Sendzimir 20 High Rolling Mill

The overall frame structure of the sendzimir 20 high rolling mill has the advantages of great rigidity, bearing the rolling force along the entire width of the rolling mill through the backing bearing, and therefore the longitudinal and lateral dimensional accuracy of the strip is high. Therefore, it has been widely used in the cold rolling industry. The 20-roll mill is suitable for strip processing of stainless steel, silicon steel, carbon steel, non-ferrous metals, etc. The equipment has the characteristics of high speed, stability, good surface quality, and good shape.

Characteristics of Rolling Mill

1. The frame with integral casting has high rigidity and the rolling force acts radially on each section of the frame.

2. The work roll has a small diameter and the pass reduction rate is high, up to 60%. Some materials can be rolled into very thin strips without intermediate annealing.

3. It has axial and radial roll shape adjustment, roll diameter compensation, rolling line adjustment and so on, and adopts hydraulic screw-down and hydraulic AGC system. Therefore, the product has good shape and high dimensional accuracy.

4. The equipment is light in weight and the quality of the mill is only one third of the four-high mill of the same specification. The rolling mill has a small outer shape and requires less capital investment;
