As-Cast Microstructure and Texture of Twin-Roll Cast AZ31
2014In this study, the microstructure and texture of twin roll cast (TRC) AZ31 (Mg-3wt.%Al-1wt.%Zn) alloy has been investigated. The structure of the as-cast TRC AZ31 was dendritic containing both columnar and equiaxed grains. Second phase particles, Al-Mn and Mg-Al-Zn, were distributed evenly in matrix.

Computational Fluid Dynamics Applied to Twin-Roll Casting
Canadian Metallurgical Quarterly, 1998Abstract Near-net-shape casting technology is one of the most important research areas in the iron and steel industry today. Driving forces for the development of this technology include a reduction in the number of operations needed for conventionally produced strip. This is especially true of hot rolling operations.

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.

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 ...

Modeling of solidification in twin-roll strip casting
Journal of Materials Processing Technology, 2000Abstract Twin-roll continuous casting combines solidification and hot rolling into a single operation to produce thin strips that are directly coilable. It offers advantages of low capital investment and low operational cost, and the strips produced have a refined solidification microstructure, which has attracted interest of global metal producers ...

A twin-roll caster to cast clad strip
Journal of Materials Processing Technology, 2003Abstract A single-roll caster and two kinds of twin-roll casters to cast clad strips were designed and assembled. One of twin-roll casters was suitable for clad strip casting. This twin-roll caster can cast clad strips of aluminum alloys at the speed of 20 m/min. The thickness of the clad strip is about 2.0 mm.

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.
