Reduction of Edge-Bur of Strip Cast Using a High Speed Twin Roll for Light Metal

Abstract

Burr changer was proposed to change vertical burr to horizontal burr. The burr changer was attached to inside of a side dam plate. Lower edge position of the burr changer was the most important factor to change the vertical burr to the horizontal burr. A383 aluminum alloy was cast at roll speeds of 30 and 60 m/min. There was not difference between the strip and horizontal burr after cold rolling and annealing.
