Direct Forming Square 150x150mm
Model: LW600 (150x150mm) 
Directly Forming to Square and Rectangular Tube Mill 
the square or rectangular shaping is formed out before the tube welding, with important advantages in terms of power and material cost reduction.
Features: 
1) Compare with round into square & rectangle forming way, this way is better for the shape at the edge of cross section, comparatively, semidiameter of inner rac is small, and the brim is flat, the side is regular, perfect shape of tube 
2) and the whole line load is low, especially the sizing parts. 
3) the width of steel strip is small about 2.4-3% than round into square & rectangular, it can save the consume 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 it 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 sizes of Square & Rectangular Pipe with different specification, it decrease the store of roller, low the cost about 80% on roller, Fast the bankroll turnover, short the time one new product design. 
6) All the Rollers are common shares, no need to replace the Rollers when change pipe size, just adjusting the Position of Rollers by Motor or PLC, and realized the full automatic control; It greatly reduces the Roll changing time, reduces the labor force, improves the production efficiency.
