Steel Manufacturing Process. To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make steel. Modernday steelmaking is highly improved and specialized.

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.

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 ...

A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blastfurnace route. The first process of the route is the production of hydrogen by water electrolysis using CO2lean ...

Luis Verdeja. 2015. Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is studied and researched in the steelmaking industry in general, and ...

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.

The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.

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 ...
