Abstract (en)

A method and a corresponding apparatus for dynamic straightening and surface cleaning : of steel wire rods and/or bars. The rolled-element (1) is subjected to a dynamic action, caused by the spindle-like orbital rotation (1.1) in the region between the two eccentric rotating bushes (3, 4). Upstream (2) and downstream (3) there are optional roller traction assemblies to produce the advancement of the rolled element. These assemblies are actuated, controlled and adjusted with respect to each other by virtue of a suitable transmission of motion with a differential device. Likewise, the two eccentric rotating bushes (3, 4) are moved by the motor (8) and by the corresponding drive with differential device (9). The iron scale and other impurities (7), which separate from the outer surface of the rolled element (1.1), due to the bending deformation (centrifugal effect) and to an aerodynamic effect, are collected in the container (6). The rolled element, when it exits from the region of spindle-like orbital rotation, exits in a straightened condition and with a clean outer surface.
