magnesia chrome brick refractory nozzles and blocks

Magnesia Chrome Brick, Magnesia Chrome Bricks,

Application:

It is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate. The domestic so called magnesia –Chrome bricks.

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.

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: 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 environmental hazards of magnesia chrome refractory bricks?: Some of the magnesia chrome bricks will be converted into Cr6+ when used, producing K2CrO4 and other toxic and carcinogenic compounds such as Cr3+

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: How many kinds of refractory bricks are there?: Magnesia chrome brick: Hang kiln, used for firing zone, the disadvantage is the poor thermal shock resistance, plus six Cr price is highly toxic, the production and use of the national magnesia chrome brick is gradually reduced, the brick production unit as soon as possible to find alternatives.

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?: Semi - combined magnesia chrome brick is a kind of refractory product made from partly fused magnesia chromite sand.

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: 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.

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.
