Continuous casting is a manufacturing process that allows metals and metal alloys to be shaped then solidified without interruption. Metal is poured into a mold and rapidly chilled to ensure a uniform grain structure within the metal. Most often, these shapes are tubes and solids, but can also include squares, rectangles, and other irregular ...
Flextreme™ is Novelis' proprietary technology for continuous horizontal casting of ready-to-forge aluminum billets.

In 1970, after Duwez's seminal discoveries, a twin-roll casting (TRC) technique for preparing uniform films of metastable phases was devised by Chen and Miller . To date, this technique in producing metallic glass ribbons is still almost limited to laboratory scale studies [16,17,18,19,20,21,22]. It turns out that TRC is an available …
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.

What is Continuous Casting and Continuous Rolling? After the molten steel produced by the converter is refined in the refining furnace, the molten steel needs to be cast into billets of different types and specifications. The continuous casting section is a production process in which the refined molten steel is continuously cast into a billet.
