Abstract (en)
[origin: EP0471608A1] According to this method, the metal is solidified in a continuous-casting ingot mould consisting of two cooled rolls (2) rotating in opposite directions and arranged opposite each other so as to define a casting space between them, a solidified steel strip (3) is extracted continuously from the ingot mould, and, under the ingot mould, the said strip is subjected to a quenching medium (6) in order to cool it sufficiently rapidly in order to prevent the formation of austenite. This medium may consist of a quenching bath, placed in a container (4) arranged under the rolls (2), and whose bottom is pierced with an opening (5) for the passage of the solidified strip (3). It may also consist of an inert gas in the liquid state sprayed onto the product by nozzles. The steel strips obtained are easier to trim and to coil on exit from the casting line, by virtue of the absence of martensite in the ferritic matrix. <IMAGE>
