7-15The main component of silica brick :
Silica refractory brick is a refractory product with silicon dioxide as its main component and its content of more than 93%. It uses quartz rock as raw materials, adds mineralizers and binding agents, and is made at high temperatures at high temperatures. Its mineral composition is Sylphy, and a small amount of residual quartz and high -temperature glass are coexist. For coke furnaces, hot air furnaces, glass kiln, etc.
Silica brick are acidic refractory materials, strong anti -acid residue erosion capacity, load weight softening temperature is as high as 1670 degrees, high temperature volume is stable, long -term use does not deform, and silicon dioxide content is more than 94%. Thermal equipment lining.

Silica brick is an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases
Silica brick: an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Its silica content is more than 94%, it has anti-acid slag erosion performance, high high temperature strength, high load softening temperature, long-term use in high temperature flower wells without deformation, but low thermal shock stability (heat exchange in water is 1-4 Second-rate).
Silica bricks for coke ovens are siliceous refractory products used for building coke ovens with tridymite as the main crystal phase. Coke oven silica bricks are used to build regenerator walls, ramps, combustion chambers, carbonization chambers and furnace roofs of coke ovens. Silica brick is an acid refractory material with good resistance to acid slag erosion. The softening temperature under load is as high as 1640-1670 °C, and the volume is relatively stable in long-term use at high temperature.
The refractoriness of clay bricks is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. Because in addition to the high refractory mullite crystal, the clay brick also contains nearly half of the low melting point amorphous glass phase.
Silica brick: an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Its silica content is more than 94%, it has anti-acid slag erosion performance, high high temperature strength, high load softening temperature, long-term use in high temperature flower wells without deformation, but low thermal shock stability (heat exchange in water is 1-4 Second-rate).
The refractory pre -production is the category of irregular refractory materials, also known as the prefabricated block of the pouring materials, and the irregular refractory prefabricated block.
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
