1.Structure of Silicon Carbide Description
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.
Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.
2.Main Features of the Calcined Bauxite
Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.
3.Main usage of the Calcined Bauxite
1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

- Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
- Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: Where is the distributing center of refractory materials in China?
- The infrastructure is perfect, service and refractory chemical industry professional market ancillary services, information, transportation, food, housing, and other one-stop perfection. The business service center, Yongan business city, Fukang company, Xu Bai Anlong logistics center and the market has been basically formed, the market in more than 200 dressing rooms at the end of September put into use, logistics center, warehouse industry nearly twenty thousand square meters can use for customers. The Fasthotel, the dormitory and the information center will be ready for delivery, and large transport teams will be built to provide accommodation, freight and other convenient services for the owners.
- Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?
- 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
- Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?
- fused cast bricks, fused zirconia corundum blocks, corundum, high zirconium
- Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
- I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
- Q: what's the fire endurance of fireproof?panel?
- fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
- Q: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: What's the frequently used refractory material?
- What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica?brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing?mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc. Special Refractory: 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, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation?board, etc.
- Q: What 's the highest temperature can magnesium plate glass resist ?
- You just need a fire-resistance board thicker than 10 mm ,remember to add more perlite as filler during production , 12 mm plate is 80 yuan.
- 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
