The main problems faced by Glass Industry Refractory Materials is the development of low temperature melting. Arsenic-free material melting process, the whole oxygen combustion technology and the development of electric melting technology, refractory material to make more stringent requirements.

In recent years, the life of glass melting furnace has been greatly improved, the production of flat glass float production line up to 10 years, ordinary glass melting furnace life of 5 to 7 years, special glass melting furnace life of up to 2 years , So the refractory material must have high resistance to erosion, the impact on the glass quality is small, the environment does not cause pollution, quality and energy saving effect is obvious and other functions.

Glass Industry Refractory Materials

In order to improve the quality of glass, refractory materials in addition to the use of the traditional No. 1, No. 36, No. 41 zirconia corundum brick (AZS), a 94% zirconium oxide casting brick (ZFC) has also been developed. This high zirconia cast brick has better performance than AZS bricks. Such as less glass phase, anti-glass erosion, greatly reducing glass products such as bubbles, stones and other defects. Therefore, this cast brick can be adapted to a variety of glass melting, such as aluminum silicate glass, electronic glass and boron - silicate glass.

In order to adapt to the development of electrofusion technology, the researchers developed a 90% zirconia-containing cast brick (ZFCR), the high temperature resistivity is ZFC cast brick 10 times. Thus showing excellent resistance to erosion.

Glass Industry Refractory Materials

The Shixing company is adopted on producing high quality Fused Cast AZS Block used in glass furnaces. Established to produce series of shaped blocks Fused Cast AZS-33# Block, Fused Cast AZS-36# Block and Fused Cast AZS-41# Block with annual production capacity 20,000 tons/year. New materials production zone is equipped with two high-temperature shuttle kilns, mainly producing Zircon Brick, Silica Brick, Magnesia Brick, etc.
