90M Finishing Mill Group

The finishing block mill Hangji is designed for high speed wire rod production
line of heavy top cross 45 ° high speed wire rod finishing mill group. and is
located in high-speed wire-rod workshop.
Structural characteristics and function of the equipment:

The finishing mill group is designed for high speed wire rod production line of
heavy top cross 45 °high-speed wire rod line. and is located in high-speed
wire-rod workshop. Finishing mill unit is combined with 10 mills, three
Ø200mills and seven Ø150 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 upstreamØ17~Ø21mm of
rolling piece , rolling become Ø5.5 ~ Ø16mm finished wire. The working speed of
75m/s is insured.( The specification of end product is Ø5.5mm. )
