Q:whether the aluminum silicate thermal insulation material is fireproof or not?
Yes, it is fireproof. Refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and composite thermal insulation materials. According to the shape it can be divided into: Fibrous finishing, mineral cotton, rock wool, glass wool, aluminum silicate wool, ceramic fiber,ect.. it takes the flint clay clinker as raw material, produced by the fusion of resistance or electric arc furnace and the injection of fiber forming. characteristic: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
Q:I wanna ask about the thermal insulation material fire resistant level?
The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
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:Which brand of AAA refractory is good?
Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.
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:What are the applications of refractory busway?
Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, ther bus lines can operate full-load in long term.
Q:What is the function of refractory in ceramics?
It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.
Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:How to divide the fire rating standards of insulation materials?
1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. 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: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
