Structural Characteristics and Function of the Equipment
The finishing mill group is designed for high speed wire rod production line of heavy top 45 ° high speed wire rod finishing mill group, and is located in high-speed wire-rod workshop. Finishing mill unite is combined with 10 mills, three Φ200 mills and seven Φ150 mills, speed increasing box, support base, arc coupling, waterproof slot, waterproof plate, buffer tank, the protective cover, coupling,piping and guide of finishing mill. Through 10 unit rack the continuous micro-tension rolling mill will be transported upstream Φ17 ~ Φ21 mm of rolling piece, rolling become Φ5.5 ~ Φ16 mm finished wire. The working speed of 75 m/s is insured. (The specification of end products is Φ5.5 mm.)
