Abstract
A method and device for producing a strand of metal by means of a continuous-casting installation which has at least one cooling device for cooling the strand, the cooling device being assigned at least one reduction stand for reducing the thickness of the strand, the strand, during the thickness reduction, having a solidified skin and a liquid core. The cooling is set, by means of a temperature and solidification model, in such a manner that the solidification boundary between the solidified skin and the liquid core when the strand enters the reduction stand corresponds to a predetermined set solidification boundary between the solidified skin and the liquid core.
Claims8
A method for producing an extrusion casting system comprising a metal strand using at least one cooling device for cooling the strand, the cooling device being associated with at least one reduction stand for reducing the thickness of the strand, the strand, which during the thickness reduction has a solidified skin and a liquid core, wherein the at least one cooling device is arranged ahead of the at least one reduction stand and cooling is adjusted by means of a temperature and solidification model so that a solidification boundary between the solidified skin and the liquid core corresponds to a predetermined set solidification boundary between the solidified skin and the liquid core when the strand enters the reduction stand.
