Direct Forming to Square Tube Mill

The square or rectangular shaping is formed out before the tube welding, with important advances in terms

of power and material cost reduction.


1) Compare with round into square & rectangle forming way, this way is better for the shape at the edge of cross section, comparatively, semi diameter of inner rac is small, and the brim is flat, the side is regular, perfect shape of tube.

2) The whole line load is low, especially the sizing section.

3) The width of steel strip is about 2.4-3% smaller than that of round into square/rectangular, it can save the cost of raw material.

4) It adopts the multi-point bending way, avoid the axial force and side abrasion, reduce the forming step while ensure the quality, meanwhile ti reduce the power wastage and roller abrasion.

5) It adopts the combined type roller on the most of the stands, it realizes that one set of roller can produce

all the size of square/rectangular tubes with different specifications, it decrease the store of roller, reduce the cost about 80% on the roller, fast the bankroll turnover, short the time on new product design.

6) All the roller are common shares, no need to replace the rollers when change tube size, only adjusting the position of rollers by motor or PLC, and realized the full automatic control; It greatly reduces the

roller changing time, reduce the labor intensity, improves the production efficiency.
