INTELLIGENT SINGLE POINT SENSORS
INGOT, Thickness Measurement
Many aluminum ingot processors do not have a suitable method of
on-line quality control detecting surface flaws. Improvements need
to be made to achieve more accurate measurement in a variety of
situations. Using calipers is slow, and cannot cover a large surface
area of the ingot. Yields can be increased substantially by planing
the ingot to the correct thickness. Planing too heavily results
in lost production. Plane too light and surface pits can turn out
to be large flaws after the product has been rolled down to a very
thin sheet, requiring a full stop in the production line.
Using an array of up to 40 SPR-02 Single Point Sensors, measuring
thickness profiles on-line with complete accuracy, in front of
the planer, will determine the thinnest point on the ingot.
The information is then fed to the control system, and into the
operators booth, delivering an instantaneous picture of variations
in thickness of the slab. The planer is then set to the minimum
thickness of the ingot, and the absolute minimum amount of aluminum
SPR-02 sensors used as laser micrometers, deliver instantaneous and
continuous information, as well as compile information on shifts,
allowing supervisors more time to focus on other areas. Higher recovery
rates can be achieved, delivering increased efficiency and increased
profits. Down time, due to inconsistent product, further down the
production line is also reduced or eliminated.
