Electro-fused zircon bricks & blocks for glass & frit furnaces according to customer requirements;
It is widely used in glass furnaces especially produce high quality glasses as side wall, running area, spout support sections.
Zirconia fused-cast refractories have excellent anti-corrosion and thermal shock resistance. Resistance to corrosion of liquid glass is The most important characteristics.
