- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: How is the division of the fire resistant level of the rock wool board?
- It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible?building?materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible?materials. The incombustible?material refers to that when meeting the Oxygen in the air, it will not burn.
- Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
- I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
- Q: how to divided the external wall thermal insulation materials fire rating
- Level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high.
- Q: What refractories are used in various parts of the blast furnace.
- Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
- Q: Why do magnesium oxide refractory bricks can be made into refractories?
- Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.
- Q: Refractories for iron-making blast furnace?
- Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.
- Q: What is the limit of fireproof rolling shutter?
- Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
- Q: Is it normal for caable fire resistant material to catch on fire?
- Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
- Q: What kinds of refractory materials that can resist 3,000 Celsius degree?
- steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
