A single roll caster equipped with a scraper was proposed, designed and assembled. Properties of this caster and of the strip cast by this caster were investigated. 5182 aluminum alloy was cast into the strip. This caster could cast the strip at the speeds ranging from 20m/min to 40m/min. Strip thickness could be controlled by the roll speed and the solidification length. The as-cast strip was free from center-segregation and inside-micro-porosity. The as-cast strip could be cold rolled down to 1mm. There was no difference between the roll contact surface and scribed surface of the cold rolled strip. The mechanical property of the strip cast by this caster was as almost same as the strip made by D.C. casting and hot rolling process.
