摘要： Thin steel strip (11) is passed through a pinch roll stand (12) comprising pinch rolls (13) to a hot rolling mill (16) comprising work rolls (17) and backing rolls (18). In advance of rolling mill (16) the strip passes over support rolls (15). An anti-crimping guide roll (21) located immediately in advance of the rolling mill (16) is mounted on a pair of rocker structures (22) so as to be raisable from a lower inoperative position to lift the strip out of a straight line path so as to pass around the anti-crimping roll and to be wrapped about the upper work roll (17) in advance of the nip (26) through an angle of wrap of at least 10 DEG . Due to the wrapping of the strip around the upper work roll, (17), that roll supports the strip and resists buckling of the strip and the generation of crimping defects.

摘要： Continuous strip casting device comprises a pair of parallel casting rolls (3a, 3b) onto which molten metal is supplied by metal supply means (1). Casting rolls (3a, 3b) are enclosed by a casting chamber (4) into which hot strip (10) is delivered downwardly from the casting rolls. Strip (10) passes downwardly into a cooling chamber (15) where it can either fall into a moveable scrap box (17) at the bottom of chamber (15) or be guided by operation of moveable apron (14) through an exit door (20) from chamber (15) into a heat exchange chamber (19) provided with heaters (53). A pair of seal rolls (6a, 6b) are moveable in a seal chamber (5) to form a seal between chambers (4) and (15). Chambers (4), (15) and (19) are provided with respective gas inlets (24), (29) and (57) to admit oxidation inhibiting gas into those chambers. Scrap box (17) is moveable into an out of the bottom of chamber (15) via a scrap box exchange chamber (17) fitted with an airtight door (42).

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： Casting rolls (12) for a twin roll continuos casting machine comprise a plurality of cooling passages extending through a central portion (17). The cooling passages comprise longitudinal cooling passages (14). The cooling passages also comprise at least one bend in the cooling passages which requires cooling fluid flowing through a cooling passage to undergo a change in direction. Each casting roll also comprises a flow control member, such as baffles (32), positioned in the bend to control the flow of cooling fluid around the bend.

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： Thin steel strip (11) is passed through a pinch roll stand (12) comprising pinch rolls (13) to a rolling mill (16) comprising a pair of work rolls (17) and upper and lower backing rolls (18). Strip (11) passes through the bite between work rolls (17) and strip squeezing forces are applied between the work rolls to reduce the thickness of the strip. Pinch rolls (13) apply tension to the strip passing to the work rolls (17). In order to minimize generation of crimping defects in the strip, the tension applied by the nip rolls (13) is high enough to ensure no part of the strip entering the work rolls is in longitudinal compression such as to exceed the buckling stress of the strip. The applied tension is sufficiently low as to produce no more than 1% strip elongation through creep. The strip may be hot rolled by work rolls (17) at a temperature in the range 700°C-1200°C.

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.
