  • Patent number: 8893768
    Abstract: 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.

  • Publication number: 20140008032
    Abstract: A composite side dam for a continuous twin roll caster includes a substrate made of a refractory material capable of withstanding casting temperature and having edge portions adapted to engage casting rolls and having a nip portion adjacent a nip between casting rolls and upper portions extending across the side dam to form a lateral restraint for a casting pool, an insert of at least 10 mm in thickness positioned in a pocket in the substrate and extending to engage the molten metal and extending from the upper portions of the substrate and positioned in the pocket to within 30 mm from the nip portion by insertion adjacent the upper portions of the substrate, and the insert adapted to fit into the pocket of the substrate to form a side dam formed of a refractory material having consumption rate less than 10 mm per hour. The material forming the insert may be between 40 and 60% SiAlON material and the remainder hBN material, or mullite material as described by FIG.

  • Patent number: 7975756
    Abstract: 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.
