Manufacturing Good Quality Silicon Carbide


 

Silicon carbide is made of silica sand, coke, wood and other raw materials by resistance furnace smelting at high temperature. It hassteady chemical composition, anti-abrasion, anti-corrosion, high temperature resistance, good heat conduction and so on. Now SiC produced by China's industry can be divided into black SiC and green SiC. 

Use:

 

They are mainly used in four big application fields: functional ceramics,refractories, abrasives and metallurgical raw materials .

 SiC is suitable for cupola and electric furnace. 

As deoxidizer, it is widely used in foundry and steel industry. It can rapidly increase the temperature of molten steel, shorten smelting time, at the same time, it also can play deoxidizing, increasing carbon and silicon, heating up role. It can improve the quality of steel.

 

Characteristics:

1. Increasing carbon and silicon, reducing the consumption of 

carburant,ferrosilicon and other alloy, saving the cost of per ton steel.

2. AS SiC is oxidized, it can release a large number of heat energy,  reduce the cost of electric, lower the cost of production.

Q:Can the teflon material resist fire?
It is belonged to the fire retardant materials. By UL-V0 grade
Q:About the market issues of thermal insulation material and refractory material.
After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
Q:Which are fire proofing thermal insulation materials?
aluminum silicate fiber, ceramic fiber, etc,
Q:I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry! I hope you can help me! This time!
Stable chemical properties. The crucible material should not be hydrolyzed at low temperature. It is difficult to be decomposed and reduced at high temperature and is not susceptible to corrosion by molten slag and molten metal;
Q:Where is refractory used? Thank you!
Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
Q:What's the organzational structure of refractory material?
Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition
Q:What's the material of electrical fire prevention board?
Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
Q:What is the main constituent of refractory brick?
The main constituent of silica brick is monox, etc. Refractory bricks have many kinds of texture. The main constituent of high alumina brick and clay brick is aluminium oxide. The main constituent of every texture is different. The main constituent of magnesia bricks and magnesia-chrome bricks is magnesium oxide.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
Q:Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
