Product Description
Magnesia refractory carbon brick is resin-bonded brick made from dead-burned, fused magnesia and graphite.Magnesia refractory carbon brick has good performance in thermal resistance, corrosion resistance and spalling resistance, mostly used in converters, EAFs, ladles and refining furnaces.

*Higher temperate resistant with good refractoriness
*Excellent resistance in slag abrasion
*Good thermal shock resistance performance   
*Lower creep in high temp
*Not wet with slag easily

Magnesia carbon refractory brick is mainly used for steelmaking oxygen converter lining, the steel export, high power electric furnace wall hot spots, and the furnace refining furnace lining, sheng steel ladle slag line position and also used for the lining of converter, AC arc furnace, DC electric arc furnace, ladle slag line,etc.

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: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:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick or 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
Fused magnesia brick brick has compact structure, high mechanical strength,It is mainly used for thermal storage of large glass furnaceHigh temperature area of the room.
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: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: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: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: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.
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
