The status of twin‐roll casting technology
Scandinavian Journal of Metallurgy, 2003Within the coming days the world's first commercial, direct twin‐roll caster for carbon steel strip less than 2.0 mm, without further hot or cold rolling, will be started by Nucor in the United States. Although the process has been previously proven on a technical basis during full‐scale development in Australia, the Nucor caster is unique in that it ...

Analysis of Casting Roll Temperature Field during Twin-Roll Thin Strip Casting
Advanced Materials Research, 2008In twin-roll strip casting process, the temperature variation of casting roll can result in roll thermal stress and fatigue. It not only affects the thermal deformation of casting roll and the generation of the roll surface cracks significantly, but also influences the surface quality, shape and profile of the produced strip, and the service life of ...

Influence of Temperature and Rolling Speed on Twin Roll Cast Strip
2013Reducing vehicle weight and emissions by lightweight design is a major goal of the automotive industry. Magnesium as the lightest structural metal offers a significant weight saving potential compared to steel and aluminum. Cast magnesium components are widely used, e.g. as engine blocks or gear box housings.

Design of a composite roll for twin-roll casting of Mg-AZ31
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2016In twin-roll casting, as heat is transferred from melt to rolls, the melt is cooled, solidified and finally rolled to a specific thickness. Therefore, an efficient cooling system for the roll is very important for a stable operation of the process. In the present study, a composite roll with internal cooling channels was designed for twin-roll casting ...

Twin-roll casting with an electromagnetic edge dam
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002Twin-roll casting is an old process that was first proposed by Bessemer. Over the years one of the main problems preventing its development has been edge containment of the liquid metal pool between the rolls. Ceramic dams pressed up against the rolls have been used with some success. However, ceramic dams have the problems of requiring a super heat to

Water Modeling of Twin-Roll Strip Casting
Journal of Iron and Steel Research International, 2006Twin-roll strip casting is regarded as a prospective technology of near net shape continuous casting. The fluid flow field and level fluctuation in the pool have a strong influence not only on composition and temperature homogeneity of pool, but also on the strip quality.

Casting of Clad Strip by a Twin Roll Caster
Materials Science Forum, 2014Clad strip consisting of 5182 aluminum alloy and other aluminum alloys could be cast using a twin roll caster equipped with a scraper. This twin roll caster could carry out the strip casting and the bonding of the strips. The equipment, that was developed to prevent the contact between the bonding surface of the strip and oxidizing environment, was ...

A Review of Numerical Models for Twin-Roll Casting
Advanced Materials Research, 2014Converting the viscosity of an incompressible nonlinear viscous fluid to the proportional constant of the flow rule of Mises material, the melt, the mushy state, and the solidified in twin-roll casting were able to be regarded as an incompressible nonlinear thermo-viscous material.
