Silica Brick - The best Silica Brick from China Zhengzhou Shixing Refractory.

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. It is widely used in coke oven, hot blast furnace, glass furnace and carbon furnace.

Applications:
The silica brick can be widely used in coke oven, hot blast furnace, glass furnce and carbon furnace. In glass industry, it is mainly employed to build the doghouse crown, suspended wall of channel, top crown and inlet sealing. In metallurgy industry, it is adopted as the nozzle brick.
