Directly Forming to Square

The square or rectangular shaping is formed out before the tube welding.
We can also customize according to customer’s requirements.
Process Flow
Steel Coil → Uncoiling → Flattening/Leveling → Shear & End Cutting → Coil Accumulator → Forming → Welding → Deburring → Water Coiling → Sizing → Straightening → Cutting → Run-out table
Advantages
1.Compare with round into square& rectangle forming way, this way is the better for the shape of cross-section, comparatively, semi diameter of inner rac is small, and the brim is flat, the side is regular, the perfect shape of the tube.
2.And the whole line load is low, especially the sizing section.
3.The width of the steel strip is about 2.4~3% smaller than that of the round into square/rectangular, it can save the cost of raw material.
4.It adopts the multi-point bending way, avoids the axial force and side abrasion, reduces 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 tubes with different specifications, it decrease the store of roller, reduce the cost about 80% on 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, reduces the labor intensity, improve the production efficiency.
