- Q:Refractory factory grinding brick dust harmful to the body?
- Inhalation of this dust can affect people's respiratory tract for a long time
- Q:Physical and chemical indicators of various refractory.
- it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
- Q:What's the organzational structure of refractory material?
- Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition
- Q:Does the refractory material used in steelmaking all refer to refractory brick?
- It includes not only refractory brick but also unshaped refractory; while the foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
- Q:Can anyone tell me the requirements of the refractory masonry?？
- Kaolin is mainly composed of kaolinite crowded minerals that is in the shpe of tiny flake which is less than two microns, tube and folding flake. The kaolinite crowded mineral consists of kaolinite, dickite, pearl stone, halloysite, etc. and its ideal chemical formula is AL2O3-2SiO2-2H2O. The main mineral component of it is kaolinite and halloysite.In addition to the kaolinite crowded mineral, kaolin is accompanied by other minerals like montmorillonite, illite, pyrophyllite, quartz and feldspar. The chemical composition of kaolin contains large amounts of AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and traces of K2O, Na2O, CaO and MgO, etc. The white pottery is made of kaolin. At present, the internationally accepted scientific name for kaolin is Kaolin which is derived from the kaolin mountain in the eastern suburb of kaolin village in Jingdezhen.Such special properties of kaolin as its plasticity,cohesiveness, certain dry strength, sinterability and firing whiteness make it the main raw material for ceramic production; properties like whiteness, softness, high dispersibility, and adsorbability allows it to be widely used the paper industry. In addition, the kaolin is also widely used in some industrial sectors such as rubber, plastics, refractories, oil refining as well as agriculture sector and cutting-edge technology for national defense. According to the purpose and requirements, kaolin can be processed and purified and it can be used to manufacture activated clay.
- Q:What are the types of advanced refractory?
- it can be divided into two categories of general and special refractories ordinary refractories by chemical properties into acidic, neutral and alkaline. Special refractory composition divided by high temperature oxide, refractory compounds and high-temperature composite materials Furthermore, according to refractoriness can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and grade refractory products (2000 ℃ above). the article can be divided into blocks (standard bricks, shaped bricks, etc. ), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron quality, etc.) and a random shape (refractory clay, pouring materials and ramming mixes, etc.) according to the sintering process it can be divided into sintered products, cast products, melt blown products.
- Q:Which refractory is suitable for the tunnel kiln?
- Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
- Q:What are the fire endurance requirements of class A fire resistant door ?
- Fire endurance of class A fire resistant door is 1.5h. According to the latest fire door requirements, in FMA FMB FMC three forms, A, B and C represent categories, such as FMA on behalf of Class A fire doors (ie thermal insulation fireproof door). Fire endurances of class A,B and C fire doors are 0.5 1.0 1.5 2.0 3.0. Therefore, the fire resistance of fire door needs to be designed and the design paper will make it clear in general.
- Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
- Sodium silicate, pure calcium aluminate cement, boric acid
- Q:In entering fire door, which material does well?
- Cold rolled steel, or after a flame retardant willow eucalyptus wood, filled up with perlite inside! Fireproof heat insulation. Price is between 300-900, depending on what technology it uses! Company's large-area substrate door (paint) is cheap door, in commonly 350. Followed is without lacquer, which has a layer of decorative materials, generally between 380-500. Finally there is high-grade, which price is around $900. 0...
