Based on the research on the solidification of twin-roll continuous casting aluminum alloy thin strip, the analytical model of heterogeneous nucleation, the growth kinetics of tip (KGT) of twin-roll continuous casting aluminum alloy thin strip solidification are established by means of the principle of metal solidification, meantime based on the cellular automaton, the emulational model of twin-roll continuous casting aluminum alloy thin strip solidification is established. The foundation for the emulational simulation of twin-roll continuous casting thin strip solidification structure is laid. Meanwhile has confirmed the mathematical simulation feasibility by using the solidification process of twin-roll continuous casting aluminum alloy Thin Strip.

Twin Roll

Clad 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 adopted. The developed equipment was a scraper. The 5182 strip could be bonded to other aluminum alloy strips by the effect of the scraper. Aluminum alloys for casting has poor formability, especially, bending ability is poor. The clad strip consisting of A356 casting aluminum alloy and 3003 wrought aluminum alloy was cast. 180 degree bending test was carried out on this clad strip. In the condition that the 3003 strip was outer side and A356 strip was inner side, the crack did not occur at the outer 3003 strip. In the deep drawing test or the clad strip, LDR (Limiting Drawing Ratio) was 1.8. These results mean that the casting aluminum alloy has ability to be used for the sheet forming, if the casting aluminum alloy is cladded with the wrought aluminum alloy.

Secondary Solidification

Rheo-die casting (RDC) based on LSPSF (low superheat pouring with a shear field) rheocasting process has been exploited. In case of secondary die casting aluminum alloy YL112, LSPSF allowed for preparation of sound semi-solid slurry in 15-20s that fully meet the production rate of HPDC, the primary α-Al exhibiting a mean equivalent diameter of 70 μm and shape factor of 0.93, without any entrapped eutectic. Compared to conventional HPDC, RDC improves microstructures in castings. Secondary solidification of semi-solid slurry takes place uniformly throughout the entire cavity, producing an extremely fine and uniform microstructure. The experimental results show the RDC 380 alloy has much improved integrity and mechanical properties, particularly elongation, and heat treatment can be used to enhance the mechanical properties.
