Step 1 The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% % impurities such as carbon which in turn make the metal brittle ...

13. Driving Force for Sintering As with all processes, sintering is accompanied by an increase in the free energy of the system. The sources that give rise to the amount of free energy are commonly referred to as the driving forces for sintering. The main possible driving forces are The curvature of the particle surfaces An externally applied pressure A chemical reaction

To make steel, impurities in the iron ore like, sulphur, silica, phosphorous, lime, etc. needs to be removed. It is done through the following process(a) During the iron making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes such as limestone. (b) This slag floats on the molten iron and is collected at ...

The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.

The steel industry contributes around 8% of the world's carbon emissions and is largely (73%) reliant on blast furnace and basic oxygen furnace (BOF) technologies to separate oxygen from the iron oxides that make up iron ore and produce the strong, permanent material known as steel. Making steel involves several applications of extreme heat.
