Q: Brick price?: Refractory brick series sintered magnesia brick, magnesia chrome brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, unburned magnesia chrome brick, magnesia brick, magnesia calcium brick, magnesia brick, and al2o3-mgo-c bricks.

Q: The index of magnesia brick: Room temperature compressive strength≥（MPa）（15－25－）24.5－24.5－24.5－24.5－40－40－40

Q: High purity magnesia brick masonry mortar for what?: Always! There is no 800 degrees can be sintered chamotte? As long as the dregs and do not break the aluminum content, the magnesia brick stick together can!

Q: Manufacture of various refractory magnesia brick mainly comes from Magnesium Oxide, what kind of ore?: The ore quality requirements of MgO = 41%, CaO = 6%, SiO2 = 5%. The resources of magnesite in China are rich. The types of deposits include sedimentary metamorphic deposits, sedimentary hydrothermal metasomatic deposits and weathering leaching deposits.

Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q: With different capacitance magnesia brick brick: It has good thermal stability, corrosion resistance and spalling resistance. Widely used in converter, arc furnace and other industrial furnace lining refractory.

Q: Magnesia brick: General can be divided into sintered magnesia brick (also called burnt magnesia brick) and chemically bonded magnesia brick (also known as the two major categories of not burned magnesia brick). Purity and high firing temperature of magnesia, due to the direct contact of periclase grains, known as direct bonded magnesite brick; made of fused magnesia bricks called electrically fused magnesite brick.

Q: How to identify the fused magnesia brick and sintered magnesia brick: Burnt magnesia brick is made of high quality sintered magnesia as main raw materials, paper pulp as binder. After mixing and high pressure molding, it is fired in a high temperature tunnel kiln over 1550 degrees celsius. It has good thermal stability, corrosion resistance and spalling resistance. Widely used in converter, arc furnace and other industrial furnace lining refractory.Fused magnesia brick brick has compact structure, high mechanical strength, low impurity content, mainly used for the storage of large glass kilnHigh temperature area of the room. The fused magnesia is made of high quality magnesia as raw material. It is made by melting. The English name is fused magnesite. Magnesium hydroxide from magnesite or brucite or from sea water is calcined at high temperature. Strong hydration resistance.

Q: How do you differentiate between the two clearly? Where is the key? Thank you: Magnesia brick (magnesite brick) basic refractories Magnesium Oxide content of more than 90%, with the main crystalline phase of periclaseGeneral can be divided into sintered magnesia brick (also called burnt magnesia brick) and chemically bonded magnesia brick (also known as the two major categories of not burned magnesia brick). Purity and high firing temperature of magnesia, due to the direct contact of periclase grains, known as direct bonded magnesite brick; made of fused magnesia bricks called electrically fused magnesite brick.

Q: Combined with the ordinary clay brick and magnesia brick as an example, the existence of impurities in minerals and refractories production main components of the formed liquid relative what affect the performance.: Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
