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: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?
- The ore quality requirements of MgO = 41%, CaO = 6%, SiO2 = 5%. The resources of magnesite in China are rich. The types of deposits include sedimentary metamorphic deposits, sedimentary hydrothermal metasomatic deposits and weathering leaching deposits.
- Q:How do you differentiate between the two clearly? Where is the key? Thank you
- Magnesia brick (magnesite brick) basic refractories Magnesium Oxide content of more than 90%, with the main crystalline phase of periclaseGeneral 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: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:The index of magnesia brick
- Room temperature compressive strength≥（MPa）（15－25－）24.5－24.5－24.5－24.5－40－40－40
- 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: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: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..
