Product Description

The fused-rebonded magnesia chrome brick has high temperature resistance, good corrosion resistance, thermal shock resistance and bulk stability under high temperature etc .The fused-rebonded magnesia chrome brick is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate.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.


 The fused-rebonded magnesia chrome brick mainly used in metallurgy(open hearth,EAF), non-ferrous (metall-urgyfurnace ) , buildings and materials (cement rotary kiln,glass kiln) etc.

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:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees.
Q:Process for producing magnesia chrome brick?
The process of firing magnesia chrome bricks is roughly the same as that of magnesia bricks. In order to remove the bricks during sintering, due to MgO and Cr2O3, Al2O3 or direct bonding of magnesia chrome bricks
Q:What are the environmental hazards of magnesia chrome refractory bricks?
Magnesia chrome brick with MgO and Cr2O3 as the main component of this kind of brick, high refractoriness, high strength, anti alkaline slag corrosion resistance, excellent thermal stability, has certain adaptability in industry wide application of now high temperature acid slag
Q:How much is magnesium chrome brick a ton?
Magnesium chrome bricks according to physical and chemical indicators in order to know the specific price, the production of magnesia chrome brick place a lot
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: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 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 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: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.
