This kind of mill can produce round pipe,square and rectangular pipe(direct to square or round to square) and some of abroach cold rolled section steel

1)      ZTF Forming Technology Used In Produce Round Pipe

l  Save 60% tooling cost

l  Before the closed pore, one set of rolls can be used to produce lots of sized round pipe within the range. All the rolls before this section can be shared use and no need to change.

l  Limite production time and labor cost

l  Easy to restore rolls

l  Convenient to restore and adjust.

2)      Directly Square Forming Technics In Produce Square&Rectangular Pipe

l  Compared with ared with round to square forming technology, square to square technology can make better shapes of angles for cross section, smaller semidiameter of inner arcis, flatter brim, regular outlooks.

l  Ease more burden of the whole production line, especially for the sizing section.

l  2.4-3% strip width shrinkage than round square forming method, so saving more raw materials

l  By advance multi-point bending, avoiding the axial force and side abrasion, reducing the forming step and ensuring the quality, meanwhile reducing power wastage and roll abrasion.

l  By combined rolls, one set mould can be used to produce lots of square and rectangular pipes for different specifications. This can decrease the storage of rolls, save 80% roll costs, fasten the bankroll turnover, shorten developing time for new lines.

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. The rolls can be basically shared with directly square forming technology.
