Reduction Kinetics of iron ore pellets and effect of binders

The iron ore was crushed, ground and screened to 100# size and charcoal to 72# size. Pellets were made by hand rolling method by using water and different quantities of binder. The pellets were fired at 1300ºC. Each crucible containing iron ore pellets were placed in a furnace and reduction was carried out at different temperature from 900-1050°C

For example, in blast furnace iron making, Fig. 5.1, iron oxide in the form of lumpy ore, sinter or pellet along with coke and limestone, are charged on the top of the furnace continuously. The charge slowly moves down and hot reducing gases produced by burning of coke in front of tuyeres move up through the bed of solids and finally escape through the gas outlet. The heat is transferred from ...

chemical reactions during iron ore pelletization

Direct reduced iron Wikipedia. Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 ...

2020-03-23  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 2. In the ideal situation, iron-bearing materials ...
