$High Aluminum Insulating Castable Refractory for High-temperature Industrial Kilns$

The main material of our high alumina insulating castable refractory is Al2O3—SiC—C,there’s 2 types including baking casting material and free baking material, the width of iron runner is required above 2.4 meter, the depth is above 1.7 meter, it has a good performance in site operation, with easy repair, tapping iron is allowed after pouring finished. Although the invest is more higher for once time, but it will be with a longer service life and a few mending work.

Q: How is grade of fire endurance divided?: Fire resisting shutter is divided into Class A / B / C, and the relevant fire endurance are not less than 1.2 /0.9 /0.6 hours, see "General technical conditions for steel fire resisting shutter GB 14102-93". 4.3 4.3.1 Classification according to time of fire resistance 4.3.1 Ordinary steel fire resisting shutter (see Table 3) Table 3 and Category Code Refractory time hF1 1.5F2 2.04.3.2 Composite steel fire resisting shutter (see Table 4). Table 4 and Category Code Refractory time hF3 2.5F4 3.04.4 Classification according to refractory time and smoke prevention performance 4.4.1 Ordinary steel fire and smoke resisting shutter (see Table 5) Table 5 category and code refractory time h smoke leakage (20Pa differential pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire and smoke resisting shutter (see table 6) table 6 category and code refractory time h smoke leakage (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min Excerpt completed. Fire shutter used as fire compartment has a fire resistance of 3 hours, and fire shutter set on the upper opening part on the firewall has a fire resistance of 1.2 hours. **** Materials with fire resistance of 3.0 hours are called AAA refractory material (back fire surface). "Building Conventions" have mentioned in places where it is really difficult to set a firewall, fire shutters can be used to separate fire compratment. When using fire shutters whose back surface temperature rise is included as the judging criteria of fire resistance, its fire resistance should be not less than 3.00h; When using fire shutters whose back surface temperature rise is not included as the judging criteria of fire resistance, independent protection of closed automatic water spraying system should be set on the both sides of the shutter, and the duration of water spray should be not less than 3.00h. In summary: Fire shutter is divided into: Grade AAA, A, B and C

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: I wanna ask about the building insulation materials fire rating?: Hello, I am happy to answer your questions about the classification of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you

Q: What is the difference between wear-resistant material and refractory material?: One is to require wear-resistance. It can be both fire-resistant and wear-resistant, and they can enter different categories. Faced with different demands, it has a variety of features. But both can also be integrated. I think many materials have same division. One is fire-resistant. The two concepts are different division. They are not comparable.

Q: Who can tell me about the foundry refractory materials?: The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming?mass, castable refractory, refractory cement, silica sand, magnesite, etc.

Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?: Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.

Q: Does refractory belong to stone, building materials or other?: Refractories belong to organic non-metallic materials.

Q: What are the characteristics of the carbon composite refractories?: The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag

Q: What are the differences between thermal?insulation?material and refractory?: Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
