$High Alumina Refractory Fire Bricks for Kilns$

Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?: Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.

Q: What is the difference between corundum and high alumina??: The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.

Q: What is the price of the latest thermal insulation material?: Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.

Q: What are the requirements for Rubble backfill height?: 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

Q: What is the standard size of high alumina brick?: Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.

Q: How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

Q: What kind of material is the general metal case?: Generally speaking, the outer surface of the case is usually made of a steel plate of more than 1 millimeters. The thickness and the material of the steel plate are directly related to the rigidity of the case, as well as the capability of sound insulation and anti electromagnetic radiation. The regular manufacturers of the chassis plate thickness not less than 1.3mm, but there are also some small manufacturers with a thickness of only about 1mm steel, we do not need the ruler to the amount, as long as you put him up, the more weight in the same volume of the chassis is better, in addition, we can also use the finger bomb case shell. If you can hear the crisp percussion sound proof of the casing plate is thin and brittle, if you hear is relatively dull and heavy sound that the chassis material must be good, good general steel plate coated with a layer of thin zinc (bright part), so it can withstand high strength, impact resistance, hardness high elasticity. The frame parts of the chassis are made of high quality materials with high hardness. They are bent into angle shapes or strip shapes. We can shake the chassis frame of the case by hand. Good chassis should be relatively stable, and inferior chassis light is easy to shake. When choosing, we should also pay attention to the outer edge of the case and the edge of the inner bracket. Whether the incision is smooth or not, a good case will not appear in the case of rough edges, sharp edges, burrs and so on. While the poor case appears above phenomenon, often appear when installing the blood splattered". Generally speaking, the chassis must go through the corresponding grinding process before leaving the factory. The edge of the flat plate some burr, edges and corners are rounded, the corresponding fold some corner. When you install such a case, you don't worry about cuts, and some rough, poorly built cabinets tend to scratch your hands.

Q: How are the grades of high alumina bricks differentiated?: If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not exactly the sameFor example, European countries limit the content of Al2O3 for high alumina refractory materials at 42%.

Q: How to reduce the harm caused by two times mullite in high alumina refractory material: Prolong the sintering time and adjust the aluminum content of the high alumina brick.

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: High R.U.L, low creep high alumina brick [1] is using high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials. The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
