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 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: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:Magnesium chrome brick price?

In the brick factory products are now sold throughout the country and exported to the United States, South Africa, India, Germany, Canada, Ukraine, Japan and other countries, has been recognized and highly refractory materials in the world market.

Q:What is a half combination of magnesia chrome bricks?

Opacifying particles as periclase spinel crystal structure, fully developed, as part of account of solution structure and matrix.

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..

The process of firing magnesia chrome bricks is roughly the same as that of magnesia bricks. In order to eliminate the brick during firing, due to MgO and Cr2O3, Al2O3

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:Magnesia chrome brick

Magnesia chrome brick to Magnesium Oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient, refractory periclase and spinel as main mineral components of products. The bricks have high refractoriness, high temperature strength, strong resistance to alkaline slag, good thermal stability, and certain adaptability to acid slag. The main raw materials for making magnesia chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible, chrome iron ore chemical composition requirements: Cr2O3:30 - 45%, CaO = 1 ~ 1.5%.

Q:What is the difference between magnesia chrome brick and direct bonded magnesia chrome brick?

The magnesium chromium brick with the direct bonded magnesia chrome brick is different: 1 with the purity of magnesia (raw materials) 2: the sintering temperature of common magnesia chrome brick sintering temperature at 1550 DEG ~1600 DEG, direct the magnesium chromium brick sintering temperature is over 1700 DEG C, because of its more than 1700 DEG C, magnesia chrome brick microstructure occurred change, and periclase chromium ore directly combined, so called direct bonded magnesia chrome brick
