Multi Rolls Straightening Machine

1. Composition of 23 rolls straightening machine

· Figure 1: ① uncoiler, ② entrance turning, ③ entrance tension roller, ④ triple bending, ⑤ 23 roller straightening, ⑥ export of tension roller, ⑦ exit turning，⑧ Coiler. Among them, multiple bending and 23 rolls multi rolls straightening are the key equipment.

· The stretching bending straightening machine is equipped with 8 sets of tension rollers. The tension rollers are divided into two groups according to the arrangement of the units. They are the inlet tension roller group and the outlet tension roller group, respectively, and the tension between them is straightening tension. It is combined with the uncoiling tension and the winding tension to form the three section tension control of the unit. The 6# tension roll speed is the base speed of the unit, and the speed difference of the unit before and after the straightening section can realize the control of the unit elongation. The unit's 4# unit is a triple bending unit, and the 5# unit is a 23 roll multi roll Straightener. The function is to strengthen the bending stress release.
