Application of white fused alumina
Made of abrasive, suitable for grinding hardened alloy steel, high speed steel. Fine-grained flour is also used for precision casting.
- Q:What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q:What's the requirements of fire-fighting criteria of heat insulating material?
- Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
- Q:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
- Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
- Q:Which brand of thermal insulating refractory is good?
- The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃
- Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
- Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
- Q:who knows the fire endurance of fireproof coating?
- It's fire endurance is 3hours. Fire endurance test of certain building components showed by standard time temperature curve from the starting of fire to lose of supporting capabilities or its integrity or fireproof property. unit time is one hour.
- Q:How many kilns using refractories are needed? What are the furnaces respectively?
- Rotary kiln, general alumina bricks, high alumina bricks, corundum - mullite brick and vertical kiln. I am limited. Please forgive me that I can only talk about what I know. There are tunnel kiln, clay brick, etc. which can be used in these kiln and shuttle kiln and so on. Shuttle kiln.
- Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- glass
- Q:I wanna ask that magnesium oxide is refractory?
- Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you
