- 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: 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?
- Always! There is no 800 degrees can be sintered chamotte? As long as the dregs and do not break the aluminum content, the magnesia brick stick together can!
- Q: With different capacitance magnesia brick brick
- It has good thermal stability, corrosion resistance and spalling resistance. Widely used in converter, arc furnace and other industrial furnace lining refractory.
- 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 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 (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?.
- 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.
- 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.
