Abstract: Assembly (12) to clamp a rolling ring (10) associated with a ring-bearing shaft (11) of a rolling mill stand, the clamping assembly (12) comprising a labyrinth ring (13), an alignment bush (18), a cap (15), a spacer (14), a closure flange (16) and a locking screw (17), means (30, 31) performing rotational clamping by frontal coupling being included between the cap (15) and the rolling ring (10), the spacer (14) having a frontal abutment (33) against the cap (15) and abutment means (40) against the rolling ring (10) and being associated axially with the cap (15) by means of key means (23), the key means (23) cooperating with seatings (25) provided in the spacer (14) in a longitudinally sliding manner, the spacer (14) defining a first gap (29a) of a required width between the opposed surfaces of the cap (15) and of the rolling ring (10) and a second gap (29b) between the means (30, 31) performing rotational clamping by frontal coupling.

Abstract: Cooling chamber which is of the type installed in a rolling line downstream of the last finishing stand and/or between the finishing stands and comprises a casing (11) containing a cavity (18) for circulation of a cooling fluid cooperating with a lateral opening (17) permitting immission of a cooling fluid and positioned on a plane perpendicular to the longitudinal axis of the casing (11), the casing (11) including a seating (12) for the axial sliding of a slider (14) able to move longitudinally through the fluid circulation cavity (18), the slider (14) containing an axial through bore (15) for the feeding of the rolled product, the fluid circulation cavity (18) being defined by a flange (13) containing an axial through bore (16) which is coaxial with the axial sliding seating (12) and is conformed with a taper cooperating with the slider (14), the flange (13) being complete in itself or extending with a tube (19) to contain the rolled product and cooling fluid, the slider (14) having its downstream portion p
