摘要： PURPOSE:To uniformize thin hoop width by settling a rolling reduction force standards at a driving side and an operating side for free cooling rolls and correcting the reduction forces based on difference with the actual reduction forces and detecting values of the roll gap. CONSTITUTION:Corresponding to driving and operating chocks 8A, 8B for the free cooling rolls 2, oil pressure sensors 22A, 22B are arranged respectively and also sensors 14A, 14B, which detect the roll gaps l1, l2 for the driving side and operating side, are arranged. A standard rolling reduction force settler 17 settles the standard reduction force P0 and outputs the standard reduction forces P01, P02 for the driving side and the operating side respectively. Based on the deviations between actual reduction forces P1S, P2S measured by the sensors 22A, 22B, and the standard reduction forces and the detected values of roll gaps l1, l2, an arithmetic device 20A, 20B calculate reduction forces to correct, to execute rolling reduction control. As a solidification at width direction is uniformized, width of the thin hoop metal is uniformized.

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.

摘要： PURPOSE:To improve a cooling effect and to obtain a thin metallic strip having excellent surface characteristics by cooling the thin strip coming out from the kiss part of a pair of cooling rolls while keeping the same in tight contact with the surface of one roll in the prescribed range in its circumferential direction in succession. CONSTITUTION:Molten metal 5 is charged into the kiss part 3 between cooling rolls 1 and 2 which rotate in mutually opposite directions, thereby forming a well 6. While the molten metal passing the part 3 receives rolling down forces, said metal cools quickly and solidifies and is conducted out as a thin strip 7. A gas for cooling is injected to one side of the strip 7 from a gas injecting header 8 disposed in proximity to the rear stream side of the part 3 to deviate the strip toward one roll 2 and to accelerate the cooling. Pinch rolls 9, 10 are provided on the down stream of the header 8 to draw out the solidified strip 7 by exerting prescribed pressure thereupon, and to keep the strip 7 in tight contact with the surface of the roll 2 in a prescribed angle range in its circumferential direction. The delivered strip 7 is coiled on a coiling reel 13 on the down stream.
