    Abstract: The invention relates to a method for the continuous casting of slab, thin slab, bloom, preliminary section, round section, tubular section or billet strands (1) and the like from liquid metal in a continuous casting plant (2) in which metal discharges perpendicularly downwards from a mould (3), wherein the metal strip (1) is then guided vertically downwards along a perpendicular strand guide (4) and is cooled in the process, wherein the metal strip (1) is then defelcted from the vertical direction (V) into the horiziontal direction (H) and wherein mechanical forming (5) of the metal strip (1) is effected in the final region of the deflection into the horizonal direction (H) or after the deflection into the horizontal direction (H). In order to obtain a surface which has as little scale as possible, provision is made according to the invention for the metal strip (1) to be cooled with a heat transfer coefficient of between 2500 and 20 000 W/(m2 K) in a first section (6, 6A, 6B) in the conveying direction (F) of the metal strip (1) downstream of the mould (3) and upstream of the mechanical forming (5), wherein the surface of the metal strip (1) is heated to a temperature above Ac3 or Ar3 in the conveying direction (F) downstream of the cooling in a second section (7) by heat compensation in the metal strip (1) without or with reduced cooling of the surface of the metal strip (1), after which, in a third section (8), the mechanical forming (5) is effected. The invention also relates to a continuous casting plant, in particular for carrying out this method.
