| 20090038771 | Casting Roll Moving Apparatus of Twin Roll Type Continuous Strip Casting Process - A casting roll moving apparatus for a twin roll type continuous strip casting process is disclosed. The casting roll moving apparatus is used with a twin roll type strip casting machine that produces a strip through a method in which, while high-temperature steel melt is supplied between twin rolls which rotate in opposite direction, a large amount of heat is dissipated through the rolls by contact between the steel melt and the rolls, so that the steel melt is rapidly solidified. Opposite ends of the rolls are automatically aligned, so that the recovery rate of the apparatus is increased, and a stable casting process is ensured. Because friction of the apparatus is markedly reduced so that an even rolling force is ensured, a gap between the rolls is maintained constant. Thus, the thickness of a cast strip is maintained constant, and the problem of the occurrence of an uneven surface pattern is solved. | 02-12-2009 |
| 20090090480 | METHOD AND APPARATUS FOR CASTING THIN CAST STRIP - Twin roll casters for casting thin steel strip comprise cooled casting rolls mounted on carriers. One roll is fixed and the other is moveable laterally and biased toward the other roll by carrier drive units acting on the moveable roll carriers. A casting pool of molten steel is supported on the rolls which are rotated to produce a solidified steel strip delivered downwardly from the nip therebetween. A gap is regulated between the rolls such that unsolidified molten metal passes through the nip between the solidified shells of the forming strip and solidifies below the nip. The carrier drive units are effective to apply to the biased roll substantially intermediate biasing forces such that the roll separation force at the casting rolls is regulated to a value between 2 and 4.5 Newtons per millimeter. | 04-09-2009 |

| 20090255644 | TWIN ROLL CASTER - A twin roll caster including chilled rolls, side weirs, and a molten-metal delivery nozzle. Baffles, contiguous with bottoms of end faces of the nozzle, project in a casting pool toward the side weirs to suppress stream of the molten metal into a nip between the rolls. Thus, hot molten metal just after poured into the pool does not instantly reach the nip along the side weirs, and molten metal decreases in temperature with lapse of time after the pouring streams into the nip as the rolls are rotated. As a result, belated formation of solidified shells at and adjacent to outer circumferential edges of the chilled rolls is eliminated. Thus, a strip delivered from the nip between the rolls has no reduced thickness at regions adjacent to lateral edges of the strip and has uniform thickness throughout the width of the strip. | 10-15-2009 |

Specifically, the cast-piece edges are generated by pressing and bonding lateral edges of one of solidified shells to lateral edges of the other solidified shells, the lateral edges of the solidified shells being produced by cooling and solidifying the molten metal on surfaces of collars provided at lateral end portions of the cooling rolls. The cast-piece central portion contains the unsolidified molten steel between the solidified shells and is generated by cooling and solidifying the molten steel on the surfaces of the laterally central portions of the cooling rolls. | 07-15-2010 |
| 20100243194 | Stationary side dam for continuous casting apparatus - Exemplary embodiments of the invention provide a side dam for a continuous metal casting apparatus having elongated opposed casting surfaces forming a casting cavity. The side dam has an elongated upstream part and an elongated downstream part that are mutually laterally pivotable, and a smooth metal-contacting side surface extending continuously from an upstream end to a downstream end of the side dam. The surface has regions thereof formed on the upstream part and the downstream part. Mutual pivoting of the upstream part and the downstream part of the side dam enables the regions of the smooth metal-contacting side surface to be moved out of mutual coplanar alignment. The side dams can therefore be used to form either a convergent or divergent casting cavity to assists the casting procedure and to enhance the properties of the cast article. | 09-30-2010 |

| 20120012273 | OPERATING METHOD FOR TWIN-ROLL CASTING MACHINE, AND SIDE WEIR SUPPORTING DEVICE - An operation to acquire a strip with less thickness even if arcuate worn steps are formed on side weirs is disclosed. During an operation of a twin-roll casting machine with arcuate worn steps developing on side weirs due to rotational sliding contact of chilled rolls, the thickness of a steel strip from a nip is reduced, and the center-to-center distance between the rolls is increased with the side weirs in contact with ends of the rolls being displaced upward. This prevents interference of outer peripheries of the rolls with boundary surfaces adjacent to the arcuate worn steps of the side weirs. | 01-19-2012 |
| 20130240170 | ULTRA-THIN SLAB OR THICK-STRIP CASTING - A system of twin-roll casting an ultra-thin slab or thick-strip of metal with a liquid core still present inside the hollow shell of the casting as it exits the nip of the opposing counter rotating casting rolls. The wide sides of the cast shell are formed against a recessed casting surface on each roll and the narrow end walls of the shell are formed against the tapered ends of the recessed area so one half of the narrow end wall is formed on each roll and the two halves are joined together at the nip to form the full perimeter of the metal casting. A liquid-cooled copper mold liner provides continued support to each of the four sides of the casting below the twin-rolls and contact with those chilled copper mold liners continues to remove heat from the liquid core of the casting enabling the shell to continue growing in thickness. As the casting exits the mold it will be of adequate thickness to pass through opposing pairs of support rolls below the mold without bulging where water sprays can provide the additional cooling needed for final and complete solidification. A variation of this system uses one or more separating dams to cast different metals or different alloys of the same metal to integrally cast a dual-layer or multi-layer ultra-thin slab or thick strip of metal with a thin metal layer on one or both of the wide and narrow end casting surfaces. | 09-19-2013 |
