Product Description
High Alumina Brick/Rrefractory Brick/Fire Brick
High alumina brick refers to fire brick containing Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on. | |

Welcome to our factory.^_^
- Q: The introduction of silica brick
- The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
- Q: Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.
- Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- Q: Why will expand when heated brick
- After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
- Q: What is acid refractory?
- Refractory materials are mainly quartz glass products, combined with fused quartz products, silica brick and unshaped refractories. Semi siliceous refractory materials are generally attributed to this category. As for fireclay refractories, they are also classified as semi acidic or weakly acidic refractories. Also, zircon refractory and silicon carbide refractory for special acidic refractory materials are also classified into this category.
- Q: How much is the highest melting point of silicon?
- . True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. The total volume of heating to 1450 DEG about 1.5~2.2% expansion, the residual expansion will make cutting seam sealing, ensure masonry tightness and good structure strength, so that the brick load softening temperature will reach 1750 degrees Celsius above 1620 degrees in the case of the highest melting point.
- Q: Semisilica brick, clay brick, high alumina brick and what is the difference?
- The share of A12O3 and SiO2 is different
- Q: What role does silica play in refractories?
- Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
- Q: Can not use it two brick
- The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
- Q: Brick
- Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
- Q: Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
