Casting of Al-25%Si Strip Using a Vertical Type Twin Roll Caster
Strip casting of Al-25%Si was tried using the vertical type high speed twin roll caster. Some devices were adopted to enable the strip casting of Al-25%Si. Control of the roll gap, semisolid casting and non-use of the lubricant were useful devices to cast Al-25%Si strip. Roll-casting-ability of the Al-25%Si was discussed. The strip could be cast at 20m/min and 40m/min. As-cast strip was hot rolled down to 1mm by one pass. Bulging was tried at 550°C and it was able.
