High Alkali Resistance Magnesite Brick

High Alumina Refractory Cement for Furnaces is manufactured through fusing high quality raw magnesite in electric arc furnace with the characteristics of big crystal, dense structure and strong corrosion resistance. As an excellent basic refractory raw material, its MgO content is between 87 – 98%.

High Alumina Refractory Cement for Furnaces (Big Crystal) whose MgO content is between 97 – 99% is widely used in refractory industry. Meanwhile, it is also an excellent high-temperature endurable insulating material.

Q: What is the ratio of magnesia refractory bricks to brine? For example, what is the difference between the 97 and 95 with 92 brick brick brick material mixed with brine ratio?: In addition to the brine binder burned magnesia brick and sulfite pulp waste liquid, Magnesium Sulfate solution binder is generally around 3%

Q: The index of magnesia brick: indexMGe-20 MGe-16 MGe-12 MMGe-8 DBMK-A DBMK-B DBMK-C MgO≥（%） 40 45 55 60 80 80 80 Cr2O3≤（%） 20 16 12 8 6-8 6-8 6-8 SiO2≤（%） --- --- --- --- 2.0 2.5 3.0

Q: High purity magnesia brick masonry mortar for what?: You try a mixture of aluminum phosphate. It itself is the main component of aluminum, which can not cause pollution. We use high temperature electric stove to bond with this.But this 800 degree won't be sintered. It won't sinter until more than 1000 degrees.

Q: Manufacture of various refractory magnesia brick mainly comes from Magnesium Oxide, what kind of ore?: Manufacture of various refractory magnesia brick Magnesium Oxide, mainly from magnesite.

Q: With different capacitance magnesia brick 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.

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 have high refractoriness, alkali slag good performance, high load softening temperature, but poor thermal shock resistance. The sintering magnesia brick brick magnesite as raw material, crushing, proportioning, mixing, forming, in 1550 ~ 1600 degrees firing, high purity products firing temperature is over 1750 DEG C. Don't add chemical bond magnesia brick is appropriate in magnesia, through mixing, molding and drying.

Q: Magnesite chrome brick, magnesia chrome brick indicators? What is the price?.: If you want to know the indicators of chrome brick, magnesia chrome brick must know you are in what furnace above, there is in what position

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.
