Introduction to Iron ore Pellets and Pelletizing processes

The various advantages of iron ore pellets are given below Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production Pellets have good reducibility since they have high porosity (25 % to 30 %) Get price

Image

Creating Steel

Another way to create steel from pig iron is the Bessemer process which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter The heat of oxidation raises the temperature and keeps the iron molten As the air passes through the molten pig iron impurities unite with the oxygen to form oxides Get price

Image

How steel is made

To make steel iron ore is first mined from the ground It is then smelted in blast furnaces where the impurities are removed and carbon is added In fact a very simple definition of steel is iron alloyed with carbon usually less than 1% The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I Get price

Image

How we make steel

The ingredients – iron ore coke and limestone fines – are carefully stacked and blended then passed under an ignition hood at the sinter plant This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces Making ironGet price

Image

Iron Ore Pelletizing Process An Overview

The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countries However the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing process Get price

Image

Iron Production

The iron found in iron ores are found in the form of iron oxides As a result of these impurities iron must be first separated from the gangue and then converted to pure iron This is accomplished by the method of pyrometallurgy a high temperature process The high temperatures are needed for the reduction of iron and the oxidation of the Get price
