20-Roll Sendzimir Mill


The Sendzimir mill is a reversible rolling mill specifically designed for processing difficult-to-deform metal sheets and coils, such as stainless steel, silicon steel, titanium, and titanium alloys. Its roll arrangement differs from that of conventional two-high and four-high mills, enabling smaller deflection of the work rolls under rolling force and ensuring more uniform distribution of the rolling force across the mill frame. The Sendzimir mill consists of a mill frame, roll-down mechanism, crown adjustment device, first intermediate roll gap adjustment mechanism, pressure plates and side guides, sealing rolls, X-ray thickness-measuring equipment, and guide rolls, among other components.

The Changshuo Senjimil rolling mill has the following main features:

  1. The main frame is imported equipment, and the tension rollers are equipped with dual motors that can seamlessly switch between single- and dual-motor operation, ensuring rolling stability.
  2. The work roll has a small diameter (40 ± 0.3 mm) and generates high rolling force, making it more suitable for foil rolling.
  3. Use titanium-rolling-specific rolling oil and replace the filter element every three months to ensure that no foreign particles enter during the rolling process.
  4. Solid sleeves are used for the front and rear tension rollers, ensuring more stable tension control during finish rolling.
