Audit: increase of line load in the press section

Audit: increase of line load in the press section

Fewer breaks due to greater wet strength

The audit is aimed at increasing the line load in the press nip and therefore increases the dry content and the initial wet strength of the paper web. It reduces the number of breaks and increases productivity.

The potentials of the components are utilized to increase productivity. In a finite element analysis of the components, the limiting elements are identified and suggestions for optimization are established. The optimization potential of the entire press section is highlighted with the latest calculation methods and use of the most modern roll covers and clothing. Increased line load can result in higher speed in the press section or a lowering of steam pressure providing significant energy savings.

Among the factors examined in the audit are roll design, compression system, machine frame and drive power of the press section. Existing component potentials are utilized to increase the line load.
