Reduction of Iron Ore Pellets, Sinter, and Lump Ore under

Mar 23, 2020 A blast furnace (BF) is the most common process for hot metal production in the world The BF is charged with metallurgical coke and iron‐bearing materials separately, which leads to a layered structure The iron‐bearing materials consist of iron ore pellets, lump ore, and sinter When the charge material descends, it is reduced by CO and H 2Sinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace Predominant source of iron in many blast furnace processes This technology was developed for the treatment of the waste fines in the early 20th centurySINTERING AND PELLETISATION OF INDIAN IRON ORESJun 13, 2014 Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden Uses of all the three metallics in blast furnace burden can vary from zero to hundred percent with adjustment of the furnace parametersUse of Iron Ore Pellets in Blast Furnace Burden – IspatGuruThe sinter of high basicity would interact with lump ores or acid pellets in the cohesive zone of blast furnace due to the difference of chemical composition and micro structures The results of this work showed that the softeningmelting properties of lump ores and acid pellet would be obviously improved by the high temperature interactionHigh Temperature Interaction between Sinter and Lump Ores Jul 26, 2020 The sinter slag is observed to control the melting and dripping properties of the mixed bedThese results gives an understanding of individual and (PDF) A comparative study of pellets, sinter and mixed
