Description

     Multi-functional Production Line
     This kind of mill can produce round pipe,square and rectangular pipe and some of       abroach cold rolled section steel
 

• ZTF Forming Technology 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.

• Directly Square Forming Technology 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.

• 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.
