Specification:

Product characteristics, combining high alumina brick P and phosphate and nitrate high alumina brick wear-resisting brick PA in yangquan super bauxite clinker as aggregate, respectively using nitrate and phosphate as binder, after high pressure forming, the temperature in the processing and into. Product has good abrasion resistance, good resistance to spalling at the same time also has the potassium sodium sulfur chloride alkaline salt erosion resistance, such as performance, is widely used for preheating zone, decomposition and wicket, cooling machine, etc. Special phosphate combined with high alumina brick TP is on the basis of the phosphate combined with high alumina brick, by adding additives to improve the refractoriness under load, high temperature performance of products, widely used in the transition zone of middle and small dry kiln and the wet kiln and the calcining zone, can also be used in large dry kiln seat belt cover, wicket, cooling machine, etc.

Cement kiln with high alumina brick

Q:High alumina brick 80 with which high aluminum cement?: In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.

Q:What is the high temperature limit of refractory bricks and refractory soil?: Refractory bricks are stone powder and clay paste. They are fired in a kiln of 1300 degrees. The upper limit is 1500 degrees above normal pressureRefractory bricks - refractory materials of a specified shape and size.

Q:In 2016, a few of the traditional refractory materials will be able to survive: From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;

Q:What are the categories of bricks?: In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:How to reduce the harm caused by two times mullite in high alumina refractory material: Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.

Q:Aluminum content 38, silicon content 55 What refractory bricks?: Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite

Q:What are the alloy wear resistance materials?: Alloy wear-resistant materials from different manufacturers different components in Beijing Naimo company as an example, the following alloy wear resistant material:1: Ni Cr alloy wear-resistant material2: chrome carbide wear-resistant material3: high manganese alloy wear-resistant material4: tungsten carbide alloy wear-resistant material5: nickel tungsten alloy wear-resistant material

Q:Does the chimney have high acid resistance?: The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.

Q:The difference between aluminium refractory and magnesia refractory: Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.

Q:Density of high alumina bricks: Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
