Metso's new PaperIQ Select raises the bar for online paper analysis and quality upset control
Metso Automation has introduced a new,
ground-breaking paper quality control system, called PaperIQ Select. The system
has extended online quality and process analysis functions and paper machine
disturbance control capabilities. These enhancements are provided by new paper
quality measurements, online machine direction (MD) and cross direction (CD)
spectral analysis and a completely new approach to managing control of the
scanning function.
This revolutionary selective and adaptive paper web
measuring technique suits the different dynamic measurement and control
requirements of steady state production and machine upset conditions like
breaks and grade changes, and precision paper edge analysis. All this is
possible with new intelligent scanners, ultra fast measurements and data
collection. The new IQScanner-i is designed for harsh machine applications,
up to and beyond 11meters in trim width.
End of traditional
scanning
The new adaptive, situation-based patented scanning
technique replaces and vastly improves the analysis and control capabilities of
the single speed, front to back scanning action of traditional QCS systems.
Now, it is possible to have variable scanning speeds and scan widths as well as
MD and CD control responses to suit normal production conditions or upset
states. The result is less broke because of faster start-ups and grade changes,
and quicker recovery from breaks and coating blade changes.
Fast
on-line paper analysis
Based on selected variability triggers, the
system automatically selects an analysis mode. MD paper variation can be
reported in several frequency bands by the spectral analysis capability built
into the system. Paper quality variability can therefore be related to upstream
process variations, and corrections can be made. The variability analysis can
be used to benchmark machine variability for continuous improvement programs.
The system also provides high resolution, high speed analysis of the critical
sheet edge areas, for better edge quality.
Full selection of
innovative measurements
The new PaperIQ Select includes
measurements for weight, ash, moisture, spectral color, laser and magnetic
caliper, optical printing surface properties, image analysis formation,
porosity, reel micro-diameter and hardness, web tension profile, plus high
speed IR detection of wet end moisture levels.
One of the totally new
features is full utilization of multi-purpose infrared detection. The same
multiple wavelength spectral analysis technique can be used to selectively
measure moisture, opacity, fiber weight and ash levels, even silicon. The types
of measurements required can be selected for the application. For instance, a
nuclear basis weight sensor is not mandatory for tissue grades.
