FIELD: equipment for making powder wire in metallic envelope with folded seam having diameter 6 - 20 mm and used, mainly, for out-of-furnace treatment of steel and cast iron. ^ SUBSTANCE: line is provided with reduction unit having alternating vertical and horizontal duo-stands of cantilever type in which radial adjustment of rolling rolls is possible. Horizontal stands are driven ones, they have gear ratio providing increased rolling speed while taking into account elongation factor in previous stand. Line includes mechanisms for adjusting, tuning rolls. ^ EFFECT: lowered idle time periods at changing rolling mode for rolling wire with different diameter, lowered number of calibrated rollers in reducing unit of stands. ^ 7 dwg |
