Modelling of twin‐roll strip casting processes

Communications in Numerical Methods in Engineering, 2003
AbstractIn this work, a twin‐roll strip casting industrial process is analysed using a fixed‐mesh finite element formulation able to deal with unsteady incompressible thermally coupled flows including phase‐change and non‐Newtonian effects assumed to account for the flow behaviour during the whole cooling conditions.

A novel approach to improve the macro-segregation defect and mechanical properties of Al–Mg–Mn aluminum alloys during twin-roll continuous casting

Journal of Materials Research and Technology, 2023
In this paper, the microstructure and properties of Al–Mg–Mn alloy slabs with different thicknesses by twin-roll continuous casting were investigated. Under the twin-roll continuous casting process, the alloy melt conducts directional crystallization due

Effect of melt conditioning on heat treatment and mechanical properties of AZ31 alloy strips produced by twin roll casting [PDF]

, 2014
In the present investigation, magnesium strips were produced by twin roll casting (TRC) and melt conditioned twin roll casting (MC-TRC) processes. Detailed optical microscopy studies were carried out on as-cast and homogenized TRC and MC-TRC strips.

Corrosion of twin belt and twin roll cast AlMg3Mn alloys

Corrosion Engineering, Science and Technology, 2013
Corrosion of twin belt and twin roll cast AlMg3Mn sheet samples was investigated. The AlMg3Mn sheet samples submitted to immersion tests undergo alkaline pitting around Al–Fe and αc-Al(Fe,Mn)Si intermetallic particles in the twin roll and twin belt cast samples respectively.

A novel research on the solute redistribution phenomenon of sub-rapid twin-roll cast Al-50 wt.% alloy treated by semi-solid heat treatment

Journal of Materials Research and Technology, 2021
In this study, a vertical twin-roll cast (TRC) thermal-fluid coupling model was established to determine a suitable roll-casting velocity. A slab of 0.9 mm thick roll-cast Al-50 wt.% Si alloy with a two-phase zone width of 473 °C was prepared at a ...

Sandwich Rolling of Twin-roll Cast Aluminium-steel Clad Strips

Procedia Engineering, 2014
In the present study experimental results of twin-roll cast aluminium-steel clad strips of a thickness of 2.0 mm using the example of pure aluminium and an austenitic steel are presented. Electron probe measurements of the bonding area revealed the presence of a continuous interface layer of about 2 μm.

Phosphorus Segregation in Meta-Rapidly Solidified Carbon Steels

High Temperature Materials and Processes, 2017
Twin-roll strip casters for near-net-shape manufacture of steels have received increased attention in the steel industry. Although negative segregation of phosphorus occurred in twin-roll strip casting (TRSC) steels in our prior work, its mechanism is ...
