TOPE Reducing rolling mills are specially designed to reduce round, metal sheathed tubular elements. They contain a number of pairs of driven rolls, mounted in a V-shaped bearing box assembly.
Sintered carbide rolls(Cr12,W18Cr4V) are recommended for annual production more than one million meters of hard material. The life can be 5~10 times than tool steel.
12 stations can process thicker tubes and higher reduction rates than 8 stations.
The min. length of tube:110mm
Tube diameter after compressing: Φ5.2mm～Φ19.0mm
The max. diameter before compressing: 21mm
After compressing, the straightness can reach 1:300, and the roundness can reach 0.07mm.
The minimum safety distance between tubes should be 500mm, or one third of the element length.
