    摘要： Strip material (12) is fed to a reduction rolling mill (16) by a steering device (14) in the form of a pinch roll stand comprising pinch rolls (50) to which strip gripping forces are applied by hydraulic cylinder units (52) located at the ends of the pinch rolls. Reduction mill (16) is similarly provided with a pair of hydraulic cylinder units (62) which are independently operable to vary the pressure applied by the reduction rolls (16A) across the strip. Sensors (51) and (61) sense the position of the strip at a first location in advance of the pinch rolls (50) and a second location in advance of the rolling mill. This output of sensors (51) and (62) is fed to a controller (63) which controls operation of both sets of hydraulic cylinder units (52) and (62) to steer the strip.

    摘要： Method of producing strip comprising continuously casting plain carbon steel into a strip of no more than 5 mm thickness and coiling the strip. The strip is subsequently uncoiled and cold rolled then annealed to produce a stress relieved microstructure therein. The cold rolling produces a cold reduction sufficient to increase the tensile strength off the strip to at least 680 MPa but is such that the total elongation to break off the strip after the annealing is in the range 8 % to 12 %. The cold rolling may produce a cold reduction of the strip thickness in the range 40 % to 80 %. The continuously cast strip may be optionally in-line hot rolled prior to coiling to produce an initial strip thickness reduction in the range 40 % to 60 %.

    摘要： A twin roll casting machine and method of continuously casting thin strip that enables the manufacture of thin strip by applying a thrust force through casting roll support structures on each casting roll to bias the casting rolls together, such that a majority portion of the thrust force counterbalance ferrostatic pressure. Cooling water is caused to flow through rotary joints (10) that are attached to one or both of the ends of casting rolls 1. The rotary joints 10 at each casting cause cooling water to flow into and from the passages in the casting rolls and exert forces on the casting rolls generally in the direction along the rotational axis of the casting rolls 1.

    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).
