Product Introduction:
Due to chemical stability, high thermal conductivity, low thermal expansion coefficient, good wear resistance, in addition to abrasive use, Silicon carbide can be used in many ways,
1) As abrasive, can be used for abrasive tools, such as grinding wheel, oilstone, grinding, sand tile etc.
2) As deoxidizer and high temperature resistant material.
3) Silicon carbide powder coating on the inner wall of turbine impeller or the cylinder body, to improve and extend the service life of 1 ~ 2 times for its wear resistance;
4) As the single crystal of high purity, can be used for manufacturing semiconductor, silicon carbide fiber.
5) Advanced refractory material, made from which, has thermal shock resistance, small volume, light weight and high strength, and good energy saving effect.
6) Low grade silicon carbide (SiC 85%) is an excellent deoxidizing agent, which can be used to speed up the steel-making, and easy to control the chemical composition, improving the quality of the steel.
7) Silicon carbide is also used extensively for production of silicon carbide heating elements.
Application
1. Grinding wheels
2. Heating elements
3. Coated tools
4. Refractory
5. Polishing ,Lapping
6. Ceramic
- Q:What's the difference between refractory metal raceway and fireproof raceway?
- Fire protection slot won't cause fire accident under the temperature of no more than 200℃. While the refractory cable tray is made with refractory materials and can withstand high temperature of 800℃ with no fire accident happening. The test standard depends on the maximum temperature it can endure. Hope it's helpful for you!
- Q:How many kinds of fireproof materials are there in the market?
- Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam material is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.
- Q:What's meaning of CN of fire-resistant material?
- The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
- Q:What are the characteristics of the carbon composite refractories?
- The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
- Q:Why the corundum can be used as refractory
- Corundum has high refractoriness, so its high temperature performance is very good.
- Q:What's the fire endurance of fire windows?
- Fire endurance of fire windows: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke control in the case of fire. (7) Hardware fittings should be approved supporting products which is detection qualified.
- Q:Can the teflon material resist fire?
- It is belonged to the fire retardant materials. By UL-V0 grade
- Q:How many hours of the fire endurance time of the rock wool laminboard?
- Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
- Q:What is the particle size of boron carbide for refractories?
- Ask, in the electric furnace magnesia carbon brick, boron carbide amount how many? Thank you The service temperature is around 1600.
- Q:What kind of material is refractory bauxite?
- Bauxite (aluminous soil; bauxite), also known as alumina or bauxite ore whose main component is alumina oxde, is a hydrated alumina containing impurities. It is an earthy mineral. It is white or gray, and as it contains iron, it is also brownish yellow or light red. Density of 2.4-2.5g / cm3, hardness 1-3, opaque and crispy. It is extremely difficult to melt.
