Patent ID: 8596335

Claim:
A method for the continuous casting of slabs, thin slabs, blooms, preliminary sections, rounds, tubular sections or billets ( 1 ) from molten metal in a continuous casting plant ( 2 ), where metal flows vertically downward from a mold ( 3 ), where a metal strip ( 1 ) is then guided vertically downward along a vertical strand guide ( 4 ), cooling as it moves, where the metal strip ( 1 ) is then deflected from the vertical direction (V) to the horizontal direction (H), and where in a terminal area of the deflection of the metal strip ( 1 ) into the horizontal direction (H) or after the deflection into the horizontal direction (H), a mechanical deformation ( 5 ) of the metal strip ( 1 ) is carried out, wherein, to minimize scaling, the metal strip ( 1 ) is cooled at a heat-transfer coefficient of 3,000 to 10,000 W/(m 2 K) in a first section ( 6 ) downstream of the mold ( 3 ) and upstream of the mechanical deformation ( 5 ) of the metal strip ( 1 ) with respect to a direction of conveyance (F) of the metal strip ( 1 ), where in a second section ( 7 ), downstream of the cooling with respect to the direction of conveyance (F) of the metal strip ( 1 ), a surface of the metal strip ( 1 ) is heated to a temperature above Ac3 or Ar3 by heat equalization in the metal strip ( 1 ) with or without reduced cooling of the surface of the metal strip ( 1 ), after which the mechanical deformation ( 5 ) is carried out in a third section ( 8 ), wherein the cooling in the entire casting process is limited to a region of the vertical strand guide ( 4 ), wherein a pressure of less than 20 bar is used for a cleaning descaling, wherein the cooling is carried out using first, movable cooling devices and second, stationary cooling devices, the first cooling devices having a higher cooling capacity than the second cooling devices, the cooling including first cooling the metal strip with at least one of the second cooling devices and then cooling the strip with the first cooling devices.
