Magnesite Bricks

There are two types of Magnesite bricks:

Burned Magnesite Brick

  • Material and Technique: magnesia as raw material
  • Property: good high-temperature performance, strong slag resistance
  • Application: used in permanent linings of EAF and steel Convertors, lime kilns, glass tank regenerators, torpedo cars and non-ferrous furnaces
  • Fused Magnesite Brick

  • Material and Technique: fused magnesia, shaped under high pressure, fired under ultra high temperature and finished with post technical treatment
  • Property: high bulk density, good high-temperature performance and strong hydration resistance
  • Application: used in the tapping hole of the convertor with severe slag corrosion and wear, the slag line of non-ferrous furnaces, the tapping hole of metal mixer furnaces, and chimney block of glass tank regenerator
  • Magnesite Alumina Brick

    There are two types of Magnesite Alumina Bricks

    Magnesite Alumina Brick

  • Material and Technique: made from high quality magnesia and alumina bauxite with phase of periclase and spinel
  • Property: good high-temperature performance, high thermal shock resistance, strong slag resistance and high RUL performance
  • Application: used in steel ladle, permanent lining of steel furnace, iron mixer and other refractory material industry furnaces
  • Magnesite-Alumina Spinel brick

    Magnesite-Alumina Spinel Brick is our newly developed environmental friendly product with high quality performance for the cement kiln and glass kiln markets. It has won huge success in both domestic and oversea markets.
  • Material and Technique: made from high purity magnesia and synthetic magnesite-alumina spinel clinker with major phase of periclase and spinel.
  • Property: good high temperature performance, high thermal resistance, strong slag resistance
  • Application: used in the transition zone in cement rotary kilns, glass tank regenerators, lime kiln and the refractory material zones where experiences great temperature change.
  • Magnesite Chrome Brick

    Magnesite Chrome Bricks is one of the major refractory products. There are three types:

    Ordinary Magnesite Chrome Brick

  • Material and Technique: made from sintered magnesia and chrome ore and sintered at high temperature
  • Property: having higher bulk density and stronger thermal resistance than the magnesite brick
  • Application: used in cement rotary kilns, glass kiln regenerators, permanent lining of steel furnace permanent and refining ladle permanent lining of refining ladle.

    Directe-Bonded Magnesite Chrome Brick

  • Material and Technique: made of low impurity chrome ore and high purity magnesia and fired at high temperature over 1700?
  • Property: strong slag resistance and good performance under high temperature
  • Applied in cement rotary kilns, electric arc furnaces, and non-ferrous metal furnaces

    Rebonded Magnesite-Chrome Brick and Semi-Rebonded Magnesite-Chrome Brick

  • Material and Technique: made with synthetic fused magnesia, shaped under high pressure and fired at ultra high temperature
  • Property: Thanks to the high purity of the raw material, the product has good high temperature performance, high thermal resistance, low air-permeability, and strong slag resistance
  • Application: used in tapping hole of AOD furnace, the lower vessel of vacuum chamber and snorkel of RH furnace, and the slag line of high temperature furnaces

    The Semi-Reboned Magnesia-Chrome Brick is made from Fused Magnesia-Chrome melting grain, high purity fused and burned magnesia sands, and chrome ore through ultra high temperature. It has both the excellent thermal shock resistance of the direct bonded brick and the good corrosion resistance of the Fused Rebonded Magnesia-Chrome Bricks.

    The Semi-Reboned Magnesia-Chrome Brick is a rebonded product made from the fused grain of the fused magnesia-chrome.

    Magnesite Dolomite Brick

    We proudly represent Magnesite Dolomite Brick - our Magnesite Dolomite Brick is the most advanced level in the refractory industry in China and we have become the major supplier of the world wide.

    Magnesite Dolomite Brick

  • Material and Technique: Magnesite Dolomite brick is made from high purity and density magnesia and sintered magnesia dolomite clinker with major components of periclase and lime. The brick is shaped under high pressure and fired with high temperature, with appropriate MgO/CaO ratio raw materials to meet with the requirement of various applications.
  • Properties: Magnesite Dolomite brick offers good thermal resistance and anti-spalling performance purifying the steel by removing sulfur and phosphorus; while used in cement rotary kilns providing good coating protection to the kilns.
  • Application: Magnesite Dolomite brick is applied mainly in refining furnaces such as AOD, VOD, and ladles. Applied in the burning zone of cement refractory kiln as the replacement of magnesite chrome brick.
