AMETEK Land Float Glass Plant Behind the Lehr App

TEMPERATURE MEASUREMENTS IN THE FORCED AIR-COOLING ZONES DOWNSTREAM OF THE LEHR ON A FLOAT GLASS PLANT
The cooling rate and homogeneous thermal distribution across the width and length of the glass ribbon within the annealing lehr and forced air cooling zones are essential to float glass quality .
Frequent , accurate measurements of the temperature profile are necessary to reduce stresses in the glass and to optimise the cooling rate over the entire process length . With the development of the LSP- HD linescanner , AMETEK Land provides a non-contact infrared solution for accurate temperature-crossprofile measurements that optimise the annealing process and minimise thermal variations across the width of the glass , making production of thinner or thicker glasses possible .
The LSP-HD solution can cover the different locations of the lehr . The hottest locations from A to C can be covered by the LSP-HD float line mounting with the LSPHD 5FL , and the coldest from location D to E with the LSP-HD 60 or LSP-HD 5 . For the typical location F , where the temperature of the glass ribbon could be below 100 ° C , the LSPHD 60 will be used ; this is the typical application described in this document .
