An Experimental Investigation of the Effect of Strip Thickness, Metallostatic Head and Tip Setback on the Productivity of a Twin-roll Caster

Abstract

An experimental study has been made of the factors affecting productivity during the twin-roll casting of AA 5182. Strip has been cast over a much wider range of thicknesses and tip setbacks than previously reported. An empirical expression is obtained which relates productivity to strip thickness, metallostatic head and tip setback. It is shown that productivities can be considerably increased over the usual commercial practice by casting thin sheet with large tip setbacks.
