Product Description:

SIC >98% F10-F1600 black silicon carbide for refractory&abrasives

 

Product Description

 

Black Silicon Carbide is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke.

The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.

Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity.

Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important .

 

 

Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree.

Aplications :
Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing.

The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc.

Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q:What are the electrical fire protection materials?
Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help 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 materials 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:Does anyone know the characteristics of refractory for glass kiln?
Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
Q:What are the applications of refractory busway?
Fire-resisting busway can be applied to power transmission and distribution systems with rated voltage below 690V, rated current is 250-5000A and frequency is 50-60Hz. After years of testing and industrial electrical operation, its electrical resistance, fire resistance, metal structural property have reached the advanced level in China.
Q:What's the fire resistance test method of doors and roller shutters?
Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
Fire endurance (h): Under the condition of standard fire resistance test, the time when the building components, accessories, or structure is subjected to fire to the time when they loose stability, integrality or thermal insulation is called fire endurance which is showed in time. Steel is the kind of building material that is nonflammable with many properties of seismic resistance and bending resistance. In practical applications, steel can improve the load capacity of buildings in a relative way, meet the needs of buildings design, beauty and mould, and it can also avoid the defects of poor flexibility and tensile strength of buliding materials like concrete. Therefore, steel is quite popular in the construction industry, and it is widely used in single-story or multi-storey skyscrapers, plants, warehouses, waiting rooms and airport terminals, etc. However, as a kind of building material, it has some unavoidable defects in fire prevention. That is its mechanical properties like yield point, tensil strength and elasticity modulus will decrease dramatically with the rise of the temperature.
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
who knows the classification of fireproofing glasses, how long is the fire-resistant time?
Q:What are the models of bauxite with high alumina?
China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.
