Application of white fused alumina
1.Light-weight insulating refractories
2.Shaped and unshaped refractories
3.Pre-cast shapes and castables
4.High Alumina Refractory mixes and gunning mixes
- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: What is the main constituent of refractory brick?
- The main constituent of silica?brick is monox, etc. Refractory bricks have many kinds of texture. The main constituent of high alumina brick and clay brick is aluminium oxide. The main constituent of every texture is different. The main constituent of magnesia bricks and magnesia-chrome bricks is magnesium oxide.
- Q: How long can gypsum board endure fire?
- Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.
- Q: What's the fire?retardant material of roller shutter fire resistance door ?
- Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- Fire protection slot won't cause fire accident under the temperature of no more than 200℃. While the refractory cable tray is made with refractory materials and can withstand high temperature of 800℃ with no fire accident happening. The test standard depends on the maximum temperature it can endure. Hope it's helpful for you!
- Q: What is special refractories?
- Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
- Q: What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
- The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
- Q: What is the mechanism of the errosion of the iron to the refractories?
- For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
- Q: How long is the fire endurance of fire resistant rolling shutter door?
- According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
