- Q: What is fireproof concrete?
- Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.
- Q: What are the high aluminum bricks made of?
- We specialize in the production of various LeiBao refractory refractory material, such as corundum, zirconia products, alumina hollow ball products, mullite products and so on.
- Q: What is the price of the first grade high alumina brick?
- Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
- 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: What are the characteristics of high alumina bricks?
- 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 high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
- Q: How to reduce porosity of high alumina brick
- In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.The water absorption rate of the first grade high alumina bauxite clinker should be less than 5%, and the water absorption rate of two grade high alumina material should be less than 7%. Fine grinding of soft clay and bauxite clinker with less than 4% water content. Mixed fine milling ingredients with this, can reduce the porosity of bricks.
- Q: What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Sulphide. A total of more than 200~300 kinds, followed by the type of silicate minerals, the weight of 0.25% of the crust. Chang Fu is an important nonferrous metal deposit, which is an important source of copper, lead, zinc, antimony and so on. It is of great economic value. The main features are: metal luster, color, streak is deep, low hardness, good thermal conductivity, than the major. Another feature is that because sulfides are often associated with magma, it is very easy to oxidize under the surface supergene action. Except for pyrite (6 ~ 6.5 hardness), the hardness is very low. Such minerals pyrite, chalcopyrite, galena, FeS2 CuFeS2, PbS, Sb2S3, stibnite sphalerite molybdenite, cinnabar HgS MoS2.
- Q: The difference between ordinary and diatomite brick refractory brick
- To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- 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.
