Apparatus for producing rapidly cooled metal strip

Abstract

Abstract PURPOSE:To enable mass-production of rapidly cooled metal strip by making an air knife for detaching the rapidly cooled metal strip from cooling roll surface as orthogonally crossing a pass line and freely swingable with a horizontal swinging axis as center. CONSTITUTION:Molten metal is injected from an pouring nozzle 1 and molten paddle 3 is formed at between the nozzle and the cooling roll 2, and the molten metal is rapidly solidified with dissipation of the heat from the cooling roll to make the rapidly cooled metal strip 4. The metal strip stuck on the cooling roll is detached with air 6 injected from the air nozzle 5 and flown in the hood 8. The metal strip coming to pinch rolls composed of a brush roll 9 and a solid roll 10 is applied with tension with the pinch rolls to form the pass line at between the pinch rolls and a deflecting roll 7. The metal strip going out from the pinch rolls is made to pulverized strip 14 with a fan 11. By this method, the continuous coiling of the metal strip is stably executed and the mass production of metal strip can be executed.
