摘要： 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.

摘要： A metal strip casting apparatus and method of casting metal strip include assembling a pair of counter-rotatable casting rolls positioned laterally forming a nip between for casting, and assembling a pair of brush rolls, each of the brush rolls associated with one of each of the casting rolls. Each brush roll includes at least one spaced apart brush line extending substantially along the axial length of the casting roll. The brush lines may form a spiral, zigzag, wave or crisscross array about the brush roll. The brush roll may include one or more staggered rings with regularly or irregularly spaced apart bristles which form the brush lines. The brush lines may be between 10 to 50 mm apart and separated by between 2 mm to 45 mm of open space. The brush lines may be one line per 10 mm to 90 mm of axial length of brush roll.

摘要： A delivery nozzle for a twin roll caster for making has an elongated nozzle body having elongated extending side walls and end walls to form a nozzle trough, and side outlet openings in the side walls capable of discharging molten metal from the nozzle body laterally outwardly from the side walls of the nozzle body. The side walls below the side outlet openings extend downwardly to converge and meet at the lower extremity to form a bottom part of the nozzle body configured to inhibit entrapment of gas bubbles in a casting pool. The side walls forming the bottom part may have generally flat exterior surfaces throughout and meet at an acute angle to form a discrete edge along the nozzle body, or alternatively, convex curved external surfaces meeting at the bottom extremity in an arcuate shape along the nozzle body.

摘要： 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.

摘要： A nozzle end is provided with an extension 11 which has a lower portion immersed in a molten metal pool and extends toward a side weir 2 such that a stagnation area disappears on a free liquid surface of molten metal.The extension 11 is in the form of a quadrangular pyramid lying sidelong and is converged to a point P1 extremely close to the side weir 2. According to this molten metal feed nozzle, a stagnation area on a free liquid surface of molten metal is displaced by the extension 11 contiguous with the nozzle end to suppress generation of an unwanted solidification shell. Thus, no unwanted solidification shell is pinched as foreign matter by solidification shells generated on outer peripheries of chilled rolls 1 for production of a strip and break of a strip derived from enlargement of nip between the rolls can be averted.

摘要： A casting roll having an outer periphery capable of being efficiently cooled is disclosed. The casting roll has a roll body on which side weirs abut, short tube-shaped supports each coaxially with and protruding from the roll body, a stub axle fitted into the support, a sleeve fitted over the support and a flange contiguous with the stub axle and abutting on the sleeve on a side away from the roll body. The roll body is formed with longitudinal cooling passages passing through the roll from one end to the other end of the roll as well as radial cooling passages each adjacent to a corresponding end of the roll and extending from an inner periphery of the roll to a corresponding longitudinal cooling passage. A plug is fitted into each end of the longitudinal cooling passages and abuts on the sleeve. With a distance between the longitudinal cooling passages and the outer periphery of the roll body being reduced as much as possible, cooling water is passed through a portion of the roll body.
