Magnesia alumina brick is a kind of basic refractory material which is manufactured by using magnesia and little industrial alumina oxide or bauxite as raw materials.Magnesium aluminum spinel brick is a low calcium content of high quality magnesia and industrial alumina powder as the main raw material, by high pressure forming, high temperature firing.
1.Higher temperate resistant with good refractoriness.
2.Good thermal shock resistance performance.
3.Excellent resistance in slag abrasion.High quality 80% magnesia alumina bricks
4.Outstanding resistance to chemical attack.
5.Outstanding thermal-shock resistance.
6. Good cold crush strength.Magnesium oxide refractory brick for magnesia steel ladle
7. Low bulk density, low thermal conductivity, good thermal insulation performance
Applications
· Metal Line, Free Board for General Ladle.
· Furnaces of metallurgy industry, heat treatment furnace.
· Furnaces of chemical industry and construction industry.
· Furnace of incineration of garbage, recirculating fluidized bed furnace.Magnesium oxide refractory brick for magnesia steel ladle
· The top of steel making open-hearth furnace and EAF, high temperature tunnel kiln, large-scale cement rotary kiln and non-ferrous metal smelting furnaces.
