Features Of Refractory Materials For Glass Furnaces

The production of refractory materials for glass furnaces is quite differen t from the production of refractory materials for other types of furnaces.
The quality of the refractory materials not only influence the quality of t he glass but also the service life of the glass furnaces.
Most refractory materials for glass furnaces are large in size, which makes the manufacturing technology more complicated. The refractory materials mu st meet the particular requirement of the glass industry.
The glass melt can corrode the refractory materials. The refractory fragmen ts may drop into the glass melt and cause stripes or stones in the glass. I n many cases, when the refractory materials are corroded, bubbles may be fo rmed in the glass melt near the wall. Since the viscosity of the glass melt is high and the density of the glass melt and the refractory materials is similar, the bubbles and the refractory fragments are remained in the glass melt.
The refractory materials for glass furnaces, especially the fused cast AZS, should meet the requirements as follows: 1)Sufficient mechanical strength 2)At the operating temperature, have good resistance to mechanical load 3)Have good corrosion resistance to the components of the batch materials a nd glass. 4)Have low potential of causing stones, stripes, bubbles and coloring. 5)Have good thermal shock resistance. 6)Have low thermal expansion at the operating temperature. 7)Have accurate shape and size and meet the technical criteria.
