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 &#x3bc;m during casting.

Method of thin strip casting

A method of continuously casting metal strip having the steps of assembling a pair of counter-rotatable casting rolls, assembling a metal delivery system adapted to deliver molten metal above the nip to form a casting pool, the casting pool forming a meniscus with each casting surface of the casting rolls, delivering a shell thickness controlling gas to select areas within 300 mm of end portions of at least one casting roll downwardly toward the meniscus between the casting pool and the casting surface adapted to control thickness of the metal shell, and control attenuation of the casting roll, and sensing the temperature and thickness profiles of the cast strip downstream from the nip to determine high or low temperature areas of the cast strip within 300 mm of the end portions and causing the gas to be delivered to the high or low temperature areas to change the thickness of the metal shell.

Method of continuous casting thin steel strip

The method of producing thin cast strip by continuous casting having a side dam assembly. The side dam assembly includes a side dam having opposite outer surfaces, one surface contacting molten metal and the opposite outer surface having fastening portions capable of attaching the side dam to a side dam holder, to hold the side dam in place during casting without exposed portions of the side dam holder extending substantially beyond the opposite outer surface toward the outer surface for contacting molten metal.
