Billets are produced through three processes: first, they are directly cast into billets from molten steel through the continuous casting equipment of the steelmaking system; The second is the semi-finished products of steel produced by the steel making system through the rolling equipment of the steel rolling system; Third, semi-finished products of steel ingots produced by the steelmaking system are processed by forging equipment.

Billet is the product of molten steel made by steelmaking furnace after casting. The steel billets can be mainly divided into two types from the manufacturing process: mold casting billets and continuous casting billets. The mold casting process has been basically eliminated. Billets are originally steel. After processing, they can be used as machine parts, forgings, and various steels. Q345B channel steel is a section steel, and wire rod is the role of billets.
