Billet refers to semi-finished products used to produce steel, which cannot be directly used by society. After processing, it can be used as mechanical parts, forgings and various steels, such as section steel Q345B channel steel, and the wire is used as billet.
There are three technological methods for billet production, that is, continuous casting equipment in steelmaking system directly casts from molten steel, rolling equipment in rolling system processes semi-finished steel, and ingots produced in steelmaking system process semi-finished steel with forging equipment.
