    HYL Process for Direct Reduction of Iron Ore – IspatGuru. HYL process is designed for the conversion of iron ore (pellet/lump ore) into metallic iron, by the use of reducing gases in a solidgas moving bed reactor. Oxygen (O2) is removed from the iron ore by chemical reactions based on hydrogen (H2) and carbon monoxide (CO) for the production of highly metallized direct reduced iron (DRI ...

    Iron Ore Abundant, makes up 5% of earth's crust Is not found in 'free state', must be found in rocks and oxides, hence Iron ore. After mining, the ore is crushed and the iron is separated, then made into pellets, balls or briquettes using binders, such as water. The pellets are typically 65% iron, and about 1" in diameter.

    sinter/pellet plants and coke ovens are not only capital ... The FASTMET and LB processes use iron ore concentrate and pulverized coal as raw materials. The gasif iion of coal and prereduction of iron ore proceed in the same reactor. These processes present good kinetic conditions for chemical reactions due to large gas/solid interfacial area and short distances for reactant transport ...

    Direct reduced iron Wikipedia. Process Direct reduction processes can be divided roughly into two egories: gasbased, and coalbased 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 °C ...

    REDUCTION AND SWELLING BEHAVIOUR OF FIRED IRON ORE PELLETS

    The pellets fired at 13000C were processed for reduction and swelling studies in different types of coal. The degree of reduction of fired iron ore pellets increased with increase of reduction temperature and time up to the range studied. The extent of swelling in fired iron ore pellets during their production increased with increase of reduction time, most probably due to the structural ...

    Direct Reduced Iron and its Production Processes – IspatGuru

     · Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes. The reducing agents are carbon monoxide (CO) and hydrogen (H2), coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on .

    Iron And Steel Production

    Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the blast air to form molten reduced iron, carbon monoxide (CO), and slag. The molten iron and ...
