Industrial Product Refractory Material With High Quality

Thanks for you interest in our products. We have been original factory and professional manufacturer for 18 years ,we have confidence to have your 100% satisfactory .Let us know if anything we can do for you .

White Aluminum Oxide:

White Aluminum Oxide is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.

Applications:

1. It is used as abrasives materials and in lapping processing.

2. It is also used in polishing and acrylic fabric of prettify processing.

3. Sandblasting in producing television screen.

4. It can be used in cutting silicon wafer.

5. Sandblasting in washing teeth model.

6. It could be the molding sand for precision casting.

Q: Who knows the refractoriness of high temperature lightweight firebricks?: Hefei Jiu oak decor help you answer; the biggest feature is refractory: refractoriness 700.

Q: Kinds of refractory mortar: It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.

Q: Who knows the classifications of magnesia refractory?: They can be devided into two major categories of fettling magnesite grain and magnesite products. They can be divided into fettling magnesite grain, magnesia?brick, magnesia-silica brick, magnesia-alumina brick, magnesium-calcium brick, magnesia-carbon brick and other varieties according to the chemical compositions and purposes Its performance is greatly affected by CaO / SiO2 ratio and impurities. The load softening point and thermal shock resistance of high purity magnesia brick are much higher than those of the general magnesia bricks. It has high refractoriness and good resistance for alkaline slag and iron slag, which is an important kind of advanced refractory material. Magnesia products are mainly produced by sintering, and sintering temperature is generally between 1500 ~ 1800 ℃. Besides, chemical binder can be added to make unburned?bricks and unshaped refractories. Mainly used in open hearth furnace, electric furnace, oxidation converter, non-ferrous metal metallurgy furnace, cement kiln and calcining kiln for basic refractory.

Q: What's the difference between refractory metal raceway and fireproof raceway?: Refractory metal is used to lay and control cables, while trunking is used to lay wires and communication cables; refractory metal is bigger (200*100-600*200), while trunking is smaller; refractory metal has bigger turning radius, while trunking mostly turns a right angle; refractory metal has larger span, while trunking has smaller span; their fixation and installation ways are also different.

Q: How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?

Q: What are the filling refractories in door leaf of class A fire resistant door?: Magnesium chloride, magnesium oxide, perlite and other mixtures.

Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!: High enough for high temperature resistance. Refractory materials for crucibles shall be subjected to a high temperature greater than 1700 DEG C and the softening temperature shall be greater than 1650 DEG c;

Q: what is the material of fixed first rate fire resistant window?: Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.

Q: How many kilns using refractories are needed? What are the furnaces respectively?: There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary?kiln (silmo brick

Q: How many levels are there in the classification of PP fireproof materials?: The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials are highly flammable with no flame retardant ability, fire risk is high.
