Product description
Material and Technique
Magnesia dolomite bricks/magnesia calcium bricks for AOD funace use synthetic dolomite sand as raw materials, selecting MgO/ CaO ratio in accordance with different needs, which are produced by high heat sintering and vacuum pressure impregnation pitch or paraffin treatment.
Magnesia dolomite bricks are of alkaline refractory products with a higher MgO content. Generally, MgO content of magnesia dolomite bricks is beyond 35%, then CaO content is more than 40%. In addition, Magnesia dolomite bricks also contain other impurities, such as SiO2, Al2O3, Fe2O3, etc.
Properties
Magnesia dolomite bricks for AOD furnace have good resistance to elevated temperatures and high slag resistance.
Application
As AOD furnace refractories, magnesia dolomite bricks are increasingly being used as linings for every part of AOD furnace, such as trunnion, tuyere, slag line, wall, bottom and furnace end.

- 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: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: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.
- 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: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?
- Opacifying particles as periclase spinel crystal structure, fully developed, as part of account of solution structure and matrix.
- 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
- 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: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:What are the environmental hazards of magnesia chrome refractory bricks?
- Nowadays, the use of magnesia chrome bricks, especially in cement kilns in the construction industry, has been required to be free of chromium, and the cement products shall not be tested with chromium.
