Typical Application

        Lightweight silica brick is mainly used for thermal insulation or reduce weight without direct contact with molten material, gas is not subject to erosion, don't suffer from temperature leaps kiln parts. Use at high temperatures, can not contact with alkaline refractory materials. According to the material is qualitative different, its highest use temperature at 1200 ~ 1550 ℃.

Advantage of Light Weight Silica Brick

 

Lightweight silica brick is lightweight refractory with silicon dioxide more than 91%, the volume density of 1.2 g/cm3 .Refractoriness and refractoriness under load and the composition of the same common silica brick. But due to the porosity, so the compression strength and slag resistance, corrosion resistance and other than ordinary silica brick, and thermal shock resistance is improved.

Q:How to improve the thermal conductivity of the coke silicabrick rate?
The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).
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:Why is the new trend of the high thermal conductivity of silica brick
The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.
Q:The production of brick, the ingredients of why join the waste brick?
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
Q:Such purpose and scope please give me detailed points thank you because I am learning stage
Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:What are the materials for refractory materials? What are their names?
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:The difference between clay refractory bricks and refractory brick in the application.
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
Q:Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.
Q:Which material is good for furnace refractory?
Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
