Question:

How is steel manufactured?

I need help! Please help, I'm in Chemistry, and me and my friend Lucy are making a presentation on steel and iron, so how is steel manufactured? Thank you. :D

Answer:

Abed is off on some of the details... Steel is, by definition, Fe-C. There are thousands of different steel alloys and I am not aware of a single one that is simpkly Fe-Ag. There are different processes but the chemistry is basically the same, converting the iron compounds we dig out of the ground into metallic iron. Iron is typically found as iron oxides or iron sulfides (not with a lot of carbon). We add carbon so the carbon takes the oxygen from the Fe atoms making Fe + CO/CO2. Research iron smelting, iron ore, reduction of iron oxide, these types of things. You will find plenty of information because this is one of the most important industrial processes humans have. Good luck
The steel consists of ( Iron ) and another matter... but the popular one is iron+carbon / iron+silver - When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. Approximately 96% of steel is continuously cast, while only 4% is produced as cast steel ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steel's final rolling it is heat treated for strength, however this is relatively rare.
