    摘要： Thin cast strip (12) is produced in a twin roll caster by delivering molten steel between the rolls (22) to form a casting pool. The casting pool is confined between the rolls by a pair of side dams (35) adjacent the ends of the casting rolls (27). Molten steel is delivered downwardly to the nip through a metal delivery system (24) having a tundish (26) and core nozzles (27). The tundish (24), core nozzles (27) and side dams (35) are replaced by first preheating the refractory components to be replaced at a removed location, and transferred from the preheating position to the operating position by transfer device(s) (49, 51, 52, 53, 55, 56). The worn refractory component is removed and the preheated replacement refractory component replaced in the operating position rapidly to avoid thermal shock to the refractories that are not replaced. The replacement can be accomplished in less than 5 minutes or less than 2 minutes.

    摘要： Twin roll caster for casting thin steel strip comprises chilled casting rolls (16) mounted on roll supports (104). One of the rolls is fixed and the other is moveable laterally and biased toward the other roll by biasing units (119) acting on the moveable roll supports (104). A casting pool of molten steel is supported on the rolls (16) and the rolls are rotated to produce a solidified steel strip delivered downwardly from the nip between the rolls. A substantially constant gap is maintained between rolls 16 such that unsolidifed molten metal passes through the nip between the solidified shells of the forming strip and solidifies below the nip. The biasing units (119) are effective to apply substantially constant and low biasing forces to the biased roll. The biasing forces may be between the same and slightly more than the force required to balance the hydrostatic pressure of the casting pool and to overcome the mechanical friction involved in moving the biased roll. Controlling these casting roll separation forces enables gauge variation in the strip to be reduced.

    摘要： Start up method for initiating casting of metal strip in a twin roll caster comprising parallel casting rolls (16). A casting pool of molten metal is supported on the casting rolls and confined at the ends of the rolls by side closure plates (56) and the rolls are rotated to deliver cast strip downwardly from the nip between them. One roll (16) is continuously biased laterally toward the other roll (16) either by spring biasing units (110) or by hydraulic biasing units (11). On start up the gap between rolls (16) is set so as to be less than the thickness of the strip to be cast and the rolls are rotated at such speed that on pouring of molten metal to initiate casting strip is produced to a thickness which is greater than the initial gap between the rolls thereby to cause the biased roll (16) to move bodily away from the other roll to increase the gap between the rolls to accommodate the thickness of the cast strip. This allows initiation of casting without the need for introduction of a dummy bar between the rolls. The peripheral surfaces of rolls (16) may have a negative crown c and the initial gap at the centres of the rolls may be d0=2c + g0 where g0 is an initial roll edge gap.

    摘要： Twin roll caster for casting metal strip comprises pair of parallel casting rolls forming nip to receive molten metal from elongate metal delivery nozzle formed in two pieces supported in end to end relationship with a gap between them. A pair of casting pool confinement plates are thrust against the ends of rolls by thrusters mounted with the side plastes on carriages forming part of moveable structures which are connected to the outer rends of nozzle pieces by pins and which can be moved by operation of screw jacks. The outer ends of nozzle segments can be accurately set in position relative to side plates prior to a casting and during a casting operation screw jacks can be operated so as to move the nozzle segments inwardly to match inward advance of the side plates as they wear.

    摘要： Roll caster (11) produces thin steel strip (12) formed on casting surfaces (22A) of casting roll (22) that passes through first enclosure (37) adjacent casting roll surfaces (22A) and, optionally, thereafter second enclosure (61). Enclosure (37) and/or enclosure (61) may be fitted with spray nozzles (71,72) and/or (67, 68) operable to spray fine water mist adjacent strip (12) to produce hydrogen gas in enclosure (37) while tending to avoid liquid water contact with steel strip (12) and casting surfaces (22A). If hydrogen gas is produced only in enclosure (61), the two enclosures (37, 61) are interconnected so that gas can flow from enclosure (61) to enclosure (37). Enclosure (37) and, if present, enclosure (61) are sealed to maintain positive pressure and oxygen levels less than the surrounding atmosphere, and with the presence of hydrogen gas, reduce formation of scale on the strip in enclosure (37) and, if present, enclosure (61).

    摘要： Apparatus for continuously casting metal strip comprises a pair of parallel casting rolls (16). In use of the apparatus molten metal is delivered between the casting rolls which are rotated to deliver cast strip product downwardly from the rolls. Casting rolls (16) are mounted on a roll module (13) installed in and removable from the caster as a unit. Module (13) is movable horizontally from a stand-by position to an intermediate position beneath a casting position of the rolls and can be hoisted from the intermediate position by operation of hoists (71) to lift the rolls (16) into their casting position.
