Casting of Clad Strip by a Twin Roll Caster

Abstract:

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.
