Abstract
An apparatus for continuous casting a metal strip and reducing snake eggs in the metal strip. A pair of counter rotating casting rolls through which a thin strip can be cast are provided. A metal delivery system is disposed above the nip for discharging molten metal into a casting pool supported on the rolls. A pair of side dam holders and a pair of side dams are assembled adjacent each end portion of the rolls. Each side dam holder is tapered and dovetails with an adjacent side dam to confine the casting pool of molten metal supported on casting surfaces of the rolls. An oscillation mechanism provides lateral oscillation to each side dam and side dam holder at a frequency 2-50 hertz and with an amplitude 100-2000 μm during casting.
