Direct Square Tube Mill Line

Direct Square Tube Mill Line is used to produce a square and rectangular tube directly, from square to square or rectangular to rectangular directly.

Characteristics and Advantages of Direct Square Tube Mill Line

• Compare with a round to square or rectangular roll forming method, directly roll forming to the square or rectangular method is better for the shape at the edge of cross-section, comparatively, semi-diameter of the inner arc is small, and the brim is flat, the outlook is regular.

• The tube mill line load is low, especially the sizing machine.

• The width of the steel strip is reduced by about 3% compared with around to square or rectangle, so this tube mill will save the consumption of raw material.

• Directly roll forming method adapts the multi-point bending way, avoids the axial force and side abrasion, reduces roll forming steps while ensuring the quality, meanwhile, this method reduces the power wastage and roller abrasion.

• Directly roll forming method adapts the combined type roller on the most of the stands, this realizes that one set rollers can produce dozens of square or rectangle tubes with different specification. This decreases the store of rollers, lowers the cost of about 80% on rollers.
