ABSTRACT:
The surface of each roll (2, 3) has a knurling constituted by two series of parallel grooves (5, 6) which are inclined to the axis (XX) of the roll and joining up at the center of the latter so as to form a series of chevrons, the two grooves (5, 6) of each chevron downwardly converging when they are on the side of the roll (2, 3) in contact with the liquid metal. The device is completed by a cage for extracting the cast product at a speed slightly higher than the speed of rotation of the casting rolls (2, 3). This arrangement avoids the formation of longitudinal or transverse cracks on the surface of the cast thin metal strip.
