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: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: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: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: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:The index of magnesia brick
Room temperature compressive strength≥(MPa)(15-25-)24.5-24.5-24.5-24.5-40-40-40
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:How to identify the fused magnesia brick and sintered magnesia brick?
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: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
