Product Description:

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:How many kinds of refractory bricks are there?
High aluminum brick: Al2O3 content more than 75 higher than that of the refractory clay brick, anti corrosion resistance, suitable for cement kiln etc., long service life, but high price.
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
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 differences between magnesium chrome bricks, such as direct bonding, re bonding, semi bonding, CO sintering and chemical bonding? Hope expert advice..
Direct bonded magnesia chrome brickThe loose effect caused by the expansion of spinel when the oxide of magnesia brick is directly reacted with the oxide of iron can also be used to make magnesia chromite brick with 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:Magnesium chrome brick price?
Magnesia brick factory with strong technology foundation as the basis, has developed more than 40 varieties of products, including building materials, non-ferrous metals, iron and steel and other fields, won the national high-tech products nearly a dozen, four patents, including magnesia spinel brick reached the world advanced levelFrom July 2006 to now won the high-tech enterprises in Liaoning province; National Standardization Management Committee issued the "adopting international standard product certificate" enterprises; in 2009 passed the ISO9001 quality management system certification; the famous brand products of Liaoning Province certificate certificate and certificate management, the reliable guarantee for the quality of products.
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: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: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: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: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.
