Magnesia--Zirconia brick

Magnesia zirconium brick is the main raw material of high purity fused magnesia, zirconium silicate and synthetic sand.It is made by high pressure forming and sintering.Due to the addition of ZrO2, the surface of MgO refractory aggregates was formed uniformly, and the main component of ZrO2 was thin coating.With the increase of temperature, the solid ZrO2 sintering layer is formed by the critical mass of magnesia granule.Products has a good practicability, in use process does not produce crack, crack, peeling, good thermal stability, material combined with the matrix layer with high corrosion resistance, alkali resistance and resistance to oxidation reduction ability.The corrosion resistance of this brick has been confirmed in the melting chamber and heat storage room of the glass melting kiln.Due to its high temperature, its structure is compact, porous and evenly distributed, so it has high compressive strength, anti-permeability, mechanical stress and abrasion resistance.Applicable to: glass kiln, melting room, heat storage room, cement kiln, steelmaking furnace and non-ferrous metal smelting furnace etc.In recent years, the application of the equipment on the equipment of limekiln has been extended, and the effect is good.
