Manufacture SiC/Black Silicon Carbide Powder for polishing quartz glass
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
2.Bonded abrasive tools, lapping and polishing
3.Widely used as a metallurgical additive and refractory material

- Q:How to divided the grade of external wall thermal insulation materials?
- 1, According to China's national standard GB8624-97, combustion performance of building materials will be divided into the following grade level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high. 2, The external wall thermal insulation materials is divided by fire rating 1) level A combustion performance thermal insulation material Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope my amswers are helpful to you

- Q:I wanna ask that magnesium oxide is refractory?
- Yes, Magnesia belongs to ionic crystals, the oin of magnesium has two charge, oxygen and magnesium ions are relatively small radius, these two factors make a lot of magnesium oxide lattice energy, high melting point is up to 2800 degrees Celsius. Because the magnesium oxide is stable and not react with water, it is widely used as a refractory material.
- Q:What are the requirements for the performance of refractory materials?
- Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.
- Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q:What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
- The rapid development of the technology of continuous casting refractories so the corresponding development and improvement in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
- Q:Refractories for iron-making blast furnace?
- Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.
