product descriptionRefractory brick high alumina brick
High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is an ideal material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.

- 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 main components of high alumina bricks?
- High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- 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: What is the price of the first grade high alumina brick?
- The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories
- Q: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
- Q: What is the difference between high alumina brick and clay brick?
- Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: Is glass wool inorganic thermal insulation material?
- The characteristics of glass wool, glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
- 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: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
