A hot-rolling machine for wire rods includes a number of rolling units arranged one after another along a wire-rod feeding path to plastically deform a high-temperature wire rod moving along the path. Each rolling unit includes a rolling stand arranged on the wire-rod feeding path and two counter-rotating milling rollers are arranged one beside the other, parallel and tangent to one another to form a rolling groove through which the wire rod is forced to pass. A mechanical gear reduction unit is arranged beside the rolling stand to drive simultaneously the two rolls about the respective longitudinal axes. The mechanical gear reduction unit forms, with one rolling stand, a single sectional elementary module structured for being aligned with similar sectional elementary modules, along the wire-rod feeding path and for being mechanically coupled to an immediately adjacent sectional elementary module to form a catenary of rolling units reciprocally connected to transmit torque in cascade from one another. |
