Tension Leveler

Product Description

2. It is conducive to improving the anisotropy of the material. The yield limit of the deep-drawn thin plate of low-carbon steel in the longitudinal and transverse directions often has anisotropy. Therefore, when the thin plate is deep-drawn and processed, the thickness of each part of the punched part will be uneven due to the different extension of each part, which will cause the punched part to have skirt-shaped lace defects, thereby increasing the scrap rate. After stretching, bending and straightening, this situation will be greatly improved.

The types and characteristics of straightening machines are as follows:

1. Arch type. Most early straightening machines were like rolling mills, in the form of arches; when multiple straightening machines are used, the arches are connected together.

2. Clamp type. Simple structure, light weight, and convenient adjustment of opening. However, due to the concentrated pressure, it affects the increase of pulling speed.

3. Combined type. As shown in the figure "Combined straightening machine", due to the development of multi-strand continuous casting machines, off-line maintenance is required and it has developed into a combined type.

4. Integral frame five-roller straightening machine. This structural form is most commonly used in small billet continuous casting machines. However, according to the different configurations of the drive rollers, there are several forms: upper roller drive, lower roller drive, and both upper and lower roller drive. Its main structure consists of the frame, transmission device, rollers, cooling and protection devices, etc.
