Beam-blank casting results in fewer passes in the section mill, reduced energy use and lower production costs. Near-net-shape casting is an energy-saving alternative to conventional bloom casting for the production of beams and sections. The greatest benefits can be derived through the direct coupling of the caster to the rolling mill.

In a steel mill, steel is cast by a continuous caster into raw building materials. Continuous casters create standardized raw steel shapes rather than near-finished parts. Raw steel will be machined or worked into final products. Steel mills commonly cast and form sheets, billets, bars, blooms, pipes, ingots, and wires.
