Steel Finishing Rolling Mill Equipment

Equipment Application

The finishing mill group is the extra-heavy top cross 45° high-speed wire rod finishing mills designed for the high-speed wire rod production line.

The finishing mill group is located in the high-speed wire rod workshop. Rolling by 10 unit rack continuous micro-tension rolling mill, rolling the F17~F21 mm of rolled piece transported from upstream into F5.5~F16 mm finished wire rod. The mill guaranteed exit speed is 90 m/s. (When the specification of finished product is F5.5 mm)
