Carbon Steel Billet Stainless Steel Billet
After processing, billets can be used as mechanical parts, forgings, processing various steels, section steel Q345B channel steel, and wire rods are the role of billets.
material:
Continuous cast steel round billets, square billets and rectangular billets are mainly represented by ordinary carbon steel, low-carbon and low-silicon cold-rolled material, high-quality carbon structural steel, low-alloy high-strength steel, and special steel grades.
Type of billet
Round billet: cylindrical, mainly used for rolling various steel pipes, including stainless steel and carbon steel billets.
Slab: The ratio of section width and height is large, and it is mainly used for rolling plates.
Billet: The width and height of the section are equal, or the difference is not large, and it is mainly used for rolling section steel and wire rod.

Billet production process
Billets are produced by three process methods:
First, through the continuous casting equipment of the steelmaking system, the molten steel is directly cast into the billet;
The second is the semi-finished steel products processed by the rolling equipment of the steel rolling system for the steel ingots or continuous casting billets produced by the steelmaking system;
The third is the semi-finished product processed by the forging equipment for the ingot produced by the steelmaking system.
