Magnesia Zirconium Brick

Magnesia zirconium brick has excellent corrosion resistance to alkali metals, oxides and sulfides. The product is made of fused magnesia sand and zirconium sand and their alkaline materials. The product has a high density (bulk density) greater than 3.08 g/cm3). It also resists alkaline corrosive atmosphere and alkaline slag corrosion and is widely used in glass melting furnaces, regenerators, cement kilns, electric steel furnaces and non-ferrous metal smelting. The difference between the production process of magnesia zirconium bricks and ordinary magnesia refractory materials is that the surf

Magnesia Zirconium Brick Details

The difference between the production process of magnesia zirconium bricks and ordinary magnesia refractory materials is that the surface of the magnesia refractory material aggregate particles is coated with refractory materials with ZrO2 as the main component, and the surface of each particle is uniformly formed into a thin The ZrO2 coating is dried and fired to form a strong ZrO2 sintered layer between the periclase particles. The product has good performance. The material does not produce cracks, cracks, peeling, and good thermal stability during use. The combined matrix layer in the material has high corrosion resistance, and the corrosion resistance of this brick has been confirmed in the use of the regenerator and the melting chamber.

Application

Magnesia zirconium bricks are used in the heat storage chamber of the glass furnace.

Magnesium and zirconium fusion method

1. Add immediately

According to the application of magnesia zirconium corundum bricks and the ratio of related refractory bricks and the purity regulations of Mgo-Zro2 brick products, appropriate raw materials are selected from industrial production requiring zirconia, zirconia, desiliconized zirconium, zirconium and other raw materials. Add it now.

2. Electric fusion manufacturing method

Mgo-Zro2 sand is made by electric fusion or calcination, and then the raw material of magnesia brick which must be added.

3. Surface coating method

The surface layer of magnesium oxide particles is coated with this refractory material. The key is to produce the surface layer of each object on the uniform chromatography of zirconia and zirconium.
