Customized Size Silica Insulating Refractory Brick for Lightweight Insulation in Henan

 Light silicon insulation brick is made of silica as the main raw material SiO2 content is not less than 91% heat insulation refractory products.The volume density of lightweight silicon insulation brick is 0.9 ~ 1.1g/cm3, and the thermal conductivity is only half of that of ordinary silicon brick. The thermal shock resistance is good, and the starting temperature of the load softening can reach 1600℃, which is much higher than that of clay insulation brick.Thus the highest temperature of silicon insulation brick can reach 1550℃.It does not contract at high temperatures and even expands slightly.
Lightweight silica brick uses crystalline quartzite to be raw material commonly, join flammable material in cooperate material, wait like coke, anthracite sawdust, or form porous structure with gas foaming method.Similar to the production industry of common silicon brick, some mineralizers (CaO, Fe2O3) are added in the ingredients to promote the transformation of quartz, and pulp waste liquid is used as binder to make the brick have a certain strength.In the use of coke or anthracite as combustible, because the ash will be brought into Fe2O3 and Al2O3, the ingredients do not need to add additional iron phosphorus.When the light silicon brick is fired, the strong oxide flame should be maintained before 1200℃ to completely burn out the added material.
The mineral composition of light silica brick is 78% ~ 86% of phosphor quartz, 78% ~ 86% of quartzite and 78% ~ 86% of quartz.The compressive strength of general lightweight silicon brick is 2.0 ~ 9.5MPa, and the thermal conductivity is 0.35 ~ 0.42W/(m·K).Lightweight silicon brick has excellent fire resistance. The softening temperature under load is close to that of dense silicon brick and reaches more than 1620℃. There is only a small amount of residual expansion, and its thermal stability is better than that of dense silicon brick.Therefore, the lightweight silicon brick can be used for a long time at 1500 ~ 1550℃ under the high temperature condition without contact with the slag.

Silica brick is commonly used in glass kiln, which mainly includes two categories: silicon brick and light silicon brick.
A silica,
Silica brick is to point to silica content is in 93% above, the silica that is main component with SiO2 makes raw material, add a few mineralization agent, the refractory material that classics high temperature burns.Its typical mineral composition is as follows: the main crystal phase is scaly quartz and quartzite, and the matrix is quartz glass phase.Silica brick belongs to the acid refractory material, the resistance to acid slag is strong, but by the strong erosion of alkaline slag, easy to contain Al2O3, K2O and other oxides and destruction, CaO, Fe2O3 and other oxides have good resistance performance.The silicon brick has the characteristics of high deformation temperature under load and residual expansion, which guarantee the good air tightness and structural strength of the masonry.However, it has the disadvantage of low thermal shock stability.Silica brick is mainly used in coke oven, hot blast stove and glass furnace and other thermal equipment.According to the different thermal equipment used, the silicon brick can be divided into coke oven silicon brick, hot blast stove silicon brick and glass kiln silicon brick, etc.

Second, light silicon brick
Also known as silicon insulation brick.Light refractories with silica content above 91% and volume density below 1.2g/cm3.The refractoriness and softening temperature under load have little difference with the common silicon brick with the same composition.However, due to a lot of pores, the compressive strength, slag resistance, corrosion resistance and so on are not as good as ordinary silicon brick, but the thermal shock resistance is improved.
The use of fine silica as raw material, its critical particle size is usually not more than 1mm, and the particles less than 0.5mm is not less than 90%.By adding flammable substances in the ingredients or forming porous structure by gas generation method, it is made by firing.It can also be made into non-burning products.Mainly used to require heat insulation or reduce the weight of the kiln without direct contact with the molten material, not by the action of corrosive gas, do not suffer from temperature changes of each part.Used at high temperature, can not contact with alkaline refractory materials.According to the different material, its highest use temperature in 1200 ~ 1550℃.

Glass kiln with light insulation brick according to its different raw materials, can be divided into 6 categories.Its application is most extensive for light silicon brick, diatomaceous earth brick.Light insulation brick has the advantages of good adiabatic performance, but pressure resistance, slag resistance, thermal shock resistance is poor, it can not be directly contacted with glass liquid or flame.
1, light silicon brick.Light silicon insulation brick is made of silica as the main raw material SiO2 content is not less than 91% heat insulation refractory products.The volume of light silicon insulation brick is 0.9~1.1g/cm3, thermal conductivity as long as half of ordinary silicon brick, good thermal shock resistance, the load softening temperature can reach 1600℃, much higher than clay insulation brick.Thus the highest temperature of silicon insulation brick can reach 1550℃.It does not contract at high temperatures and even expands slightly.Lightweight silica brick uses crystalline quartzite to be raw material commonly, join flammable material in cooperate material, wait like coke, anthracite, sawdust, or form porous structure with gas foaming method.
2, diatomite brick: compared with other light insulation brick, diatomite brick has small thermal conductivity.The temperature at which it is used varies with purity.Generally below 1100℃, because the shrinkage deformation of the products at high temperature is larger.When pure diatomite is used as raw material, it needs to be sintered at a higher temperature, and silica is converted into scaly quartz. Lime can also be added as binder and mineralization agent to promote the transformation of scaly quartz during sintering, which is conducive to improving the heat resistance of the product and reducing the flushing shrinkage at high temperature.
3, clay insulation brick.Is made of refractory clay as the main raw material Al2O3 content of 30%~48% heat insulation refractory products.The production technology adopts the method of burning out and adding material and foam method.Light clay insulation brick has a wide range of uses, mainly used in a variety of industrial furnaces do not contact melt and no erosion of other role of insulation layer refractory materials, the use of temperature of 1200~1400℃.
4, alumina insulation brick.The products have high refractoriness, good heat shock resistance, and are commonly used as high temperature heat insulation layer for kiln.The operating temperature is 1350~1500℃, and the operating temperature of high purity products can reach 1650~1800℃.The heat insulation refractory products are mainly made of fused corundum, sintered alumina and industrial alumina.
5. Lightweight mullite bricks.Mullite as the main raw material made of heat insulation refractory products.Mullite insulation brick has the advantages of high temperature resistance, high strength, low thermal conductivity and direct contact with flame. It is suitable for lining of various industrial furnaces.
6, alumina hollow ball brick.Alumina hollow ball brick is mainly used for a long time below 1800℃.It also has good chemical stability and corrosion resistance at high temperature.Compared with other light insulation bricks, alumina hollow ball brick has the advantages of high safety temperature, high strength and small thermal conductivity.The bulk density is also 50%~60% lower than the same composition of dense products, can withstand the impact of high temperature flame.
