Roller changing time is cut down greatly, breakdown section does not need to change moulds and just adjust is ok. And it can cut-down producing period.

1）Used In Producing Round Pipe

Do not need to change moulds in breakdown section, saving about 60% cost on the rollers
Roller changing time is cut down greatly, breakdown section does not need to change moulds and just adjust is ok. And it can cut-down producing period.
Release labor intensity.
Roll forming technology, the caliber is different and propitious for X70,N80 steel strip.
The steel strip is distorted and beared more reasonably, to reduce the rub between the strip and roller, and also reduce the waste of the roller.
It is easier to restore and adjust roller.

2）In Producing Square&Rectangular Pipe

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 arc is Small,and the brim is flat,outlook is regular.
The whole line load is low ,especially the sizing parts.
The width of steel strip is small about 2.4-3% than round into square & rectangle,it can save the consume of raw material.
It adapt 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.
It adapt the combined type roller on the most of the stands,it realize that one set of roller can produce dozens of square&rectangle 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.

3）Produce Parts Of Abroach Cold Rolled Section Steel

Simple abroach cold rolled section steel such as directly formed channel steel, C shaped steel, Z shaped steel.
