Q:What are the types of magnesia chrome bricks for industrial use?

1. burned magnesia chrome bricks 2. magnesia chrome bricks 3. semi bonded magnesia chrome brick and magnesia chrome brick generally is the three

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.In addition, magnesite brick and electric arc furnace melting magnesium chromium material by direct casting (see Figure microstructure, color), fused magnesia chrome brick material produced by the process of melting particles combined with magnesia chrome brick etc..

Q:What are the main raw materials of magnesia chrome bricks?

At present the most widely used are magnesium aluminum alloy, followed by magnesium manganese alloy and magnesium zinc zirconium alloy. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors. In practical metals, it is the lightest metal, and the specific gravity of magnesium is about 2/3 of aluminum and 1/4 of iron. It is the lightest metal in practical metals, high strength and high rigidity.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?

I produce clay bricks, and my bricks stand at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q:What are the differences between magnesium chrome bricks, such as direct bonding, re bonding, semi bonding, CO sintering and chemical bonding? Hope expert advice..

Direct bonded magnesia chrome brickThe loose effect caused by the expansion of spinel when the oxide of magnesia brick is directly reacted with the oxide of iron can also be used to make magnesia chromite brick with 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 much is magnesium chrome brick a ton?

The price of bricks in different places is not the same. The average price is about 3500 yuan

Q:With different capacitance magnesia brick 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.

Q: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:What are the environmental hazards of magnesia chrome refractory bricks?

Nowadays, the use of magnesia chrome bricks, especially in cement kilns in the construction industry, has been required to be free of chromium, and the cement products shall not be tested with chromium.

Q:How many kinds of refractory bricks are there?

Dolomite brick: coating performance, good erosion resistance, but how many bricks f-CaO, yasumizu, it is difficult to transport and storage, production with less.
