Refractory High Alumina Brick for Hot Blast Furnace

 

Q: What kind of fused corundum corundum brick should be used for each part of the glass furnace?
In addition to AZS33# and AZS same co crystallization in vitro, 36#AZS due to the increase of chain like zirconia brick more crystals, while the glass phase content is low, so 36# AZS corrosion resistance has been further enhanced, so is suitable for the rapid flow of molten glass or high temperature region.AZS36 s is an excellent product in the AZS series. It has high resistance to glass liquid erosion and low pollution. It is usually used in the key parts of the glass furnace, such as the pool wall near the hot spot.
Q: How much is a thermal brick?
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q: Wave tile and throwing glaze, tile which good?
The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
Q: Expansion ratio of lightweight corundum refractory bricks
Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.
Q: How to improve the induction furnace campaign, from the promotion of refractory life start
Select suitable insulation materials, such as polycrystalline facing blocks and ceramic fiber modules, depending on the service temperature
Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
Q: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
Q: Is liquid phosphoric acid two aluminum hydrogen flammable?
Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.
Q: Ask for help about the phase of refractory material
Secondary crystalline phase. The second phase and second phase or second phase, and the main crystal phase and is in high temperature liquid phase coexistence in refractory material, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase. There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.
Q: What can zirconium sponge do for those industries?
Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
