Benefits of technology
The invention provides smaller rolling units for hot-rolling lines, which allows for more space in the line. This makes it easier to install and maintain the equipment.
Problems solved by technology
Albeit guaranteeing a considerable increase in the productivity per hour of the plant, the bifurcation of the hot-rolling line causes a significant increase in the amount of machinery involved in the production of the concrete-reinforcing bars, with the increase in running costs that this involves.

Embodiment Construction
[0017]With reference to FIGS. 1 and 2, reference number 1 designates as a whole a hot-rolling machine for wire rods and the like, which finds particularly advantageous use in the production of concrete-reinforcing bars.
[0018]The machine 1 is basically made up of a series of rolling units 2 that are arranged in cascaded one after the other along the wire-rod feeding path p so that each rolling unit 2 can deform plastically the high-temperature metal, wire rod b that moves along the path p, causing a slight reduction of the nominal section thereof.
[0019]Preferably, though not necessarily, the wire-rod feeding path p is substantially rectilinear and extends horizontally.
[0020]Each rolling unit 2 is equipped with a rolling stand 3 that is arranged exactly on the wire-rod feeding path p, and is provided with two opposed and counter-rotating milling rollers 4 which have a substantially cylindrical shape and are arranged one beside the other, locally substantially parallel and substantiall...

Abstract
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.
Description
TECHNICAL FIELD[0001]The present invention relates to a hot-rolling machine for wire rods and the like.[0002]In greater detail, the present invention relates to a machine for the production of hot-rolled concrete-reinforcing bars, use to which the following description refers purely by way of example without this implying any loss of generality.BACKGROUND ART[0003]As is known, concrete-reinforcing bars are obtained by subjecting a steel wire rod with a roughly circular section to a process of hot-rolling that brings about a progressive reduction in the nominal section of the wire rod.[0004]Hot-rolling lines that are used for performing this particular metallurgical operation are usually made up of an appropriate number of rolling units that are arranged in cascade one after another along the wire-rod feeding path, so that each rolling unit is able to bring about a slight reduction of the nominal section of the high-temperature steel, wire-rod whilst the latter advances along the hot...
