Section Steel Mill

Description
A steel mill or steelworks as an industrial plant is mainly used for manufacturing steels. Section steel production line can produce Usteel, cap shaped steel, Cpurlin and other steels. The rolling plate in certain width is unfolded and leveled. Then, they are sent into the forming machine. The steel plate is bent to the needed form in the cold conditions by using the roller.

Brief Introduction of Steel
Steel is an alloy of iron and carbon. It is produced in a twostage process. First, iron ore is reduced or smelted with coke and limestone in a blast furnace, producing molten iron which is either cast into pig iron or carried to the next stage as molten iron. In the second stage, known as steelmaking, impurities such as sulfur, phosphorus, and excess carbon are removed and alloying elements such as manganese, nickel, chromium and vanadium are added to produce the exact steel required. Steel mills then turn molten steel into blooms, ingots, slabs and sheet through casting, hot rolling and cold rolling.

Application
1. Section steel production line can produce the different sizes of steel sheet piling used in the tunnel construction and foundation construction field.
2. Cold roll forming steel mill is used to roll and form cold and hot rolling steels into all kinds of open coldforming sectional steel like Cshaped steel, Ushaped steel, Lshaped steel and guard fence plates of freeway.

Features
1. Section steel production line has the advantages of excellent cold formability, welding ability, strip flatness and close dimensional tolerance.
2. Cold roll forming steel mill created many innovations in the pile industry such as wider, deeper and multiple thickness sections.
