High hardness:
The Mohs hardness of silicon carbide bricks is 9, second only to diamond and boron nitride, and is a high-hardness ceramic material.
High hardness gives it excellent wear resistance and can maintain good performance in harsh working environments.
High temperature resistance:
Silicon carbide bricks can withstand temperatures up to 2700°C, which is superior to most ceramic materials.
It can maintain stable physical and chemical properties in high temperature environments and is suitable for high temperature applications.
High thermal conductivity:
It has good thermal conductivity, which is particularly important for industrial equipment that requires efficient heat transfer.
Low thermal expansion coefficient:
It is dimensional stable at high temperatures and is not easily deformed or cracked due to temperature changes.
Thermal shock resistance:
It can withstand rapid temperature changes without cracking or breaking.
High strength:
It can still maintain high strength at high temperature, with high compressive and flexural strength.
Corrosion resistance:
It has high stability in corrosive media such as acids and alkalis, and prolongs its service life.
Uses of silicon carbide wear-resistant bricks:
Metallurgical industry:
Used for metallurgical steel cylinder lining, nozzles, plugs, blast furnace bottom and belly.
Silicon carbide bricks are also used in non-ferrous metal smelting distiller, distillation tower tray, electrolytic cell side wall, etc.
Chemical industry:
Used in oil and gas generators and organic waste combustion furnaces in the chemical industry, it can effectively resist corrosion and erosion and has a long service life.
Other industries:
Silicon carbide bricks are also used in the shelf and flame insulation materials of silicate industrial kilns, aluminum electrolytic cell linings, molten aluminum conduits and ceramic kiln kiln furniture.
Due to its excellent wear resistance and heat resistance, it is also used to make key parts such as water-free cooling slide rails of heating furnaces, the lower part of the furnace body of large and medium-sized blast furnaces, furnace waist and furnace belly.
