Twin Roll Casting and Melt Conditioned Twin-Roll Casting of Magnesium
Solid State Phenomena, 2008Recently, BCAST at Brunel University has developed a MCAST (melt conditioning by advanced shear technology) process for conditioning liquid metal at temperature either above or bellow the alloy liquidus using a high shear twin-screw mechanism. The MCAST process has now been combined with the twin roll casting (TRC) process to form an innovative ...

Study on Casting Roll during Twin-Roll Casting of Thin Strip
Materials Science Forum, 2010In twin-roll thin strip casting, the temperature of casting roll affects the roll thermal stress, and influences the thermal deformation, the generation of roll surface cracks, the strip shape and the service life of casting roll. In this paper, the features of the casting roll materials have been analysed, the effects of the clad materials and ...

Research on Cast-Rolling Model in Twin-Roll Continuous Strip Casting
2009 International Conference on Measuring Technology and Mechatronics Automation, 2009Combining classic rolling and casting theory and finite element method(FEM), a rolling force controlling model has been deduced in twin-roll strip casting, which considers the influence of casting velocity and melt level. After accuracy certification, the model has high precision under given conditions, and it can be used to set initial parameters ...

Development of the twin-roll casting process
Journal of Materials Processing Technology, 1995Abstract Twin-roll casting has been used for approximately 40 years for the production of aluminium strip. Traditionally, the process has been one of low productivity and has been restricted to a limited range of alloys and a minimum cast thickness of approximately 6 mm.

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.

Research on the Rolling of AZ31 Strip Prepared by Twin Roll Casting
Materials Science Forum, 2009The AZ31 thin sheet (minimum thickness less than 1mm) was obtained by rolling the cast strip which was prepared by vertical twin roll casting in this paper. Since the absolute deformation during rolling was smaller,due to the small thickness of the strip of 3mm, the rolling of cast strip was different from the conventional rolling process. It was found

Analysis of Thermal Stress and Deformation of Casting Roll in Twin Roll Strip Casting Process
Transactions of the Korean Society of Mechanical Engineers A, 2002The casting roll design is one of the most important requirements in twin roll strip casting process. Coupled analyses of heat transfer and deformation for the cast roll are carried out by use of the finite element program MARC to examine the thermal stress and deformation.
