Silica Brick For Glass Kiln

►Description
Adopts high quality silica and advanced technology, our silica bricks enjoy the advantages of high purity, long service life, good thermal conductivity, high refractoriness under load, and good creep resistance. In addition, it has accurate size tolerance, pure color and luster appearance. Because of the bad thermal shock resistance of silica brick, it is mainly used in the continuous operating furnace. Supporting the use of other high quality refractories, our silica brick can extent the service life of float glass furnace to 8 years and double the service life of bottle glass furnace.

►Applications
This Super Duty Silica bricks can be not only widely used in the roof and superstructure of glass melting tank as well as for glass furnace repairs, but also used in the flue, regenerator, neck area and cooling tank for the glass furnace.
