    Abstract: Apparatus and method for continuously casting metal strip includes a pair of casting rolls having casting surfaces with a center portion, edge portions each having average surface roughness between 3 and 7 Ra, and intermediate portion between each edge portion and the center portion, the center portion average surface roughness between 1.2 and 4.0 times the edge portion surface roughness, and the intermediate portions average surface roughness between that of the edge and center portions. The surface roughness of the center portion is tapered across its width, and may be tapered across its width is in stepped zones. The center portion may have surface roughness varied across the surface to correspond to a desired variation in metal shell thickness across the cast strip. The center portion may be at least 60% of the casting roll width, and each edge portion may be up to 7% of the casting roll width.

    Abstract: A strip caster (10) for producing a continuous strip (24) has a tundish (12) for containing a melt (14) and a pair of horizontally disposed water cooled casting rolls (22). The casting rolls are juxtaposed relative to one another for forming a pouring basin (18) for receiving the melt through a teeming tube (16) thereby establishing a meniscus (20) between the rolls for forming a strip (24). The melt is protected from the outside air by a non-oxidizing gas passed through a supply line (28) to a sealing chamber (26). Devices (29) for conditioning the outer peripheral chill surfaces of the casting rolls includes grit blasting nozzles (30A, 30B, 30C, 30D), a collection trough (32) for gathering the grit, a line (34) for recycling the grit to a bag house (36), a feeder (38) and a pressurized distributor (40) for delivering the grit to the nozzles. The conditioning nozzles remove dirt, metal oxides and surface imperfections providing a clean surface readily wetted by the melt.

    Abstract: An apparatus for producing a metal ribbon has a rotary roll. Molten metal is poured from a heated nozzle onto the outer peripheral surface of the roll to form a solidified metal ribbon on the roll surface. To facilitate easy separation of the metal ribbon from the roll surface, a jet of a non-oxidizing gas is directed to the point of separation of the ribbon from the roll surface. The roll surface just upstream of the metal-pouring nozzle is enclosed by a cover the inside of which is evacuated to assure intimate contact of the poured metal with the roll surface and thus improve cooling of the poured metal. A heater is provided in the cover to heat the roll surface just upstream of the metal-pouring nozzle for thereby removing dew droplets and ambient gases from the roll surface whereby the formation of depressions or recesses in the roll-containing ribbon surface is prevented.

    Abstract translation: 金属带的制造装置具有旋转辊。 将熔融金属从加热的喷嘴浇注到辊的外周表面上，以在辊表面上形成固化的金属带。 为了便于金属带从辊表面的容易分离，非氧化气体的射流被引导到带子与辊表面的分离点。 金属浇注喷嘴刚好上游的辊表面由盖子包围，盖子内部被抽真空以确保浇注的金属与辊表面的紧密接触，从而改善浇注金属的冷却。 在盖中设置有加热器，以便在金属浇注嘴的正上方加热辊表面，从而从辊表面去除露滴和环境气体，从而防止在含辊的带表面中形成凹陷或凹陷。

    Abstract: A twin-roll strip caster includes: a pair of casting rolls rotating in opposite directions to each other, and having an edge dam adhering to both end surfaces of the casting rolls in a length direction of the casting rolls; a submerged nozzle discharging molten steel between the pair of casting rolls; a meniscus shield disposed above the molten steel supplied through the submerged nozzle to prevent the molten steel from contacting air; and a focused gas supply nozzle disposed between the submerged nozzle and the meniscus shield to supply inert gas therebetween so as to displace air between the submerged nozzle and the meniscus shield before the molten steel is supplied.
