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 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 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.
摘要翻译：喷嘴端部设置有延伸部11，该延伸部11具有浸没在熔融金属池中的下部，并朝向侧面堰2延伸，使得停滞区域在熔融金属的游离液体表面上消失。延伸部11呈四边形金字塔的形式，并且会聚到靠近侧堰2的点P1上。根据该熔融金属进料喷嘴，熔融金属的自由液面上的停滞区域被与喷嘴端相邻的延伸部11，以抑制不想要的固化壳的产生。因此，可以避免不想要的凝固壳被异物引起，因为在冷却辊1的外周产生的固化壳产生条带，并且由辊之间的辊隙的扩大引起的条带断裂。

摘要： Start up method for initiating casting of metal strip in a twin roll caster comprising parallel casting rolls. A casting pool of molten metal is supported on the casting rolls and confined at the ends of the rolls by side closure plates and the rolls are rotated to deliver cast trip downwardly from the nip between them. One roll is continuously biased laterally toward the other roll either by spring biasing units or by hydraulic biasing units. On start up the gap between rolls 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 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 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.
摘要翻译：用于在包括平行铸辊的双辊铸造机中开始铸造金属带的启动方法。熔融金属铸造池被支撑在铸辊上，并通过侧闭合板限制在辊的端部，并且辊旋转以从它们之间的辊隙向下输送铸造脱模。通过弹簧偏置单元或通过液压偏置单元，一个辊被横向偏向另一个辊。在启动时，辊之间的间隙被设定为小于要铸造的带材的厚度，并且辊以这样的速度旋转，即在浇铸熔融金属以引发铸造带材时产生的厚度大于辊之间的初始间隙由此导致偏压辊从另一个辊身体移动以增加辊之间的间隙以适应铸钢带的厚度。这允许开始铸造，而不需要在辊之间引入虚拟棒。辊的圆周表面可以具有负冠部c，并且在辊的中心处的初始间隙可以是d0 = 2c + g0，其中g0是初始辊边缘间隙。

摘要： A method of controlling the formation of crocodile skin surface roughness on thin cast strip of plain carbon steel forming a casting pool of molten metal of plain carbon steel of less than 0.065% carbon supported on a casting surfaces above a nip, assembling a rotating brush to contact the casting surfaces in advance of contact with the molten metal, and controlling the energy exerted by rotating brushes against the casting surfaces of the casting rolls to clean and expose a majority of the projections of the casting surfaces of the casting rolls by provide wetting contact with the molten metal of the casting pool. The cleaning step may be done by controlling the energy of the rotating brush against the casting rolls based on the difference between the measured heat flux and the initially measured heat flux when the casting surfaces are clean, and automating the method.
