Magnesite brick

Magnesite bricks possess excellent thermal conductivity and specific heat capacity properties, and are resistant to alkali erosion. They are particularly suitable for working as checker bricks in glass furnace regenerative chamber.

Other name: Magnesia brick, Periclase brick

Model Number: HCR M91,HCR M93,HCR M95,HCR M97

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
