- Q: What's the texture of refractory for the hearth of reverberatory?furnace? ?
- The long-term usage temperature of ceramic fiber is between 950-1260 degrees.
- Q: What refractories are accessible with ease in daily life?
- Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic?refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay?bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks.

- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- Fire proof window of level B is the fire proof window whose duration of fire resistance is not less than 1 hour. Technical requirements: One, Materials and fittings (1) the frame of windows draw on steel or wood frames which have certain intensity and are able to ensure the integrity and stability of components. (2) Steel frame and layering can use galvanized steel or stainless steel plate. Its selection criteria shall be in line with provisions 5.1 of GB12955< steel fire door general technical conditions >. (4) The internal fillings of steel, wood frames should use non combustible materials. (5) Fire proof windows can opt for qualified products without affecting the performance of fire proof window. Light transmittance of glass shall not be less than 75% of the same layer of ordinary flat glass. (6)The sealing material between the frame and the fireproof glass should adopt the nonflammable materials, functioning as the fire blocker. (7)Hardware fittings should be tested for qualified products.
- Q: Which refractory quality inspection authority is good?
- National testing agencies include National Refractory Inspection Center (i.e. LIRR), China Building Materials Academy (Guanzhuang, Beijing), National Center for Ceramic and Refractory Materials Inspection (Shandong) and China Metallurgical Research Institute (Beijing).
- 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 main components of refractory cement?
- Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
- Q: What is refractory aggregate?
- It includes two categories: coarse aggregate and fine aggregate.
- Q: what is the specs of thermal insulation refractory slab ?
- thermal insulation refractory slab features wear proof, heat resistance, impact resistance, acid or alkali resistance, smoke resiatnce, fire proofing,fungi proofing, mould proof,anti-static. fireproof panel is generally used for countertops, tabletops, walls, cabinets, office furniture, wall hung cupboard. Common Specifications: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, thickness 0.6-1.2mm.
- Q: What are the grades of refractory exterior wall thermal insulation materials?
- Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
