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: 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?: 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: 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: Mainly used for basic open hearth, furnace bottom and furnace wall oxygen converter steelmaking, the permanent lining of non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln, furnace bottom and furnace wall, glass furnace regenerator etc..

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?.: 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.: The main varieties of common magnesia brick, magnesia brick, magnesia brick, magnesia brick high pure grade. Product main mineral phase is periclase, volume has high stability and anti erosion ability. Literature is widely used in steelmaking, non-ferrous metal smelting and other high-temperature industrial furnace.
