The present invention relates to an apparatus for tempering hot articles, in particular an apparatus for homogeneous, contactless tempering of primarily non-endless surfaces that are to be tempered; the tempering apparatus has at least one tempering blade or a tempering cylinder; the tempering blade or tempering cylinder is embodied as hollow and has a tempering blade nozzle edge or a plurality of tempering cylinders arranged in a row; in the nozzle edge at least one nozzle is provided, which is aimed at an article to be tempered; and at least seven tempering blades are arranged in such a way that the flow pattern on the surface to be tempered forms a honeycomb-like structure; and to a method therefor.

Method for the homogeneous non-contact temperature control of non-endless surfaces which are to be temperature-controlled, and device therefor

In a method for the continuous casting of a thin metal strip according to the two-roll method, metal melt is cast into a casting gap formed by two casting rolls of the thickness of the metal strip to be cast, under formation of a melting bath. In order to form a particular texture within the cast metal strip and/or to influence the geometry of the metal strip, continuous casting is carried out by an on-line calculation based upon an arithmetic model describing the formation of the particular texture of the metal and/or the formation of the geometry of the metal strip, wherein variables of the continuous casting method affecting the formation of the texture and/or the geometry are adjusted in an on-line dynamic fashion, i.e. while casting takes place.
