SIROLL SIFLAT

Contactless flatness measurement for high-quality rolled strips

The SIROLL SIFLAT system involves periodic excitation of the strip and measurement of the excitation amplitudes across the strip width. Excitation force is applied by creating a vacuum between the strip and a sensor plate below the pass line of the mill stand. A modulator periodically opens and closes an air shaft to achieve periodic excitation of the strip, while the strip’s excitation amplitude is measured by contact-free eddy current sensors.

SIROLL Edgewipe

A flexible system for effective control of strip edge dryness

The SIROLL Edgewipe system incorporates all the necessary features for effective control of strip edge dryness. Where coolant is carried over to the exit side of the mill, standard air blow-off systems remove excess fluid from the top and bottom surfaces of the strip but not from the extreme vertical edges. Strip dryness is achieved by blowing the beads of fluid off the strip edges and removing it completely by drawing the resulting plume of fluid through an air mover away from the strip.
