Use and technique

Modern finishing and inspection lines are run at high speed with tight tolerances.

The essential advantage of our measuring systems in comparison with conventional methods lies in their fast, continuous, non-contact, real-time acquisition of high-precision measured values.

In parallel with the continuous development of technological processes and plant automation, quality demands also increase steadily.

Thickness measurement
Cold strip

For example,

- Mechanical properties, such as formability and yield strength
- Dimensional consistency over the width and the full length of the strip
- Strip flatness and surface quality

are decisive factors in making and finishing high quality goods both in the semis plant and in the plant producing
finished products.

Particularly in the steel, aluminium and other non-ferrous metal industries, flat hot and cold rolled strip belongs
to the class of « intelligent products », whose quality plays a role of ever-increasing importance.

We have accepted this challenge from industry, and are contributing to an effective increase in productivity with
our high precision non-contact measuring systems. In selecting components for these systems, we do not consider
only technical and economic aspects; all components must also be environmentally friendly.

Measured variables

Our measuring systems determine precisely, reproducibly and reliably the following product characteristics:

- Strip thickness
- Strip profile
- Strip width

- Strip flatness
- Temperature and temperature variation across the strip width
- Strip speed and length

Characteristics

Our systems have, among others, the following performance characteristics :

- Measurement accuracy < ± 0.1%
- Measurement time constant to 1 ms
- Continuous non-contact data acquisition
- Real Time System
- High reliability

- Radioisotope and X-ray technology
- Fast, high precision detectors
- High performance computer systems
- Robust, heavy duty rolling-mill construction

Measuring points in different explanations

The following overview shows you a few examples from a multitude of possible applications in cold rolling.

Measuring system for determing the
centreline strip thickness

System design:
Fixed measuring head
Movable measuring head

Measuring system to determine the
centreline strip thickness and traverse
profile independently of one another

System design:
Movable meaurement points with a
traversing measuring head.

Measuring system to determine the
centreline strip thickness with continuous
simultaneous multi-channel measurement
of the edge profile (Edge Drop)

System design:
Movable measuring points with two
traversing measuring heads following the
strip edge and one measuring head fixed
over the strip centreline.

Measuring system for determining the
centreline strip thickness with
simultaneous measurement
of traverse profile corrected for the strip contour

System design:
Movable measurement points with either a
fixed or an oscillating C-frame carrying two
fixed measuring heads.
