Silicon Carbide Manufacture,Black and Green Silicon Carbide Powder


Black silicon carbide is quartz sand, petroleum coke in primary raw materials, smelting in the high temperature resistance furnace. Its hardness is between corundum and diamond; the mechanical strength is higher than alumina, brittle and sharp. It has a certain conductivity and thermal conductivity.

(1)   As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand tiles etc.

(2)   As the metallurgical deoxidizer and high temperature material.

Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials.

(3)   High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.

(4)   Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high temperature resistant to oxidation.

Usage:

1.The application in the non-ferrous metal smelting industry

Use silicon carbide’s high temperature, strength, good thermal conductivity and impact resistance, for high-temperature indirect heating materials, such as Jian Retort Furnace, distillation furnace trays, aluminum tanks, copper melting furnace linings, zinc furnace arc plate, thermocouple protection tubes.

2.The application in the iron and steel industry

Use silicon carbide’s corrosion-resistance, thermal shock resistance to abrasion and good thermal conductivity for increasing service life of large-scale blast furnace lining.

3.The application in the metallurgical ore processing

Silicon carbide with strong wear resistance, second only to the diamond hardness, is the ideal material for wear-resistant pipe, impeller, pump chamber, cyclone and ore bucket lined, also for the aviation runway. The wear resistance is 5-20 times of cast iron, rubber life.

4.The application in the building materials ceramic and grinding wheel industry

Use its characters of thermal conductivity, heat radiation and high temperature strength to make sheet kiln. It can not only reduce the kiln capacity, but also improve furnace installed capacity and product quality and shorten the production cycle. It is also the ideal indirect materials of sintering ceramic glazed baked.

5.The application in energy saving

Use its good thermal conductivity and thermal stability to make heat exchanger, saving 20% fuel consumption and 35% fuel and improving the productivity by 20-30%. In particular, mine processing plant with a discharge pipeline in place, the abrasion resistant material is 6-7 times mo re than common.

Q: What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q: Which brand of thermal insulating refractory is good?
The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃
Q: What a blast furnace refractories generally?
Common refractories often use silica?brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
Q: Which are fire proofing thermal insulation materials?
Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. In addition, there are also auxiliary products such as fire proofing cement gum, high temperature binder.
Q: What is the material composition of the new fire-resistant coating?
The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
Q: How to choose refractory material
The crystalline refractory fiber mainly consists of polycrystalline mullite fiber, the optimum use temperature is 1300 DEG C, and the long-term use temperature of polycrystalline alumina fiber is 1400 DEG C. The service temperature of ordinary refractory fiber is 1150 degrees, and the use temperature of advanced refractory fibers (such as alumina, zirconia, refractory fiber) can reach 1700 degrees centigrade
Q: Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q: Who know about the knowledge of acid refractory material? Please explain in detail.
Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.
Q: What's the material of fireproof and wear-resisting floor?
It is the kind of special concrete floor, and it should prevent from crash for it will produce fire by friction. It is mostly used for the warehouses storing explosive and inflammable objects and chemical materials. And its production process is the same with that of the common concrete floor, but it uses different material which needs to be the pebbles and sand after processing with marbles and dolomite.
Q: what's the detailed address of fireproof and thermal inuslation matertial market?
following are the detailed address of fireproof and thermal inuslation matertial market: Central China Building decoration materials market,Hanxi 1 road No 95, Xinyongan Tangcai decoration material makert, Jianghan district Tangcai road No 53, Baoye decoration material wholesale market, Wuhan Wuchang district Minzhu road No 620.
