generation rate from reaction between DRI pellets and a laboratory slag-steel melt. In industrial steelmaking, DRI melting is likely controlled by heat transfer; the concentration and bonding state of carbon play secondary roles. |
