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 Silicon Carbide
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 Silicon Carbide
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 can red stone refractory do?
- Classification is divided into ordinary and special refractories two major categories. Ordinary refractories are divided into acidic, refractory, neutral and alkaline according to their chemical characteristics. According to the special refractory material consists of high temperature oxide, refractory compounds and high-temperature composite materials in addition, in accordance with the fire intensity can be divided into ordinary refractory products (1580 to 1770 DEG C), advanced refractory products (1770 to 2000 DEG C) and special refractory products (more than 2000 DEG C). According to the product shape can be divided into block (standard brick, special-shaped brick), special shape (crucible, sagger, pipes, etc.) (fibrous silicate aluminum, zirconium oxide and boron carbide material) and indefinite shape (refractory clay, pouring material and ramming material etc.). According to the sintering process, the products are divided into sintered products, casting products and fused blowing products. The main varieties of in general and special refractory materials, common varieties are mainly the following: acid refractories have a larger amount of silica brick and clay. Brick is siliceous products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste. The silica acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high, close to the fire, the volume does not shrink after repeated burning, or even a slight swelling, but poor thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Containing 30% ~ 46% alumina clay brick, with refractory clay as the main raw material, refractory 1580 degrees to 1770 degrees, good thermal shock resistance, which belongs to the weak acid refractory material, resistance to acid slag, widely used, is the largest production of a kind of refractory material.
- Q:How to divide fire resistant level of fire door?
- Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
- Q:What are fireproofing materials?
- Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .
- Q:What is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
- Q:What are the filling refractories in door leaf of class A fire resistant door?
- Perlite!
- Q:Physical and chemical indicators of various refractory.
- it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
- 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.
- 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: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:Is the ball mill used in production of refractories?
- It will be used. It is used in the process of milling the raw material which is less demanding on technology and in relatively large amount. Is there lots of network marketing for refractory industry? Is the competition fierce on the Internet?
