Abstract: In a twin roll continuous caster, the casting nozzle in the continuous casting apparatus is arranged such that the outlet passages and/or tapered walls in the main portion within the casting nozzle provide flow of molten metal downwardly converging toward the nip between the casting rolls of a twin roll caster. The casting nozzle having a reservoir portion for directing molten metal converging toward the triple point region to inhibit the washing of shells forming on the casting surfaces of the casting rolls.

Abstract: A side dam for a continuous twin roll caster with a body of refractory material shaped to form a side dam and having edge portions adapted to engage end portions of casting rolls of a twin roll caster and having a nip portion adapted to be adjacent a nip between the casting rolls and having upper portions extending across the side dam to form a lateral restraint for a casting pool of molten metal during operation in the twin roll caster; and a pocket between 5 and 50 mm in depth formed in the body between the edge portions and forming shoulder portions in the body between the edge portions and the pocket adapted to be worn as a casting campaign continues until the pocket is reached and continuing to be worn away at level of base portions of the pocket until casting is completed.
