A brief introduction of Refractory thermal expansion fire bricks for Blast
Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw material is natural silica sand whose SiO2 content should be more than 96%. The higher SiO2 content in silica sand, the higher temperature silica bricks resist. Silica bricks are used in the roof and superstructure of glass melting tanks as well as for hot repairs.
Our Furnace thermal expansion fire bricks advantages
--Adopts high quality silica and advanced technology, our Silica checker brick 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 good 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.
