Steel Plate Manufacturing Process

Steel plates are made through a complex process. First, iron ore is mined from the earth. This iron ore is then transported to a steel mill. At the mill, the iron ore is crushed into a fine powder. It is then mixed with other substances like limestone and coke in a blast furnace.

The blast furnace heats the mixture to an extremely high temperature. This causes a chemical reaction where the iron ore is reduced to molten iron. The limestone helps to remove impurities from the iron. once the molten iron is obtained, it is transferred to a basic oxygen furnace or an electric arc furnace for further refinement.

In the secondary furnace, more impurities are removed, and the composition of the steel can be adjusted by adding elements such as manganese, chromium, or nickel. After the refinement process, the molten steel is poured into a continuous casting machine. This machine forms the molten steel into a slab or a billet, which is the shape that will eventually be turned into a steel plate.

The slab or billet is then reheated and passed through a series of rollers in a rolling mill. These rollers gradually flatten and shape the steel into the desired thickness of the plate. After rolling, the steel plate may undergo additional processes such as heat treatment to improve its mechanical properties, cutting to the required size, and surface finishing to make it smooth and ready for use.

Steel plates are used in a wide variety of applications, from construction of buildings and bridges to manufacturing of ships and automobiles.

Question 1: What are the main substances mixed with iron ore in the blast furnace during the making of steel plates?
Answer: In the blast furnace during the making of steel plates, the main substances mixed with iron ore are limestone and coke.

Question 2: Why is the slab or billet reheated in the process of making steel plates?
Answer: The slab or billet is reheated in the process of making steel plates so that it can be passed through a series of rollers in a rolling mill more easily to be flattened and shaped into the desired thickness of the plate.
