Typical measuring reports for strand guides using templates or perpendiculars are handwritten. A feeler gauge or micrometer gauge is used to measure the distance from the template or perpendicular to the copper plate or to the roller at a single measuring point, and the operator then takes the set point value from the drawing. He must now calculate the difference manually in order to obtain the roller setting value which is entered in the report.
This method implies a high error potential. Every operator has much influence on the correctness of the measurement, and mistakes can occur during the measurement, e.g. calculation errors, reading errors when measuring, errors when reading the set points in the drawing, or reports that are simply illegible.
All of these problems can be solved with HD LASr [strand] because it records the measuring information automatically, knows all set points, and automatically also displays all deviations from the nominal position. Reliable measuring reports (Figure 4) are available at any time, automatically generated, clear, legible, reliable and incorruptible. Within a short time, the operator holds the scan result in his hands and can initiate the necessary measures for re-aligning the strand guide with the optimum strand contact line and the correct roller gap.
Furthermore, HD LASr helps documenting the measuring work. But achieving a high-quality alignment is not the only important thing to do – it must also be documented and stored. Up to now measuring reports were often stored in paper form. This often made finding or analyzing measurement data quickly more difficult.
With HD LASr a clear and full overview of your digital measuring reports is always available. Even with a large number of measurements you can make a fast and intuitive search for your report, right down to a single measuring point. Color displays used to highlight the measuring progress allow information on the alignment quality to be obtained directly and help you to analyze your measurement data easily.
