Henan Xinmi factory silica refractory bricks or silica firebricks for glass kiln, coke oven or hot blast stove

Silica firebrick is a kind of acid refractory material consisting mainly of scale quartz, calcite and a small amount of residual quartz and vitreous phase. Silica content in this brick is above 94%. True density 2.35g/cm3. It is resistant to acid slag. Higher high temperature strength. The initial temperature of load softening is 1620~1670℃. In high temperature for a long time without deformation. Low thermal shock stability (water heat exchange is 1~4 times) with natural silica as raw material, plus an appropriate amount of mineralization agent, to promote the conversion of quartz in the billet into, scale quartz. It is slowly fired at 1350~1430℃ in reducing atmosphere. When heated to 1450℃, about 1.5~2.2% of the total volume expansion, the residual expansion will make the cut joints close, to ensure that the masonry has good air tightness and structural strength.

Functon:
Silica Bricks, also called silica refractory bricks or silica fire bricks, are acid refractory bricks products which have good acid slag resistance ability. If you want to buy silica bricks for your glass kiln, coke oven or hot blast stove.The silica brick is mainly used for the partition wall of the coking chamber and combustion chamber of the coke oven, the regenerator and the slag chamber of the steel open furnace, the soaking furnace, the refractory material of the glass melting furnace and the firing kiln of ceramics, etc. Load-bearing parts. It is also used for high temperature load-bearing parts of hot blast stoves and acid open hearth furnace roof.

Silica firebrick technical data
Silica firebrick is an acidic refractory material with good resistance to acid slag erosion. Its softening temperature under load is as high as 1640～1670℃, and its volume is relatively stable under high temperature for long-term use.

Main characters of silica firebrick
(1)High refractoriness under load.
(2)High heat conductivity.
(3)Good thermal shock resistance.
(4)Solidity stable of capacity in high temperature.

Usage
1.Silica firebrick for glass furnace
Silica bricks for glass kilns refer to siliceous refractory products used in high temperature parts of glass kilns (not in contact with molten glass). The tank kiln is a large and complex masonry made of various refractory materials, and its vault mostly uses silica bricks. Some glass kilns also use silica bricks for the vault and checker bricks of the regenerator
2.Silica firebrick for hot blast furnace
(1) Under long-term high temperature and load conditions, the volume is stable, the high temperature creep rate is low, and it can be used continuously for one or two blast furnaces;
(2) Good performance above 600℃ The thermal shock resistance. Adapt to the variability of the temperature of the hot blast stove, keep the bricks and masonry intact;
(3) The chemical resistance is better
than clay bricks and general high alumina bricks.
(4) The thermal conductivity of silica bricks is larger than that of clay bricks and high alumina bricks, which is conducive to shorter Time to store and release heat.
3.Silica firebrick for coke oven
Silica bricks for coke ovens are mainly silica bricks, accounting for about 70% of the total refractory materials. It is the most suitable refractory brick for the furnace wall of the coking chamber. In the coking process, at the same time and with the same coal contact area, silica bricks can transfer more heat from the combustion chamber to the carbonization chamber, thus saving energy. The furnace wall itself also has a heat storage function.
