- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: Application characteristics of high alumina brick
- Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.
- Q: What are the common thermal insulation materials for thermal conductivity?
- The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
- Q: What's the price of high alumina refractory bricks?
- The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
- 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: 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 the characteristics of high alumina bricks?
- High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
- 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: What are the specifications for bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q: Are there any differences between insulating bricks and refractory bricks?
- The refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. density insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
