How is Steel Manufactured

Steel is a metal that has been used for centuries in a variety of applications. It is strong, durable, and easy to work with, making it the perfect choice for everything from cooking utensils to skyscrapers. But how is steel manufactured? The following is a general overview of how steel is manufactured:

1) Iron ore is mined from the earth and transported to a steel mill.

2) The iron ore is first processed to remove impurities and create a concentrate of iron oxide.

3) The concentrate is then mixed with coke (a form of coal) and limestone in a blast furnace. Coke provides the carbon needed to reduce the iron oxide to iron, while the limestone helps remove impurities.

4) The blast furnace operates at very high temperatures (around 1,500°C) and creates molten iron that is tapped off and transported to a steelmaking facility.

5) In the steelmaking facility, the molten iron is combined with scrap steel and other elements (such as manganese, nickel, and chromium) to create a steel alloy with specific properties.

6) The steel is then cast into various shapes (such as ingots, billets, or slabs) and sent to be further processed into finished products, such as steel plates, bars, rods, or coils.
