Q:About the market issues of thermal insulation material and refractory material.
After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?
For high efficiency continuous casting, molten steel will cause turbulence in tundish because of its fast casting speed. The sharp turbulence, on the one hand, breaks through the slag layer, involves the slag in the molten steel, and exposes the liquid steel to the air. It is oxidized two times;
Q:What is the the best matching ratio of refractory cement?
The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. 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. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. 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. It is a special cement. I hope my answer will be helpful to you.
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:Development trend of refractory industry
China announced that from 2004 January, the export of most refractory raw materials will be cancelled, and the export of finished products will also reduce the tax rebate rate. This means that important raw materials for further export restrictions, some developed countries dependent on imports of China's refractory materials and products of the refractories industry will have a major impact. In order to reduce costs, they will move their factories to Chinese, which is the development of Chinese refractories industry will also be an important opportunity. In addition, the convenience of communication and transportation, the change of the international market and the increase of e-commerce have also brought good opportunities to the development of refractory industry.
Q:Concrete composition and function of magnesia bond used in refractory
The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick
Q:Can you tell me the classification of fireproof sealing material.
Organic fireproof sealing material include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. Organic plugging material take organic materials as the adhesive with certain flexibility or plasticity when used. The product is thick liquid or cement. Inorganic plugging material take powder of solid inorganic material as the main ingredients, and admixture mixed use, with proper workability. Fireproof bag apply bag shaped object made up by fire-proof materia to large hole fire plug or cable tray fire compartmentation (fire package also called as refractory package or fire protection package). Fire modules is made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. fireproof sealing material is the plank made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. Foam block after injection holes can lathery foam and seal hole. Sealing strip is made of fire prevention materials with certain geometry shape or flexible coil geometry.
Q:Are refractory materials and fireproofing materials the same?
The refractory material and fireproofing material are not the same in the strict sense. Refractories refer to non-metallic materials of which refractoriness are higher than 1580 degrees. Now commonly used heat insulation materials can also be considered as refractory materials. The fire endurance of fireproof materials reaches certain requirements. Its test temperature is 540 degrees. Range of applications for two material are not the same. Refractory materials can be used in high-temperature region as it can withstand high temperature. Fireproof materials can not be used under high temperatures for a long time.
Q:Development trend of refractories
Mullite Matrix clinker. There are higher requirements of kaolin and refractory annded life, it should be able to grind medical industrial raw materials alumina, vacuum extrusion molding, high temperature roasting and smelting from unshaped refractory material a good thermal mechanical properties in the kiln and has good application prospect; 2, Dong Qingshi clinker. With kaolin and magnesia as raw materials, wet grinding, vacuum extrusion, and then high temperature calcination, furniture has a very good prospect; 3, magnesium calcium sand. Because of the development of clean steel, low carbon steel, high oxygen steel and stainless steel, the basic importance of free calcium oxide refractories is supported; 4, fused eutectic composite. Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite zirconia, fused corundum zirconia fused zirconia, Magnesium Oxide and other materials have been developing rapidly; 5, high density spherical hollow mullite aggregate. The wall thickness of the shell of the 0.2 - 1.5 - 5 mm, diameter 40 mm, smooth surface, can not be uniform, spherical shell, this may be a double, a prominent part of the surface can be dense, can also be used for hollow casting material, not only can improve the insulation performance of the material, in order to reduce the volume density. Instead of destroying its strength.
Q:What kind of refractory material should be used for common boiler?
Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
