Semi-finished casting products

Common final products include structural shapes, rails, rods, and seamless pipes.

Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom.

[3] Centrifugal casting is also used to produce short circular tubes as billets, usually to achieve a precise metallurgical structure.

They are commonly used as cylinder sleeves where the inner and outer diameters are ground and machined to length.

One of the reasons to preferably produce slab through BF route is to achieve high quality.
