- 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 main components of high alumina bricks?
- Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.
- Q: Introduction of high alumina brick
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.
- Q: What is the difference between corundum and high alumina??
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q: What's the price of high alumina refractory bricks?
- Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.
- Q: What is the density of a super high alumina brick and what is the price?
- Of course, the transaction price, please choose refractory brick manufacturer is better.
- Q: How to reduce porosity of high alumina brick
- When proportioning, the ratio of coarse to medium to fine is 4:2:4, and the maximum particle size should be no more than 5mm. The mixing order is as follows: first adding coarse particles, then adding sulfite pulp waste liquid, premixed 3min, then adding high aluminum fine powder for mixing. The operation process is coarse and fine particles added in sulfuric acid with crushed pulp waste.In order to reduce the porosity, our company suggested that the single-sided pressure changed to double-sided pressure instead of double-sided pressure, the number of strikes should also vary according to the amount of feeding. If the kiln is fired, the location of the fire hole shall be adjusted so that the middle part is dense, the edge is thin, and the door near the kiln is properly encrypted so that the temperature difference between the furnace top and bottom and the temperature difference between the inside and outside are not greater than 20 degrees.
- Q: Which is better, the soft core or the hard core?
- The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.
- Q: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is 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: What is the apparent porosity of high alumina brick?
- Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
