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 positioned within the fluid circulation cavity (18), this downstream portion being defined by a first downstream truncated-cone segment (20) having its vertex facing downstream and tapered with a taper '.alpha.', a first intermediate cylindrical segment (21) with its axis substantially parallel to the longitudinal axis of the slider (14), a second intermediate tapered segment (22) having a taper '.gamma.' and a second upstream cylindrical segment (23), an outer sidewall (31) defining the axial sliding seating (12) off the slider (14) and extending into the fluid circulation cavity (18) at least to the vicinity of the axis of the lateral opening (17) and being conformed with a taper '.alpha. 2' connected (30) to the upstream sidewall of the fluid circulation cavity (18), the bore (16) of the flange (13) including a taper '.beta.' which is a function of the taper '.alpha.' of the slider (14).
