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:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick or clay brick, which type of high temperature refractory brick?
The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
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?
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: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: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: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: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 kiln
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.
