General Information of Magnesite Chrome Brick for Furnace
Burnt magnesia-chrome bricks are made from high quality mag-nesia and chrome concentrate, cr2o3 content can be adjusted accord ing to different requirements. The bricks have good thermal stability and high temperature performance, and are widely used in cement kilns and non-ferrous rnetal metallur-gical furnaces and so on. High temperature burnt directly bonded magnesia-chrome bricks, semi-rebonded magne-sia-chrome bricks and rebonded magnesia-chrome bricks are made from low impurity raw materials. All or part of raw ma-terials are preburnt or electro fused. The best proportioning, high pressure moulding, ultra high temperature and good vol-ume stability. The bricks are widely used in large cement ro-tary kiln, and secondary refining units such as RH, VOD, AOD furnaces, non-ferrous metal met-allurgical furnaces, glass tanks and so on.
Direct-bonded magnesia chrome brick is made of low impurity chrome ore and high purity magnesia and sintered at high temperature over 1700℃.
Semi-rebonded and rebonded magnesia chrome bricks are made partially or fully of synthetic fused clinkers. They are shaped under high pressure and sintered at very high temperature.

- 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?
- The price of bricks in different places is not the same. The average price is about 3500 yuan
- Q: Magnesia chrome brick
- Magnesia chrome brick to Magnesium Oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient, refractory periclase and spinel as main mineral components of products. The bricks have high refractoriness, high temperature strength, strong resistance to alkaline slag, good thermal stability, and certain adaptability to acid slag. The main raw materials for making magnesia chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible, chrome iron ore chemical composition requirements: Cr2O3:30 - 45%, CaO = 1 ~ 1.5%.
- 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 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
- 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 magnesia chrome bricks are divided into ordinary magnesia chrome bricks, direct bonding magnesia chrome bricks, half bonded magnesia chromite bricks, fused magnesia chrome bricks, fused magnesia semi bonded magnesia bricks, and unburned magnesia chrome bricks
- 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.
