Plate Steel Making Process

Plate steel is made through a series of complex processes. First of all, iron ore is mined from the earth. This iron ore is usually in the form of oxides. Then, the iron ore is transported to a steel mill.

At the steel mill, the iron ore is smelted in a blast furnace. In the blast furnace, coke (a form of carbon) is used as a fuel. The coke burns and provides the heat necessary to reduce the iron ore to molten iron. Limestone is also added to the blast furnace. It helps to remove impurities from the iron ore.

once the molten iron is obtained, it is further refined in a basic oxygen furnace or an electric arc furnace. In the basic oxygen furnace, oxygen is blown into the molten iron to burn off impurities such as carbon, sulfur, and phosphorus. The electric arc furnace uses electric arcs to melt scrap steel and other raw materials, and also to refine the steel.

After refining, the molten steel is poured into a continuous caster. The continuous caster forms the molten steel into slabs or billets. These slabs or billets are then rolled in a rolling mill to form plate steel. The rolling process reduces the thickness of the steel and gives it the desired shape and properties.

Finally, the plate steel may go through additional processes such as heat treatment, cutting, and surface finishing to meet the specific requirements of different applications.

Question 1:

What are the main raw materials in making plate steel?

The main raw materials in making plate steel are iron ore, coke, and limestone. Scrap steel can also be an important raw material when an electric arc furnace is used.

Question 2:

Which furnace is used to refine the molten iron in making plate steel?

Either a basic oxygen furnace or an electric arc furnace can be used to refine the molten iron in making plate steel.
