Application of Magnesia Alumina Carbon Brick
Currently dolomite bricks/magnesia calcium brick are used as refractory lining of treatment and casting ladles in many steel plants worldwide. Thanks to its low oxidation potential, does not transfer oxygen to the liquid steel, therefore it makes desulphurization easier, it is highly compatible with basic slag, it increases the yield of Fe-alloys and can grant long service life at optimal refractory costs. The AOD and VOD process are nowadays the most common ways to produce stainless and alloy steel grades. The dolomite and dolo-magnesite refractories are considered as the most common lining for such a metallurgical process, especially for their attitude to desulphurization, to work with silica-based slag and to achieve the best performances in terms of costs and service life. We offers a wide range of fired and C-bond dolomite-based bricks, suitable for many metallurgical treatments.

- Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- 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: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: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: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: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:Brick price?
- There are various series of unshaped refractory gunning, magnesia ramming material, mending material, coating material, dry lining material, composite refining agent, covering agent, tundish and tundish slag wall, ladle drainage sand and electric furnace taphole filler etc..
- 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: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: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
