Steel billet is a product made by steel-making furnace by casting. The billet can be divided into two kinds from the manufacturing process, mould blank and continuous casting billet. At present, the casting process has been basically eliminated.classification
Mainly from the shape of two:Slab: the ratio of section width and height is larger, which is mainly used for rolling plate.Billet: cross section width, height equal, or difference is not big, mainly used for rolling steel, wire.Texture of materialContinuous casting square and rectangular billets are mainly made of plain carbon steel, low carbon and low silicon cold rolled material, high quality carbon structural steel, low alloy high strength steel, special steel and so on.
