摘要： PURPOSE:To enable industrial manufacture of an extremely thin strip by providing a brush roll specifying tension characteristics of a pinch roll. CONSTITUTION:Molten metal 3 flows from a powering nozzle 1 on a cooling roll 2 which rotates at a high speed, and is quenched to form a quenched thin metallic strip 4. After this is separated by an air knife 5, it is caught by a pinch roll composed of a solid roll 10 and a brush roll 9 and guided to a coiling device. Then, this device is provided with the brush roll to which the tension characteristic P/delta of the pinch roll is indicated by formula I. In the formula I, P: unit tension(kgf/mm ), delta : indentation (mm) of the brush roll. In this way, transfer and coiling of an extremely thin, quenched metallic sheet can be performed in proper tension and centering.

摘要： PURPOSE:To introduce and convey a metal strip without any breakage by detaching the metal strip rapidly solidified with a cooling single roll, arranging the conveying guide toward introducing direction to the pinch roll and passing the metal strip through the conveying guide under non-contacting condition. CONSTITUTION:The strip 2 detached with an air knife 3 from cooling roll 1 is apt to fly to the normal direction at the detaching position on the roll 1. Therefore, by arranging the conveying guide 4 toward this direction, the strip 2 is not brought into contact with the inner circumferential face of the conveying guide 4 to scarcely receive impact. In this result, the crack and breakage in the strip 2 are not developed.

摘要： PURPOSE:To enable stable carrying by passing a metal strip rapidly cooling and solidifying molten metal on the surface of cooling roll to pinch rolls composing of one pair of brushing roll and solid roll and specifying the speed of the pinch rolls at the time of carrying the metal strip to the coiling reel. CONSTITUTION:The rapid cooled and solidified metal strip on the cooling roll 1 surface is passed to the pinch rolls 7 composing of one pair of the brushing roll 7b and the solid roll 7a. Variety of tension developed caused by shifting of the pinch rolls 7 is absorbed with slip in the pinch rolls 7 and meandering of the strip is prevented with the centering function of the brushing roll having helical gear shape. The peripheral speed V1 of the cooling roll 1, the peripheral speed V2 of the pinch roll 7 and the shifting speed V3 of the pinch roll 7 are made to widen the permissible range of the adjusting accuracy of the speed by satisfying V2+V3>V1 and V1>=V3. By this method, in the carrying process to the reel 12 winding the rapid cooled strip, by correcting the line and giving the suitable tension, the stable carrying is executed.

摘要： PURPOSE:To uniformize molten metal pouring and to reduce deviation from a foil thickness standard by arranging a weir between a tundish and a pouring nozzle and forming plural grooves in the weir. CONSTITUTION:The tundish 3 is arranged below a holding vessel 1 and the weir 4 is also arranged between the pouring nozzle 5 and the tundish 3. Further, the plural grooves are formed in the weir 4, so as to overflow into the pouring nozzle 5 as plural dispersed flows for the molten metal. Then, a depth of the molten metal in the nozzle 5 is adjusted to about 50-400mm to reduce the deviation from a foil thickness standard. As the plural grooves are formed in the weir 4, the molten metal flow at overflowing the weir is enlarged for its resistance and is reduced for effect of a surface tension, and thus, a supply of the molten metal for width direction is uniformized. Therefore, in this way, uniform pouring and reducing of the deviation from the foil thickness standard are obtd.
