It can produce round pipe with ZTF forming technology ,Square and rectangular pipe with direct square forming technology,and also some simple open section steel.
● Cut down roller changing time, breakdown section does not need to change rollers . And it can cut-down producing period.
● Saving about 60% cost on the rollers
● Release labor intensity.
● Roll forming technology, the caliber is different and propitious for high steel grade such as X70,N80 .
● The steel strip is bended more reasonably, to reduce the friction between the strip and roller, and also reduce the waste of the roller.
● It is easier to restore and adjust roller.
● The width of steel strip is small about 2.4-3% than round into square & rectangle,it can save the consume of raw material.
● 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.
● 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.
Simple abroach cold rolled section steel such as directly formed channel steel, C shaped steel, Z shaped steel.
