Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...
Iron ore fines are the principal iron source for steelmakers, but without such agglomeration they would be difficult to charge to the blast furnace and, in the large volumes required, would form a dense impermeable mass once inside the furnace, seriously affecting the efficiency of the ironmaking process.

Iron ore from five hills contains more than 67.0% Fe. This is regarded as high-grade iron ore and compares well with other iron ores from the main iron ore producing nations. The silica and alumina contents of these ores are also below 1.2% and 1.0%, respectively, with correspondingly low levels of S (<0.006%) and P (<0.05%).
In terms of size, we usually meet the "iron ore fines" with a granular size of up to 10mm and the "iron ore lumps" with a size larger than 10mm. In terms of quality, the main parameter is its ferrous content which is expressed as percentage of the total ore and we see iron ore with Fe content which varies from hematite (high grade ore ...

Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is ...
Volume at full utilization, allowing for the maintenance of equipment and reflecting current material constraints. ... The process reduces iron ore fines with gas in a descending series of fluidized bed reactors. The reduced iron is hot briquetted. Finish. The surface appearance of steel after final treatment. Finishing Facilities.
Laying procedure. A trench of about 1.5 meters deep and 45 cm wide is dug. Then the trench is covered with a 10 cm thick layer of fine sand. The cable is laid over the sand bed. The sand bed protects the cable from the moisture from the ground. Then the laid cable is again covered with a layer of sand of about 10 cm thick.
