Tactel - Import export

The systems of the VBP Series are offline tactile measuring systems which evaluate the cross-profile of the strip – irrespective of the alloy – on strip samples cut from the coil. They are frequently used in hot rolling mills for aluminium and steel, because it is here that the cross-profile is set for all the subsequent uses of the strip; the cross-profile measurement is of great significance at this point. During rolling, X-ray gauges are generally used which operate irrespective of the alloy and which have limited precision due to the high temperatures at the measuring point and due to the other ambient conditions. The high-precision cross-profile measurement is then performed offline using the VBP systems with their measurement accuracy of down to ± 1 µm. In this way the mill operators can achieve a high process reliability.
