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. The special mold-taper design from Primetals Technologies offers a large operating window with respect to varying casting speeds and different steel grades. High-quality structural beams can be produced with a broad range of product dimensions.
In the last years, Primetals Technologies has developed and implemented near-net-shape beam blank casters and special designed combi-caster for long products, which offer the operator highest flexibility with respect to different casting sections and market demands. It is possible to combine the production of billet, bloom and near-net-shape beam blank at one single casting machine. An optimization for beam blank casting has been reached with latest developments in the equipment design and in the fine tuned mold tapers and spray cooling. Primetals Technologies beam blank casters provide high productivity combined with direct hot charging to the rolling mill. Near net shape beam blank casting is an excellent alternative to the more conventional bloom casting route for the production of small to jumbo H-beams and profile shapes.
