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: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: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 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: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.
Q:Process for producing magnesia chrome brick
The fine powder compacts after calcination produced by magnesia - chrome ore grinding method, brick with magnesia coarse particles, are effective measures to eliminate the effect of loose. Compared with the common magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, higher softening temperature and higher flexural strength. Compacts with chrome magnesite powder, magnesia chrome brick by synthetic magnesia chrome sand made of high-temperature calcination, slag resistance and high temperature strength are better than other magnesite chrome brick.
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: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: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

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.
