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. | |

Our Team
Welcome to our factory.^_^
- Q:The United States of our brick anti-dumping duties?
- . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.
- Q:Physical solid waste disposal
- The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
- Q:The specific content is what gb/t2608-2012 brick
- Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
- Q:Can iron oxide be used as refractory material?
- Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.
- Q:Brick
- The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on.
- Q:Physical solid waste disposal
- The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
- Q:How to improve the thermal conductivity of the coke silicabrick rate?
- To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
- Q:What is the main material of silica brickIt's common, the kind we see so often!
- An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
- Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
- Brick, high thermal conductivity has been greatly improved in terms of morphology, crystal structure, physicochemical index. The structure and morphology of high thermal conductivity of silica brick,Structure and morphology of high thermal conductivity and the traditional brick brick magnified 20 times were compared, high thermal conductivity silica pore size distribution is more uniform and finer.
- 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.
