- 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?
- In addition to the brine binder burned magnesia brick and sulfite pulp waste liquid, Magnesium Sulfate solution binder is generally around 3%
- 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
- Room temperature compressive strength≥（MPa）（15－25－）24.5－24.5－24.5－24.5－40－40－40
- 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?
- 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: 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: 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: Magnesia brick
- General 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: 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: 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
