Magnesite chrome brick is one of our major products. Its market share has topped the home market, with a large amount of magnesite chrome bricks being exported to the international market.

Main Product:
☆ Ordinary Magnesite Chrome brick
  ■ Material and Technique: made from sintered magnesia and chrome ore and sintered at high temperature
  ■ Property: having higher bulk density and stronger thermal resistance than the magnesite brick
  ■ Application: used in cement rotary kilns, glass kiln regenerators, permanent lining of steel furnace permanent and refining ladle permanent lining of refining ladle.


☆ Directe-Bonded Magnesite Chrome brick
  ■ Material and Technique: made of low impurity chrome ore and high purity magnesia and fired at high temperature over 1700℃
  ■ Property: strong slag resistance and good performance under high temperature
  ■ Applied in cement rotary kilns, electric arc furnaces, and non-ferrous metal furnaces


☆ Rebonded Magnesite-Chrome brick and Semi-Rebonded Magnesite-chrome brick

  ■ Material and Technique: made with synthetic fused magnesia, shaped under high pressure and fired at ultra high temperature
  ■ Property: Thanks to the high purity of the raw material, the product has good high temperature performance, high thermal resistance, low air-permeability, and strong slag resistance
  ■ Application: used in tapping hole of AOD furnace, the lower vessel of vacuum chamber and snorkel of RH furnace, and the slag line of high temperature furnaces
  

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: 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?
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: 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?
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: 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 types of magnesia chrome bricks for industrial use?
It is possible to judge by the concrete kiln. The magnesium chrome bricks produced by real gold company are very good. Our factory purchased them the year before last, and their technicians were very professional, and gave us very good suggestions.
Q: With different capacitance magnesia brick brick
Fused magnesia brick brick has compact structure, high mechanical strength,
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?
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.
