billet casting

Billet casting is a metallurgical process used in the continuous casting of steel. In this method, liquid steel is poured into a water-cooled copper mold, where it solidifies into a continuous strand. Billet casters specifically produce strands that are typically 80 to 175 millimeters square or round.1

These billets serve as the initial feedstock for creating long metal products with smaller cross-sections, such as bars and rods. If billets are not directly cast, they are further processed by rolling blooms in specialized billet mills. This process is a key part of metallurgy, the science of creating useful metal products, where casting involves pouring molten metal into a mold to solidify into a desired shape.23
