Into the spaces (19a,19b) between the cast strip (6) emerging from between the rolls (1,2) where they come closest to each other (3) and the rolls themselves (1,2) a flow of coolant is injected or blown by means of nozzles allocated on both sides of the strip (6). In case of an asymmetric emergence of the strip (6) due to increased adhesion to one of the rolls (1,2), the resulting asymmetric conditions with respect to cooling effect and pressure of the coolant on both sides of the strip cause the strip to continually be redirected into a symmetric position. This stabilizing effect renders it possible to achieve a much greater length of contact between the cast metal (5) and the rolls (1,2) and consequently to realize an essential increase of the production rate of the casting line.
