- 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: The index of magnesia brick
- indexMGe-20 MGe-16 MGe-12 MMGe-8 DBMK-A DBMK-B DBMK-C MgO≥（%） 40 45 55 60 80 80 80 Cr2O3≤（%） 20 16 12 8 6-8 6-8 6-8 SiO2≤（%） --- --- --- --- 2.0 2.5 3.0
- 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: 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: 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: 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: 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 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?.
- According to the actual situation, design the brick you need, and the price of brick is determined by the index.
- 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.
