Abstract:
In twin-roll casting, the melt is cooled, solidified and rolled to a specific thickness only by the rolls and consequently a lot of heat is transferred from the melt to the rolls through the melt/roll interface. In a composite roll, consisting of a steel core and a copper-alloy sleeve, the heat is finally removed by cooling water flowing through internal cooling channels. In the present study, design of the channels was improved using finite-element analysis in the aspects of structural as well as fatigue strengths.

Abstract:
Thermal flow finite element simulation was carried out to deeply understand the solidification and deformation phenomena of magnesium alloy in molten zone during twin-roll casting process. The results show that temperature near the nip of the rolls is about 680K based on current conditions, and there are two vortexes in the molten pool during casting, a peak formed at solidus. Due to the metal flows in molten pool and relative rotates of the rolls, temperature field of molten zone is different from normal casting, which will cause the solidification structure changes.

Abstract:
Two main impediments are currenty discussed with respect to the industrial application of magnesium sheets. First, the low formability of magnesium sheets requires many rolling passes to roll cast slabs to final gauge, which leads, second, to high costs for the production of magnesium sheets. An alternative cost-saving process chain for magnesium sheets with enhanced properties is the feedstock production by twin roll casting (TRC). In the TRC process, liquid metal proceeds from a furnace over a pipe into a crucible and then flows between a pair of counter rotating, internally cooled rolls. Th

Abstract:
Production of aluminum alloy clad strips requires many processes, and a reduction in the number of processes has long been demanded. A method to cast clad strips directly from molten metal using a twin roll caster with copper rolls is proposed in this work. Two types of twin roll casters were designed and tested. One was a vertical-type tandem twin roll caster and the other was a twin roll caster equipped with a scraper. The casting of the clad strips was conducted in an oxidizing atmosphere. The clad strips were cast at speeds higher than 15 m/min. This casting speed is much higher than that

Abstract:
The disadvantages of the conventional twin-roll caster for aluminum alloy are low casting speeds and limited choices of alloys that are castable by this processing. It is known that strip casting of aluminum alloy 5182 is very difficult because of their wider freezing zones. The vertical-type high-speed twin-roll caster used in the present study was devised to overcome these disadvantages. Features of the high speed twin roll casters are as below. Mild steel rolls were used in order to increase the casting speed and to be made at a lower equipment cost. Roll coating is produced in casting of A

Increasing use of aluminum alloys in the automotive industry increases the importance of the production of sheet aluminum. To provide cost effective sheet aluminum to the industry, twin-roll casting (TRC) is becoming more important compared to DC casting. Demand for usage of different aluminum alloys in sheet form introduces some difficulties that should be considered during their applications. The main problem encountered during the welding of aluminum alloys is hot cracking.
