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.


Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
Q:How does the physicochemical index change when the high alumina brick is used at high temperature?
When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
Q:In 2016, a few of the traditional refractory materials will be able to survive
In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
Q:What is spalling resistant high alumina brick?
Spalling resistant high alumina brick is a kind of high alumina brick. Antistripping high alumina brick with high grade bauxite and containing Zr02 synthesis as raw material, according to a certain proportion by high pressure molding system in sintering products, products with anti stripping ability, and have the anti erosion potassium, sodium, sulfur, chlorine and alkali salt, low thermal conductivity and other properties that is the transition zone of cement kiln and decomposition of ideal material with remarkable characteristics, the product is good thermal shock resistance, strong ability to adapt to the environment. It is used in the preheating or decomposing furnace, grate cooler and so on.
Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
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 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:What are the grades of high alumina bricks?
According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
Q:Can high alumina brick resist carburizing?
The resistance to carburization is not directly related to the bulk density of bricks
Q:What are the common thermal insulation materials for thermal conductivity?
The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
