What Are Magnesite Bricks? Understanding the Basics
Magnesite bricks, at their core, are alkaline refractory materials composed primarily of magnesium oxide (MgO), typically containing 80%-85% or more magnesia content. These specialized bricks are engineered to withstand extreme temperatures while maintaining structural integrity under intense industrial conditions.
The fundamental composition of magnesite bricks revolves around periclase (magnesium oxide) as the primary crystal phase, which provides their characteristic resistance to high temperatures and alkaline slags. The exact properties and performance characteristics vary depending on the specific type of magnesite brick and its manufacturing process.
LongKeter are several primary types of magnesite bricks, each with distinct application:
- Fired Mag Bricks:Long Keter supplying a comprehensive range of FIRED MAG BRICKS.It is made with fused
- Mag Chrome Bricks:Long Keter supplying a comprehensive range of Magnesia Chrome Brick, Mag Chrome Brick is mainly used in metallurgical industry, such as for building open-hearth furnace top, electric furnace top, finery out of furnace and all kinds of non-ferrous metal metallurgy furnace. Fused cast magnesite chrome brick is adopted for high temperature position of furnace wall in electric furnace with ultra high power. Magnesia chrome brick that made of synthetic compost is adopted for strong erosion area in finery out of furnace. Fused cast magnesite chrome brick or magnesia chrome brick that made of synthetic compost is adopted for strong erosion area of nonferrous metals flash smelting furnace. Besides, Magnesia Chrome Brick also can be used for burning zone in rotary cement kiln and regenerative chamber in glass furnace.
- Mag Carbon Bricks: Long Keter supplying a comprehensive range of Magnesia Carbon Bricks, Magnesia Carbon Bricks have been used in the slag line of refining ladle, and good results have been achieved. Magnesia carbon bricks are also used for the lining part of AC arc furnace, DC electrical arc furnace, converter and other parts.
- Mag Spinel Bricks: Long Keter supplying a comprehensive range of Magnesia Spinel Bricks are mainly used in non-ferrous smelting, transition zone before and after cement rotary kiln, high temperature zone of lime kiln, glass heat-accumulated type, top of reverberatory furnace, etc.
- Mag Calcium Bricks: Long Keter supplying a comprehensive range of Mag Calcium Brick (Dolomite Brick). Mag Calcium Brick is mainly used as lining material for AOD furnace, VOD furnace and LF furnace in steel making industry.
