Q:What are the additives and recipes of refractory?
Add FDN.
Q:I know which material is the fire resistance rolling shutter door
Inorganic fiber cloth as curtain side replace steel fire shutter curtain of steel plate, the thickness of the inorganic fiber cloth is much thinner than the steel curtain plate and the density is very small, so the volume of the same area of ​​the inorganic fiber is super fire shutter the same area of ​​steel fire shutter half, and weighs only one more out of the same area a few steel fire shutter, however, the inorganic fiber super fire shutter fire but has a very good insulation properties. I hope my answers are helpful to you.
Q:How to choose the material of refractory?
Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
Q:What defect does fused cast refractories have ?
What defect doesfusion-cast refractory material have ? In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are sidewall block and brick kiln bottom. I hope my answer can help you.
Q:What material is used to make furnace pipe of refractory bricks?
Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be proceeded temporarily during cutting according to requirement.
Q:Which refractory is suitable for the tunnel kiln?
The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3.

Q:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ - 1770 ℃, advanced refractories: 1770 ℃ - 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler, (ratio) Max: Min < 4: 1; Shaped ones: no more than two-entrant, (ratio) Max: Min < 6: 1 or having a acute angle of 50 - 70 °; The specific type :( ratio) Max: Min < 8: 1 or having no more than 4-entrants or having an acute angle of 30 - 50 °; and Special products: crucible, containers and tubes. 3, divided according to the method of manufacturing: burned products, non-burned products and unshaped refractories 4. divided according to the chemical properties: acidic refractory materials, neutral refractory materials and basic refractory materials.
Q:How to hang the suspended brick in the refractory masonry?
First you can weld the metal fastener of the suspended brick and then hang up the brick.
Q:For refractory knowledge. What is the ratio of clay ramming mass?
Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
