Manufacturing good quality Silicon carbide
Product Description
Description:
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.
Chemical composition:

- Q:What things and cement mixed can act as refractory?
- Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
- Q:Why the corundum can be used as refractory
- It can resiatant to friction wear.The alumina material is a kind of neutral material with high temperature resistance, anti-acid, anti-corrosion, alkali resistance, and high hardness of corundum. The disadvantage is the poor thermal shock resistance, the main chemical composition of corundum is aluminium oxide and the melting point of corundum is 2080 degrees
- Q:Does anyone know about the fire resistance period of thin fireproof coatings?
- The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
- Q:How can refractory material of the electric furnace be used for longer.
- I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
- Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
- Q:What is refractory brick?
- Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
- Q:What antioxidant will be used in refractories?
- Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc
- Q:What effect does aluminium powder play in refractory bricks?
- Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.
