Product Description:

Silicon Carbide/SiC/Competitive Price of Silicon Carbide

1.Structure of CNBM'S 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 CNBM'S 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 CNBM'S 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:Does refractory belong to stone, building materials or other?
It belongs to building materials.
Q:What kind of refractory bricks material is best?
It depends on your purposes. In general, aluminous fireclay brick is usually used. GB/T 3994-2005 insulating fireclay brick. Bricks with good textile are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.
Q:Who know about the knowledge of acid refractory material? Please explain in detail.
Refers to the silicon dioxide
Q:How to use fire-resistant soil?
Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:What is the difference between the fire rating and the fire resistant level of the fire-fighting equipment?
Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
Q:What are the characteristics of clay refractory materials?
Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
Q:What are the additives and recipes of refractory?
Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).
Q:What is the particle size of boron carbide for refractories?
Ask, in the electric furnace magnesia carbon brick, boron carbide amount how many? Thank you The service temperature is around 1600.
Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
China is mainly used in honing, maybe I face all doubt you forget who may waste cheap no taste who cheated you don't mind set back easily stripped of a planet in the comfort of your brow you open your mouth and then grow the universe to my hand behind you let you spend what a fragile Oh maybe I face all abandoned about half past three in the morning wake up to drink a cup of soda rather baffling weary belch a bubble the tiny uneasy, and perhaps two of us Butterfly
