METHOD AND DEVICE FOR REGULATION OF RADIATIVE COOLING SECTIONS ON A SHEET GLASS LEHR

摘要

The invention relates to a method for regulation of radiative cooling sections on flat glass lehrs provided with a plurality of heating elements and a plurality of cooling elements in the direction for transport of the glass, each heating or cooling element being made up of a plurality of distinct radiative sections across the web. According to the method the factor (Sj) of the regulation body (TIC) for the capacity for heating or cooling of each radiative section is weighted (Sj') by a regulation system (R) for a filter called a "matrix filter" which weights the influence of the signal provided by the measuring body (4) for the temperature of the glass taking into account the influence on the heating or cooling of the glass by the adjacent radiative sectors according to the geometry of the layout of the radiative sectors with relation to the point of measurement of the glass temperature.
