SOUND WAVES APPLIED TO CASTING POOL OF METAL STRIP CASTING APPARATUS FOR INCREASED COOLING RATE AND REFINED SURFACE STRUCTURE OF CASTING METAL

摘要

A method and an apparatus of continuously casting metal strip (20) is disclosed. A casting pool (30) of molten metal is formed in contact with a moving casting surface such that metal solidifies from the pool (30) onto the moving casting surface. In addition, sound waves are applied to the casting pool of molten metal to induce relative vibratory movement between the molten metal of the casting pool (30) and the casting surface.
