内容简介

Measurements of blistering in contact of glass melt and refractory were done. Two different methods were used to detect blistering. To prevent blistering the used porous brick was treated with a substance which creates an oxygen depression in the pores of them. Due to this the surface tension of the glass rises which is shown as extremely lowered blistering up to 50 %. The surface tension of the glass increases in such a level, that the refined bricks show the same low blistering like fused cast bricks. Savings up to EUR 16000 per year for a rolled glass producer are possible.
