Product Description

Low Porosity Clay Brick

This product is mainly used in glass heating chamber with features of low porosity, strong corrosion resistance, etc. To meet different environmental need of glass kiln, it is made in three serials according to corresponding process formulas: DN-a, DN-b, DN-c.

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 are the grades of high alumina bricks?: According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.

Q: What's the price of high alumina refractory bricks?: Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.

Q: Corundum, high alumina and fireclay refractory difference is what: In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..

Q: What are the specifications for bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

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: 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: Use of high alumina refractory bricks?: High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The rotary kiln lining structure of rotary kiln and requirements on refractories calcining active lime according to the general output is divided into Nissan 300t, 400 t, 600 t, 800 t, 1000 t, 12000 t of kiln type, calcining zone temperature at 1350 degrees celsius. The kiln is divided into a discharge end, a cooling zone, a burning zone, a preheating zone and a feeding end, and the temperature of each section of the kiln ranges from 1000 DEG C to 1350 DEG C, and the requirements for refractory materials are different. The kiln refractory materials not only to withstand the high temperature impact, but also need to bear the material erosion, kiln rotation stress produced, so not only on the physico-chemical properties of refractory materials have strict requirements, but also for the construction of brick should be strictly.
