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?

Magnesium alloys are alloys based on magnesium and other elements. Its characteristics are: small density (1.8g/cm3 magnesium alloy or so), high specific strength, high modulus of elasticity, good heat dissipation, good shock resistance, greater impact load capacity than aluminum alloy, good resistance to organic and alkaline corrosion. The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium.

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 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:With different capacitance magnesia brick brick

Hello, the magnesium chromium brick into common magnesia chrome brick, magnesia chrome bricks, half magnesia chrome brick, magnesia chrome brick, semi fused magnesia chrome brick, unburned magnesia chrome brick, magnesia chrome brick and magnesia chrome brick and directly combined with the distinction lies in 1: containing magnesia (raw material) the purity of 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 change and periclase chromium ore directly combined, so called direct bonded magnesia chrome brick. The performance of direct bonding magnesia chrome brick is better than that of common magnesia chrome brick

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.

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

The performance of direct bonding magnesia chrome brick is better than that of common magnesia chrome brick.
