refractory grade size 1-3mm calcined bauxite

1. Calcined Bauxite 1-3mm brief introduction:

Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated

aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).

Q:Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint. Galvanized surface generally is not necessarily needed for brushing fireproof coating. Fireproof and galvanized surface have relatively poor bond strength, so it is advisable to brush transitional lacquer or micaceous iron on the galvanized surface.

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:On the problem of making refractory materials: But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!

Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?: the fire endurance of fire window is: class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, Class C window is not less than 0.6 hour. technical requirements: 1, materials and accessories (1) the window frame is made by a certain strength of steel frame or wooden frame which is sufficient to safeguard the integrity and stability. (2) steel frame and mound layer can select galvanized?steel?sheet or stainless steel plate. Its selection standards should be in line with the provisions of Article 5.1. in GB12955 "Steel Fireproof Door General Technical Condition" (3) the selection standards of wood frame and mound layer should be consistent with the provisions of Article 5.1.1. in GB14101 "General Technical Conditions of Wooden Fireproof Door" (4 ) the inner filling material of steel and wood frame should be non-combustible material. (5) fireproofing glass can choose the qualified products in fire resistance test and not affecting the fire windows. light transmittance of glass is not less than 75% of identical layers of ordinary plate glass. ( 6) a sealing material between the frame and the fireproofing glass should use the nonflammable material, it can play the role of fireproofing and smoke insulation in the fire disaster. I hope I can help you

Q:What is the difference between wear-resistant material and refractory material?: Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.

Q:What high-molecular polymers can be used as fire-resistant material binder?: Organic silicon

Q:Can anyone tell me what is a high alumina refractory?: High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary?kiln and other thermal equipment.

Q:How to make fire resistant materials for building stoves: Grand Theft Auto Vice City plus life code is what?

Q:What is the acceptance standard of refractory?: It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.

Q:What are the characteristics of clay refractory materials?: Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
