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?: Different grades of burned magnesia brick is mainly made of magnesia binder with different taste, there is not a big difference. However, the physical and chemical properties of binders should be controlled well!

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: 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?: High purity aluminum is 99.99, the first is not pollution, the stove is high magnesia brick masonry, 95% and 97% purity magnesia brick is for a long time did not find a good bit of fireclay, do not know what to build, now used light burned US powder and heavy burned magnesium plus brine built, with 2 months a griddle doesn't stick on magnesium brick, a touch off, there is no good sintering

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: Magnesia brick (magnesite brick) basic refractories Magnesium Oxide content of more than 90%, with the main crystalline phase of periclase. 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: Magnesia brick (magnesite brick) basic refractories Magnesium Oxide content of more than 90%, with the main crystalline phase of periclase

Q: Process for producing magnesia chrome brick: The oxide of iron reacts to produce a loose effect caused by the expansion of the spinel. Also, the magnesia chrome brick can be made from the synthetic common sintered material. In addition, there are non burned magnesia chrome bricks, for example, non burned magnesia chrome bricks combined with inorganic magnesium salt solutions. The unfired magnesia chrome brick has the advantages of simple production process, low cost and good thermal stability, but the strength of the high temperature is far less than that of the burnt brick. In the late 50s, a so-called "direct bonding" magnesia chrome brick was developed. The characteristics of this brick raw material is pure, high firing temperature, periclase and spinel phase with high temperature directly, silicate and other low melting point phase for island distribution, therefore, significantly improve the high temperature strength and slag resistance of brick.

Q: Magnesite chrome brick, magnesia chrome brick indicators? What is the price?.: According to the actual situation, design the brick you need, and the price of brick is determined by the index.
