Product Description:

Cement Kiln Magnesite Bricks  

 

CMAX Magnesia chrome bricks are made from chrome and magnesia. Magnesia chrome brick is mainly made from sintered magnesia and chrome-oxide, by high pressure shaping and chrome-oxide,by high pressure shaping and high temperature firing.According to different requirements the contents of the Cr2O3 can be changed. The product has good specifications for the shock resistance and high temperature performance. It's characterized by the small thermal expansion.The good thermal shock resistance and slag resistance.It is widely used for many industrial furnaces and kilns such as cement kilns,open-hearth furnace and melting furnace for nan-ferrous metals.Extra high temperature firing direct bonded,rebounded,rebounded and semirebonded magnesia-chrome brick,which are made from purity material all or part of the material that is synthesizeed through fusion,pressed with fine ingredients and high pressure and sintered by extra high temperature.

 

 

Product Applications:

Magnesia chrome bricks are ideal for use in the below applications 

Metallurgy industry of open-hearth furnace top , electric furnace roof, Mixer linings etc.

RH, VOD, AOD, and other refining installations;

Non-ferrous metallurgical furnace, vacuum treatment equipment;

Building materials , glass furnace regenerator; cement rotary kiln calcination etc.

 

Product Advantages:

CNBM has success in its magnesia chrome bricks due to their cost-effectiveness and excellent insulating properties. The refractoriness of magnesia chrome bricks are more than 2000°C, and the refractory under load is a above 1550°C.Good steady volume in high temperature, the performance of meeting sudden cold and sudden hot is better than magnesia bricks. 

 

Main Product Features:

Low porosity, high compressive strength, flexural strength of high pressure, good bulk stability;

Good thermal shock resistance, anti-spalling

Easy-to-skin hanging in the kiln, and low thermal conductivity;

High temperature of refractoriness under load.

Ultra-high-temperature firing, high direct binding rate, high refractoriness and corrosion resistance.

Strong resistance against alkaline substances, the acid resistance better than the magnesia refractories.

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: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: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: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
Mainly used for basic open hearth, furnace bottom and furnace wall oxygen converter steelmaking, the permanent lining of non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln, furnace bottom and furnace wall, glass furnace regenerator etc..
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: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: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 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.
