Silica Brick for Glass Furnace Silica Refractory Material
The Description:
Silica brick for glass melting furnace) refers to the silica refractory products used for laying high temperature parts of glass tank kiln (not in contact with glass liquid). Pool kiln is a complex large masonry made of various refractory materials, its vault mostly uses silicon bricks, parapets, and small furnaces have all used silicon bricks, and some have been replaced by fused zirconium corundum or β-alumina products since the 1970s. Some glass kiln regenerator vault and lattice bricks are also made of silicon bricks.

The properties of glass kiln silicon brick are:
(1) The high temperature volume is stable, and the furnace body will not change due to the temperature fluctuation surface. Due to the high load softening temperature of silicon brick, the creep rate is small, and the glass kiln can maintain the furnace body without deformation at 1600ºC, and the structure is stable;
(2) No pollution to liquid glass. The main component of silicon brick is SiO2, in use, if there are falling blocks or surface droplets, does not affect the quality of the glass liquid;
(3) Chemical erosion resistance. The silicon brick of the upper structure is eroded by the gas containing R2O in the glass ingredients, and a smooth metamorphic layer is formed on the surface, which reduces the erosion rate and plays a protective role.
(4) Small volume density, can reduce the weight of the furnace body.
