Q:How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

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 light high alumina brick and heavy aluminum brick: High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.

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 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 much is the bending temperature aluminum silicon carbide brick for torpedo car: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.

Q:What are the requirements for Rubble backfill height?: 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

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 kind of material is the general metal case?: Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.

Q:What is the high temperature limit of refractory bricks and refractory soil?: Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
