Q:What's the poured refractory material?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:What dose the fireproof and thermal insulation material include?
It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:what's the standard of fireproofing material?
Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.
Q:Are refractory materials and fireproofing materials the same?
Refractory materials is flammable when it is reached certain temperature for a certain time, but it will not support burning when there is no open fire (such as: gypsum board). Fireproofing material reaches A grade and it is non-combustible itself.
Q:What are the main materials in concrete fireproofing material?
fireproofing materials mainly consist of class A incombustible material and class B1 nonflammable material. Class A incombustible material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.
