Sticking of iron ore pellets in direct reduction with hydrogen and carbon monoxide: Behavior and preventionYI Ling-yun(易凌云), HUANG Zhu-cheng(黄柱成), LI Tie-hui(李铁辉), JIANG Tao(姜涛) (School of Minerals.... The results show that the sticking strength of the pellets increases with temperature, however, decreases with hydrogen content in reducing gas. For an efficient shaft furnace operation in direct reduction (DR......
