Magnesia brick (magnes brick) Magnesia content of more than 90% to periclase-based alkaline refractory

Generally can be divided into sintered magnesia brick (also known as firing magnesia brick) and chemical combination of magnesia brick (also known as not burning magnesia brick) two categories. The magnesia brick with high purity and high calcination temperature is called the direct combined magnesia brick due to the direct contact of the periclase crystal grains. The brick made of fused magnesia as the raw material is called the fused fused magnesia brick.

Magnesia brick has high refractoriness, good alkali-resistant slag performance, load softening start temperature, but poor thermal shock resistance. The sintered magnesia brick is prepared from the brick made of magnesia brick by crushing, mixing, kneading and molding, and is fired at a high temperature of 1550-1600 DEG C, and the firing temperature of the high-purity product is more than 1750 DEG C. Do not pour magnesia magnesia in magnesia by adding the appropriate chemical binding agent, after mixing, forming, drying and made.

Burn into a high-quality sintered magnesia magnesia magnesia as the main raw material to pulp as a binder. After mixing and high-pressure molding, in 1550 ℃ high temperature tunnel kiln firing. Has good thermal stability, anti-erosion and anti-spalling properties. Widely used in converter, electric arc furnace and other industrial furnaces as lining refractory materials.

Fused magnesium brick has the brick structure compact, high mechanical strength, low impurity content, etc., mainly for large glass kiln thermal storage

High temperature area of the room. Fused magnesia is made of high quality magnesia made by melting and fused English name fused magnesite. Magnesite, water magnesium ore or magnesium hydroxide extracted from seawater by high temperature calcination. Strong resistance to hydration.
