Grinding Black Silicon Carbide

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze,aluminum, stone, leather, rubber, etc.

Black Silicon Carbide with High Purity SiC made in China

Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.

Q: How long is the duration of fire resistance of hollow glass magnesium board: Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.

Q: What materials are needed to make the amorphous refractory bricks?: Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.

Q: Who knows about the grade C fireproof door materials?: Wood or steel materials are usually used in them. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively.

Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?: there are different temperatures in various parts of the blast furnace, thus using different types of refractory.

Q: What refractory material does cupola lining use?: In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.

Q: What is the definition and classification of amorphous fire resistance materials?: 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture

Q: Can refractory be used as sealing element?: It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.

Q: Who knows the roofing fireproofing and waterproof material?: Colorful glass?fiber asphalt shingles the roofing through special materials treatment just like wearing a waterproof, fireproof coat, water rolling down from the roof is similar to the effect of lotus leaf drops, the wall will be always in the dry state, having excellent waterproof, mould proof, efflorescence and weathering. It can prevent the growth of moss and keep the surface clean. And let your roof does not change color for a long time. Colorful fiberglass asphalt shingles materials are widely used in: All types of buildings roofing waterproofing, leak, fire, pollution, wind, and mould proof and moisture-proof of libraries and archives. The color retention of ancient architecture and protection of human cultural relics. Through the number of ten million square meters of engineering applications and two decades of practical test, it welcomed by users.
