Application field of silicon carbide:

First: refractory (silicon carbide powder, silicon carbide particles)

(1) silicon carbide specifications: the content of 97%, 95%, 88%-90%, 80%-85%, 70%-75%, 65-60% and other products, particle size is mainly 10mm-0, 5mm-0, 3mm-0, 1mm-0, 200#-0 and so on.

(2) the role of silicon carbide: silicon carbide as an inorganic non-metallic material, with high temperature resistance, wear resistance and other characteristics. Silicon carbide products combined with silicon nitride can be used in blast furnace ceramic cups and other places. Silicon carbide can also be added as an antioxidant in non-fired bricks such as ladle aluminum-magnesium-carbon bricks.

The refractory plate made of silicon carbide has high compressive strength and long service life. Low thermal capacity, low thermal conductivity; Non-brittle material, good toughness; Accurate size and good flatness; Easy to cut and install, easy to construct; Excellent resistance to wind erosion; Continuous production, uniform fiber distribution, stable performance; Excellent sound absorption and noise reduction performance.

Silicon carbide anhydrous gun mud has high fire resistance and strong resistance to scour of iron slag solution. Moderate plasticity; Good volume stability; Can quickly sintering well sintering strength; Good opening performance, opening machine drill is easy to drill and other advantages.

Second: abrasive, grinding, polishing, sandblasting, etc. (silicon carbide sand/silicon carbide particle size sand)

(1) silicon carbide specifications:

F sand series: F12, F 14, F 16, F 20, F 22, F 24, F30, F 36, F 40, F 46, F 50, F 60, F 70, F 80, F 90, F 100, F 120, F 150, F 180, F 220, F 240

P sand series: P12, p14, P16, P20, p24, P30, p36, p40, P50, P60, P80, p100, P120, P150, p180, p220.

Sand series of each section (mm) : 1-0,1-3,0.5-0,1-5,200-0,180-0, etc

Can be processed according to customer requirements for different granularity segment

(2) the role of silicon carbide:

Mainly used as abrasive for making grinding wheel, sandpaper, belt, whetstone, grinding block, grinding head, grinding paste.

The product has moderate hardness, high toughness, good self-sharpening, low sand consumption and can be recycled and used. And the chemical composition is stable, wear-resistant acid and alkali.

Silicon carbide can be used for manufacturing consolidated abrasive tools, coated abrasive tools and free grinding, so as to process glass, ceramics, stone, jade, cast iron, stainless steel, floor tiles and some non-ferrous metals, hard alloy, titanium alloy, high-speed steel tools and grinding wheels.

European standard :F280, F320, F400, F500, F600, F800, F1000, F1200, F1500, F1800

(2) the role of silicon carbide: silicon carbide powder is mainly used in the manufacture of refractory products, foam ceramics industry, solar silicon plate cutting, crystal cutting and grinding, automobile engine parts manufacturing, special coating industry, plastic products modification, desulphurization, power supply, environmental protection industry.

(3) picture of silicon carbide: silicon carbide powder

Fourth: steelmaking and casting industries: (silicon carbide ball, silicon carbide block, silicon carbide particle, silicon carbide powder)

(1) specification of silicon carbide: the content is 90%, 85%, 80%, 75%, 60%, 88-90, 80%-85%, 70%-75%, 65-60%, etc., the particle size is mainly between 0-100mm, among which 30-50mm is used more.

(2) the role of silicon carbide:

Silicon carbide, as a steel deoxidizer, can stabilize the quality of molten steel, refine grain and remove harmful impurities in molten steel. After use, the molten steel has high casting temperature, good casting quality and low unit cost.

Silicon carbide can completely replace ferrosilicon and carburizer, and the amount of FeALSi is also reduced, which can effectively reduce the cost of steel production by 6-10 yuan/ton.

Silicon carbide in high temperature decomposition and oxidation is the exothermic reaction process, positive pressure in the furnace is strong, can ensure that deoxygenation, sulfur provides the necessary conditions, reduce sulfur content.

Foamed slag is abundant and active in the application of silicon carbide. At the same time, the foamed slag covers arc yellow and reduces arc radiation, thus improving the life of furnace lining and furnace cover and reducing the time of hot shutdown and consumption of auxiliary materials.
