1. A roll line for a continuous casting machine comprising at least two roll modules (1), wherein each roll module comprises,-a shaft (2) extending in an axial direction and having a first axial end (21) of the shaft and a second axial end (22) of the shaft,-a roll mantle (3) having a cylindrical outer circumferential surface (31) extending in an axial direction and a cylindrical inner circumferential surface (32) extending in the same axial direction, wherein the roll mantle further has a first axial end (33) of the roll mantle and a second axial end (34) of the roll mantle,-first and second bearings (41, 42) mounted between the shaft (2) and the inner circumferential surface (32) of the roll mantle (3) such that the first and second bearings (41, 42) allow relative rotation between the shaft (2) and the roll mantle (3),-wherein a first axial end (21) of the shaft (2) and a second axial end (22) of the shaft (2) extend axially outside a first axial end (33) of the roll mantle and a second axial end (34) of the roll mantle, respectively, such that the shaft (2) has a first and a second axially extending shaft protrusions (23, 24),-wherein the roll module (1) further comprises first and second locking means (51, 52) for axially locking the first and second bearings (41, 42) and the roll mantle (3) to the shaft (2), the first and second locking means (51, 52) being located at least partly on the first and second respective shaft protrusions (23, 24), wherein a plane in which the first locking means intersect is perpendicular to the axial direction of the shaft and axially at a first axial end of the roll mantle, and wherein a plane in which the second locking means intersect is perpendicular to the axial direction of the shaft and axially at a second axial end of the roll mantle,-wherein the roller modules are arranged in sequence along an axis, and wherein the at least two roller modules are supported in two end support blocks and at least one intermediate support block,-wherein the at least one intermediate support block has an axial through hole for receiving two opposing shaft protrusions of two of the at least two roller modules,the roll module (1) comprises a spacer sleeve (8) between the roll mantle (3) and the shaft (2);

  • the roll module comprises two bearing knock-out rings (81,

         82);

    the bearing removing rings (81,

         82) are designed to be able to push against the outer and inner rings of the respective first and second bearings (41,

         42), respectively;

    the bearing release ring is designed to be pushed via an axial side (83) on the spacer sleeve (8) by pushing the spacer sleeve (8);

    two rotating fixtures (511,

         512) are provided on the first and second locking devices (51,

         52), respectively, the rotating fixtures (511,

         512) being insertable into holes of the locking devices of the other roll modules in the mill pass line, thereby rotationally locking the shafts of the roll modules relative to each other; and

    the rotational fixing means on the first locking means (51) and the rotational fixing means on the second locking means (52) comprise holes into which corresponding plugs from the other locking means of the other roller module can be inserted.
