High Quality Fused Magnesia Chrome Brick

Description of Fused Magnesia Chrome Brick：

Magnesite chrome brick has magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient, periclase and spinel as main mineral components of refractory products.
1.Common Magnesite chrome brick is made by sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate.
2.Direct-bonded Magnesite chrome brick is made by chrome ore with low content of impurities and pure magnesite,firing at the temperature above 1700°C.
3.Semi-rebonded and Fuse-rebonded magnesite chrome brick are made by fused magnesite chrome sinter.

Fused Semi-Recombined Magnesia Chrome Brick

Semi-recombined magnesia-chrome bricks are dense, low porosity, high temperature strength, better thermal shock resistance than recombined magnesia-chrome bricks, and have strong slag erosion resistance.

Features of Magnesia Chrome Brick
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped and special shaped bricks.
5. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.

Application of Direct Bond Magnesia-Chrome Bricks
It’s mainly applied to line the sintering zone of the new dry-processing of cement kilns and glass tank furnaces as checkers and the other industrial furnaces.
Fuse-Rebonded Magnesia-Chrome Brick
Main Application:It’s suitable for lining of the slag zone area of refining furnaces of VOD,SKF.
Semi-Rebonded Magnesia-Chrome Brick
Main Application:It’s widely used for every industrial furnaces of the metallurgical and building materials industry.
