Measurement of the temperature distribution in glass melt gobs after cutting glass melt gobs after cutting
An apparatus for the measurement of the surface temperature distribution of a glass gob has been tested. Significant temperature variations are measured along the gob length due to heat loss by radiation, and in the radial direction due to the influence of the feeder. The detection of a complete temperature distribution requires several minutes, within this period the state can be assumed constant. The position of the measuring spot influences the result, a 5 mm deviation results in a measurement error of about 1 K. The use of a cavity radiator significantly improves the accuracy of the temperature measurement. This system forms the basis of a planned programme of operative measures designed to influence the temperature distribution in the gob.
