- 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?
- 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
- 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: 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: Process for producing magnesia chrome brick
- The oxide of iron reacts to produce a loose effect caused by the expansion of the spinel. Also, the magnesia chrome brick can be made from the synthetic common sintered material. In addition, there are non burned magnesia chrome bricks, for example, non burned magnesia chrome bricks combined with inorganic magnesium salt solutions. The unfired magnesia chrome brick has the advantages of simple production process, low cost and good thermal stability, but the strength of the high temperature is far less than that of the burnt brick. In the late 50s, a so-called "direct bonding" magnesia chrome brick was developed. The characteristics of this brick raw material is pure, high firing temperature, periclase and spinel phase with high temperature directly, silicate and other low melting point phase for island distribution, therefore, significantly improve the high temperature strength and slag resistance of brick.
- Q: How do you differentiate between the two clearly? Where is the key? Thank you

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 kiln
- 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.
