The invention relates to an apparatus (10) for the thermal treatment of metallic products, which comprises (a) a support and transport plane (24); (b) at least one collector module (12) comprising at least one collector (14, 16), the collector (14) being provided with a perforated plate (22) facing the support and transport plane (24); (b-2) a conduit (20) connected to said at least one collector (14), and (b-3) integrated in said conduit (20), at least one stop valve (18). The stop valve (18) is situated at a distance from the collector (14) which does not exceed 60 cm. The perforated plate (22) is provided with holes which are arranged in rows parallel to each other but not in parallel rows with respect to the sides of said perforated plate. The rows are inclined with respect to two opposite sides of the plate (22) of an acute angle.

Apparatus for rolling a metal product comprising a plurality of rolling units (11), each provided with a respective rolling roll (12). Each rolling unit (11) comprises a support assembly (17) selectively rotatable around an axis of rotation (Z), and comprising a support rod (20) provided with an attachment portion (23) of a roll (12), and an actuation assembly (35) configured to selectively move the support rod (20) along the axis of rotation (Z) to allow the removal of the roll (12).

The invention relates to an apparatus (10) for the thermal treatment of metallic products, which comprises (a) a support and transport plane (24) for locating and advancing a product to be treated; (b) at least one collector module (12) comprising (b-1) at least one collector (14, 16), the collector (14) being provided with (b-1.1) a perforated plate (22) on that side of the collector (14) which is facing the support and transport plane (24); (b-2) a conduit (20) connected to said at least one collector (14) for feeding it with a fluid, and (b-3) integrated in said conduit (20), at least one stop valve (18), in particular an on-off valve, to permit or preclude the flow of said fluid into said at least one collector (14). The stop valve (18) is situated at a distance from the collector (14) which does not exceed 60 cm, preferably does not exceed 35 cm, and still more preferably does not exceed 10 cm. The perforated plate (22) is provided with holes (36) which are arranged in rows (38) parallel to each other but not in parallel rows with respect to the sides (22a, 22b) of said perforated plate. The of an acute angle (13).
