Product Description:

97 Silicon Carbide90/Recrystallized Silicon Carbide/SIC

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

4.Refractory

Q:What are the characteristics of thealuminium oxide refractory?
Alumina refractory are characterized by uniform granularity, mobility, good dispersity. And it has good acid and alkaline slag erosion resistance, high strength, abrasion resistance, high melting point, erosion resistance , anti-flush and excellent thermal shock resistance.
Q:What are the fire endurance requirements of class A fire resistant door ?
Fire endurance of class A fire resistant door is 1.5h. According to the latest fire door requirements, in FMA FMB FMC three forms, A, B and C represent categories, such as FMA on behalf of Class A fire doors (ie thermal insulation fireproof door). Fire endurances of class A,B and C fire doors are 0.5 1.0 1.5 2.0 3.0. Therefore, the fire resistance of fire door needs to be designed and the design paper will make it clear in general.
Q:what should be paid sttention when buying the refractory?
solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4: 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
Q:Refractory materials are needed for casting metallurgy.
High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
Q:What is the main constituent of refractory brick?
There are several refractory bricks, including clay brick, carborundum brick and chromium-carbon. The type you said may be refractory bricks made from bauxite.
Q:What's the texture of refractory for the hearth of reverberatory furnace? ?
High alumina brick; you can use zircon brick under the temperature above 1700? ;may i use mullite bricks under the temperature from 1400 to 1700? you can use clay brick and heavy corundum brick under the temperature of below 1400 degrees, question closely: what's the usage temperature of reverberatory furnace? < pre accuse = "qRA" > is there someone use refractory fiber?
Q:Who knows about the fire endurance of grade C fire doors?
The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
Q:Which kind of refractory does insulation board belong to ?
Q:what is the grading standards of external wall thermal insulation materials?
external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:How is the fire endurance of the fireproof paint?
time is different according to the amount of fireproof paint used. fire resistance time :0.5 hours 1.5 hours 2.0 hours 2.5 hours thickness: 0.45mm 0.9 mm 1.4 mm 2.0 mm 2.8 mm Amount: 0.79kg / m2 1.5 kg / m2 2.3 kg / m2 3.3 kg / m2 4.6 kg / m2
