Abstract (en)

[origin: WO2012107881A1] A hot-rolling machine (1) for wire rods and the like which comprises a number of rolling units (2) that are arranged in cascaded to one after another along the wire-rod feeding path (p) so that each rolling unit (2) can plastically deform the high-temperature wire rod (b) that moves along said path (p); each rolling unit (2) being provided with: a rolling stand (3) that is arranged on the wire-rod feeding path (p) and is provided with two counter-rotating and opposed milling rollers (4) that are arranged one beside the other, locally substantially parallel and substantially tangent to one another so as to form/delimit a rolling groove or throttling (4a), through which the wire rod (b) to be hot-rolled is forced to pass; and a mechanical gear reduction unit (5), which is arranged beside the rolling stand (3) and is structured so as to be able to drive simultaneously in rotation the two rolls (4) about the respective longitudinal axes (L); the mechanical gear reduction unit (5) of each rolling unit (2) being structured so as to form, with the corresponding rolling stand (3), a single sectional elementary module (2) that is structured for being aligned with other similar sectional elementary modules (2), along the wire-rod feeding path (p) and for being mechanically coupled to the immediately adjacent sectional elementary modules (2), in so as to compose/form a catenary of rolling units (2 which are reciprocally connected so as to transmit torque in cascade from one another.
