- Q: Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q: Can anyone tell me the requirements of the refractory masonry?？
- Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
- Q: Kinds of refractory mortar
- It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
- Q: Who knows the model of fireproofing materials?
- There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire?rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.
- Q: Where is the distributing center of refractory materials in China?
- Refractories industry is one of the pillar industry of Gongyi City, the city's existing more than 300 refractory enterprises, the annual output value of 10 billion yuan, accounting for three of the city's GDPA share of the domestic market share of about 30% of refractories. Production of stereotypes, not stereotypes of two kinds of aluminum, magnesium, silicon and carbon four series of more than 1000 varieties of products, covering the whole country, and exported to Europe and other regions, is one of the Chinese refractory base. Yongan Road Subdistrict Office area is the center of the hinterland of refractories industry, Yongan is the theme of economic development, Chinese, Gongyi refractory chemical professional market, location, close to the aisle 310, Henan Provincial Highway S31, Yongan road and the construction of the Gong Teng speed transportation is very convenient.There is a good space for development and a relaxed business environment. Very conducive to customer management and development, is conducive to the full enjoyment of preferential policies in Gongyi, backed by trees good shade, head blue sky good development.
- Q: What effect does aluminium powder play in refractory bricks?
- Aluminum powder is the main temperature resistant material ~ ~ ~ ~!
- Q: What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
- The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
- Q: Ask some questions about refractories
- Application: it is suitable for blast furnace tapping system.
- Q: What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q: what textures of furnace refractories are good?
- The common one uses the ordinary aluminous fireclay brick and GB / T 3994-2005 insulating fireclay brick. The ones with excellet texture are high-grade thermal insulation refractory brick and GB / T 3995-2006 high alumina insulating firebrick, whose model is A13, the texture is alumina, A13 50u, advanced heat insulating brick B5; intermediate heat insulating brick B2, and so on. Dolomite brick: The formation of coating is of good performance and corrosion resistance, but to some extent, there exsits the f-CaO in the brick, which is easy to hydrate, and hard to transport and storage, thus less using in the production. Magnesia-chrome brick: The formation of coating is good, so it is widely used for burning zone, but the disadvantage is poor thermal shock resistance, coupled with the highly toxic positive Hexavalent Cr, so the international countries that produce and use the magnesia-chrome bricks are gradually reducing. The production unit using this brick now, please find alternatives as soon as possible.
