Hydraulic and mechanical recalculations and recommendations

Excellent paper quality and maximum productivity can only be achieved through flawless functionality of the headbox.

Voith is a trusted partner for future planning as to the utilizability of the headbox and its conversion possibilities. The design review by Voith provides feedback on whether existing headboxes are suitable for planned operating conditions in the future.

With increased production speed or throughput quantities in the headbox, higher pressures and faster flow speeds arise. They can lead to undesirable deformations which in extreme cases cause component failure and lead to flow effects that negatively influence paper quality.

Thus, with a planned increase in production speed, a check on component stress and a hydraulic recalculation should be carried out.
