Hot rolled wire straight length prodn. - is passed through straightening roller set rotating around wire before descaling

摘要

The mechanism is intended for producing straight lengths (54) of descaled rod from hot-rolled wire material (50) wound off a reel (1). A cold-rolling set (3) reduces the wire dia. with a wire tensioning unit (5,7) behind the set (3), a descaling unit (6) and a cutting unit (49). A rotating set (17) of straightening rollers (20,21) is arranged between the cold-rolling set and the descaling unit and may comprise three rollers (20,21) arranged around the wire axis at an angle. The rollers may be concave or cylindrical. There may be two such sets of straightening rollers.
