- Q: Application characteristics of high alumina brick
- Load softening temperature. The softening temperature of high alumina brick products decreases with the increase of silica and alkali metal oxide content, but is higher than that of clay brick products, which is about 1420 - 1530 degrees centigrade. Al2O3. The softening temperature of corundum brick with content greater than 95% can reach above 1600 DEG C.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: Density of high alumina bricks
- The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick
- 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: 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 distinguish the good or bad of the high aluminum brick?
- In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.
- 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: Which thermal shock stability of clay brick and high alumina brick is good?
- 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.Thermal shock stability is much better than clay brick.
