Product Description

High refractoriness sintered magnesia brick good erosion resistance fused refractory magnesite brick for steelmaking furnace lining

Product Description

Magnesia Bricks Introduction 
 
Magnesium brick is an alkaline refractory material mainly composed of magnesium oxide, with a magnesium oxide content of up to 91%, and periclase as the main crystal phase. Meanwhile, it has high refractoriness at 2000ºC (3632ºF) and strong resistance to alkaline corrosion, they have excellent high-temperature mechanical strength and volume stability.

Magnesia Bricks Features
 

Magnesite 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.

1.High compressive strength
Strong erosion resistance and stable volume at high temperatures.

2.High load softening temperature
Good thermal conductivity, high fire resistance and load softening point.

3.High quality raw materials
Using excellent raw materials, it has good wear resistance at high temperatures and a long service life.

4.Processing customization
We can provide customized one-stop production and processing services according to customer requirements.

5.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.

6.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.
