Product introduction of magnesia-zirconia bricks
Magnesium-zirconium bricks use high-purity fused magnesia and synthetic magnesia-zirconia bricks sand as raw materials. After high-pressure molding and high-temperature firing, they have 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.
Product characteristics of magnesia-zirconia bricks

Characteristics and application of magnesia-zirconia bricks brick
The magnesia-zirconia bricks brick is a two-phase eutectic composite material composed of MgO and ZrO2. Magnesium-zirconium brick production process The production of magnesia-zirconia bricks bricks uses magnesia-zircon sand as raw materials to produce materials with uniform distribution of MgO and ZrO2. This type of material is to first synthesize magnesia zircon sand. It is to obtain sintered/fused magnesia zircon sand after mixing MgO and ZrO2 raw materials as required-fine grinding-ball (blank)-sintering / electric melting. Then the magnesia-zirconia bricks sand is crushed, smashed, classified, batched, mixed, formed, and fired to obtain a ZrO2 composite magnesia refractory material with uniform MgO/ZrO2 distribution. It can be seen that their production process is the same as that of magnesia refractories. ZrO2 is combined with magnesia to produce magnesia-zirconia bricks bricks. The production method of this type of material is to mix ZrO2 into magnesia to produce ZrO2 composite magnesia refractory materials with different MgO/ZrO2 ratios. Their production process is basically the same as the production of magnesia-chromium refractories. Special magnesia-zirconia bricks bricks. The production process of this type of material is different from ordinary magnesia refractory materials in that the surface of the magnesia refractory material aggregate particles is coated with a refractory material 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 magnesia-zirconia bricks bricks with 20% SiO2 content actually belong to the MgO-2MgO·SiO2-ZrO2 refractory. The combined matrix layer in the material has high corrosion resistance. The corrosion resistance of this brick has been confirmed in the use of regenerator and melting chamber.
