1700C silicon carbide SiC bond Si3N4 tube
Silicon Nitride (Si3N4) bonded silicon carbide (SiC) material is a new type of advanced refractory materials. Compared with silicon carbide product, the product has characteristics of small thermal expansion, high thermal conductivity, not easy to have thermal stress, good thermal shock resistance, corrosion resistance, extreme cold or heat, oxidation, high temperature creep resistant ability and easily made into products with high dimensional accuracy requirements in line. Silicon nitride combined silicon carbide products have very high strength for normal atmospheric temperature, and it remains almost the same time with the strength and hardness at high temperature 1200-1400C. with the difference of using atmosphere, the maximum safe operating temperature could reach 1650-1750C.

- Q:What's the poured refractory material?
- Frequently used poured refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia.
- Q:What things and cement mixed can act as refractory?
- Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
- Q:Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q:What are the refractories for converter?
- Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
- Q:What is the definition and classification of amorphous fire resistance materials?
- 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
- Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
- 1. During the use of high- temperature refractory mortar, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
- Q:what is the original materials of fireproof coating?
- Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required. Some solvent-based fire retardant coating can burn upon encountering fire before construction.In fact,It is the flammable solvent contained in the coating that is burning while substances such as the base materials and fire retardant agent does not burn. Because solvent-based fireproof coating contains organic solvent and these fire-resistant coating, once leaked from the bucket, are likely to cause a fire. Fireproof coating on the substrate can insulate heat only after the solvent contained evaporates compeletly.
- 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 is the role of adding chromium oxide green in unshaped refractory materials
- Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
- Q:which kind of material is chosen for fireproofing window?
- Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
