Specail Shape of High Alumina Brick
- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.
- Q: In 2016, a few of the traditional refractory materials will be able to survive
- From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: What is the content of free silica in the refractory bricks of high alumina bricks?
- Refractory powders are not rich in free silica in varying degrees
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q: The difference between ordinary and diatomite brick refractory brick
- Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
- Q: What is the difference between metal compounds and metal solid solutions?
- Sigma phase belongs to Affirmative system, there are 30 atoms in the unit cell, two element alloy, sigma phase formation is related with the following conditions: (1) the atomic size difference, phase difference between the maximum sigma atomic radius of a tungsten cobalt, the atomic radius difference is 12%. (2) there is a set of cubic lattice elements (coordination number 8), and another component is face centered cubic or dense six square lattice (coordination number is 12). (3) appear in "average number of races" (s+d layer electron number) in the range of 5.7 ~ 7.5. The region of the presence of sigma in the two - element alloy is shown in table 3. In the three element system, the concentration and temperature range of the formation of the sigma phase are affected by the addition of third components. Usually in chromium stainless steel in Fe Cr phase, in Fe - Cr - Mn three yuan, sigma phase iron chromium and chromium can form Mn two element, when the addition of manganese in stainless steel, will promote the formation of sigma phase, and stabilizes the wide temperature range. Many of the Fe Cr alloy elements. The phase temperature range increases. In less than 820C stable Fe Cr phase, silicon promotes the formation of D phase and the stable temperature increased to 900 to 960 DEG C, manganese and molybdenum can improve the temperature stability of sigma phase to 1000 DEG C.
- Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
