Abstract
Iron ore pellets reduced with hydrogen were isothermally carburized in CH4H2N2 at 823 K 923 K and 1023 K 550 °C 650 °C and 750 °C Temperature strongly affected the total carbon concentration after carburization significant unbound carbon deposited at the highest temperature For the range of sizes tested 10 to 12 mm pellet size did not affect carburization The variability between pellets was much smaller than for industrial pellets inhomogeneous gas distribution likely affects carburization under largescale industrial conditions
