Description of Kerui Silicon Carbide Bricks

Silicon carbide bricks are refractory bricks made by sintering silicon carbide and other fine powders at high temperatures.

• The addition of carbon monoxide can help improve the strength and wear resistance of the refractory bricks, while also helping to reduce costs.
• The addition of silicon dioxide can help improve the chemical corrosion resistance and thermal conductivity of the refractory bricks.

The combination of these two components gives the large refractory bricks excellent overall performance.

Types of Kerui SIC Bricks

Kerui SIC bricks are mainly divided by the following types. See their difference.Choose the suitable one.

Types	Features
Oxide Bond SiC Brick	High refractoriness: 1750ºC; High high-temperature strength; Good wear resistance; Good thermal shock resistance; Good corrosion resistance.
Green SiC Brick	High refractoriness: 1800ºC; High high-temperature strength; Good wear resistance; Good thermal conductivity; Good thermal shock resistance.
Corundum Silicon Carbide Brick	High refractoriness: 1900ºC; High high-temperature strength; Good wear resistance; Good corrosion resistance.
Mullite Silicon Carbide Brick	High refractoriness: 1750ºC; High high-temperature strength; Good wear resistance; Good thermal shock resistance; Good acid resistance.
High Alumina SiC Brick	High refractoriness: 1750ºC; High high-temperature strength; Good wear resistance; Good thermal shock resistance; Good alkali resistance.

Besides, this kind of brick is also can be divided by the difference in the bonding method:

• Oxide-bonded (clay-bonded, mullite-bonded, corundum-bonded);
• Nitride-bonded (si3N4-bonded silicon carbide bricks, sialon-bonded silicon carbide bricks);
• Self-bonded (β-SiC-bonded and recrystallized);
• Silicon-infiltrated reaction-bonded silicon carbide bricks.

Different Sizes of Silicon Carbide Blocks

Advantages of Silicon Carbide Refractory Blocks

• High-temperature Resistance: The melting point of silicon oxide can reach 2730 °C. The refractoriness of silicon carbide bricks is as high as 1900 °C.
• High Mechanical Strength: The Mohs hardness of Kerui silicon carbide bricks is 9. It is very hard. In addition, its flexural strength and compressive strength are 1.5-3 times that of ordinary refractory bricks.
• High Thermal Conductivity: The thermal conductivity of silicon carbide can be more than 10 times that of ordinary refractory bricks. It has good thermal conductivity. Silicon carbide has a high thermal emissivity.
• Low Thermal Expansion: The dimension of silicon carbide brick changes very little when the temperature rises.
• Good Wear Resistance: Silicon carbide brick has extremely high hardness, second only to diamond.
• Corrosion Resistance: The composition of silicon carbide bricks has a good anti-corrosion effect on chemicals such as acids, alkalis and salts.

Silicon Carbide Refractory Blocks Applied in Different Industries

• Steel and Non-ferrous Metal Smelting: They are used in non-ferrous metallurgical retorts (copper, aluminum, magnesium, lead, zinc, etc.), aluminum casting molds, electric furnace linings, aluminum electrolytic cell linings, blast furnaces, converters, open hearth furnaces, sintering furnaces, annealing furnaces, heating furnaces, ladles, tundishes, slag pots, etc.
• Industrial Applications: They are used in ceramic kiln furniture and heat exchangers, glass kilns, cement kilns, lime kilns, etc.
• Petrochemical Industry: They are commonly used in petroleum refining furnaces, reactors, pipelines, pumps, valves, etc.
• Power Industry: They are used in boilers, combustion chambers, desulfurization towers, dust collectors, chimneys, etc.
