Certification: ISO9001-14001
Minimum Order Quantity: 5 MT
Magnesite Brick
Description:
The main crystal phase of magnesite bricks is cristobalite, which has the typical characteristics of general alkaline refractory products, but the thermal shock resistance is poor. Magnesite bricks are divided into fired magnesite bricks and non-fired magnesite bricks. The fired magnesite bricks are divided into silicate-combined magnesite bricks, directly combined magnesite bricks and recombined magnesite bricks. Unburned magnesite bricks are divided into chemically combined magnesite bricks and asphalt combined magnesite bricks.
Advantage:
High thermal conductivity, strong resistance to alkaline slag, high refractoriness
Application:
Glass furnace regenerative chamber, heating furnace, soaking furnace, steel ladle
