Abstract

The installation comprises a single tank at the entrance for containing a lubricant, an assembly of wire-drawing roller blocks, each comprising two pairs of rollers (1, 2; 3, 4) arranged in the vicinity of one another along planes perpendicular to one another which contain the wire and which are respectively parallel to first and second predetermined reference directions (V, H), in order to produce, during successive cold-rolling passes, progressive cross- sectional reductions, a calibrating roller block located downstream of the wire-drawing roller blocks and comprising two pairs of rollers arranged in the vicinity of one another along planes perpendicular to one another which contain the wire and are respectively parallel to the said first and second reference directions (V, H), in order to carry out a very small additional pass effecting only a reduction of the diameter of the wire at most equal to approximately one tenth of a millimetre, a first series (160) of an odd number of straightening rollers (161-165) arranged in staggered formation in a first plane parallel to the said first reference plane (V), and a second series (170) of the same odd number of straightening rollers (171-175) arranged in staggered formation in a second plane parallel to the said second reference plane (H). The invention is used particularly for making smooth steel wires for welded concrete-reinforcing grids. <IMAGE>
