What is hot rolled sheet?
hot rolled sheet why? It is estimated that the inventor of hot rolling is Leonardo Da Vinci. It is known that Leonardo Da Vinci has drawings related to it. But it is known that it was first established in England in 1590 to produce steel bars upon the demand for Belgian iron. In order to obtain flat products, the first rolling plant was established in 1670, a plant called Pontypool plates in England. The aim was to produce sheet metal in order to make thin tin cans, that is, canned packaging.
HOT ROLLED STEEL
As the name suggests, "hot rolled steel" refers to the process of rolling steel by forming the steel by heating. Steel is exposed to high temperatures above 540 °C, which is above the recrystallization temperature. This heating process facilitates the processing of the steel. Moreover, hot rolled sheet Compared with cold rolled, the durability of hot rolled steel is less than cold rolled.
After the hot rolling process, the steel is left to cool at room temperature. Cooling with water after hot rolling will cause the steel to harden and stretch. This situation causes internal and external fracture of the steel.
hot rolled sheet They are easy to handle and soft. They can be used in various ways with their easy welding feature. Steel construction is also a good choice for fabricating structural steels such as metal beams and Train track tracks.
