Question: How is steel made?
Name: Rakhodaei
Answer : Most steel is made via one of two basic routes:
Integrated (blast furnace and basic oxygen furnace).Electric arc furnace (EAF).
The integrated route uses raw materials (that is, iron ore, limestone and coke) and scrap to create steel. The EAF method uses scrap as its principal input.
The EAF method is much easier and faster since it only requires scrap steel. Recycled steel is introduced into a furnace and re-melted along with some other additions to produce the end product.
Steel can be produced by other methods such as open hearth. However, the amount of steel produced by these methods decreases every year.
