SMS Concast supplies highly versatile billet casters that enable rapid adaptation to changing market demands while raising both product quality and plant throughput. Billet casting covers small and medium square and rectangular sections, as well as round sections with comparable cross section, with typical dimensions between 85 mm and 200 mm. 

The continuous casting solutions accommodate a wide spectrum of steel grades, from basic construction steel and rebar to stainless steel for wire rod and bars enabling downstream products ranging from wire rods of approximately 5.5 mm up to bars of about 90 mm. 

SMS Concast develops bloom casting solutions tailored for applications demanding the highest metallurgical purity and flawless internal soundness. Where final products must perform without compromise, from ball bearing to stainless steel products, bloom sections provide the consistent chemical cleanliness and internal soundness required for premium markets.

SMS Concast’s bloom casting technology supports improved yield, tighter process control and higher throughput, paving the way for plants to enhance both the quality and volume of their high‑end steel products.

Beam blanks are near‑net‑shape products used to feed medium and heavy section mills. This state‑of‑the‑art casting technology was pioneered by SMS Concast. 

The Concast optimized mold tubes have a positive impact in reducing web‑crack formation. The wide range of beam blank sections of Concast casters requires completely new and individualized approaches to the design and dimensions of the molds as well as to the overall continuous‑casting equipment set‑up. 

Vertical continuous casting is the preferred alternative to curved bloom casters to replace ingot casting for the most demanding applications, where quality and cleanliness are of paramount importance, while still guaranteeing high production rates up to about 1,000,000 t/year. 

Vertical casting eliminates the need to straighten a curved, just-solidified strand into a horizontal direction: an operation that, depending on section size, caster radius and casting speed, induces high strain and stress in the strand shell and can cause surface or solidification‑interface cracks in critical grades. Vertical casting therefore eliminates the risk of bending/straightening‑related defects and provides superior conditions for the separation and distribution of non‑metallic inclusions in the mould.

The VERSCON semi‑continuous casting process adapts the established semi‑continuous practice used for non‑ferrous metals (aluminium, copper) to steel production, addressing the increased complexity deriving from steel’s slower solidification. The concept casts one or two ladles on one or more vertical strands into very long blooms using a conventional mould and oscillation table; once a strand reaches its final length, casting is stopped, and the strand is held in position until final solidification. Typical section diameters range from about 400 mm (1 t/m) up to around 1,400 mm (12 t/m), with round sections generally preferred.
