Initial practical experience in monitoring refractory material in the glass industry using the SAVEWAY system

Abstract

By means of the SAVEWAY system it is possible to continuously control the refractory material. The measurement of the lining wear is based on the characteristic temperature dependence of the specific electrical resistance of the refractory materials. The advantage of the SAVEWAY system in comparison with other known procedures lies in the areal monitoring of a refractory material. Trough construction areas which are difficult to overlook from the exterior can also be reliably monitored using SAVEWAY. When this system was used in the mineral wool industry it was possible to confirm the remaining wall thickness measurements by means of the SAVEWAY system when breaking out the lining. The results achieved by the glass industry up to now reflect the fact that it is possible to monitor the refractory material by means of SAVEWAY. Modified melting conditions are included in the respective calculations of the remaining wall thickness.
