Based on SEFPRO R&D knowledge on microwave technology to analyse internal structure of AZS fused cast soldier block, new tools have been developed to be able to prevent blind area obtained with conventional radar wave's analysis on small thickness tiles. The advantages of this new technique is to obtain reliable internal structure pictures of AZS fused cast tiles used in bottom paving application for containers or float glass furnaces. The strength of this microwave technology allows high corrosion resistance. Combined with tight joint machining and the double layer refractory mortar solution, it constitutes a reliable high performance bottom solution well adapted to specific conditions such as high insulation to prevent heat loss, electrical boosting or extra white glass melting.
