Specification
Key Features
Refractory bricks are characterized by their ease of installation, thermal insulation, heat resistance, wear resistance, and chemical erosion resistance. They protect the
furnace
shell and are ideal for use in various industrial high-temperature kilns.
High compressive strength
Strong erosion resistance and stable volume at high temperatures.
High load softening temperature
Good thermal conducti
vity, high
fire resistance and load softening point.
High quality raw materials
Using excellent raw materials, it has good wear resistance at high temperatures and a long service life.
Processing customization
We can provide customized one-stop production and processing services according to customer requirements.
Good slag resistance
Magnesia bricks are alkaline refractory materials with periclase as the main crystal phase and high melting point second solid phase as the main bonding phase, and less glass phase.
Applicable to multiple ranges
Mainly used for steelmaking alkaline open hearth, electric furnace bottom and furnace wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, etc.
Applications
Glass Industry
The brick are used in glass melting furnaces and regenerators.
Petrochemical Industry
The brick are utilized in kilns and furnaces for ceramic production.
Steel Industry
The brick is extensively used to line the steel ladles, blast furnaces, and other high-temperature equipment.
Ceramic Industry
The brick is used in petrochemical processes, such as the construction of cracking furnaces and reformers.
Cement Industry
The brick are used in cement kilns and other cement production equipment.
Power Station Industry
The brick is used in boilers, incinerators, and other high-temperature equipment in power plants.
