Product Description
Magnesia Chrome Brick are direct-bonded and made from high grade magnesite clinker and chrome oxide. By high pressure shaping and high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling resistance. The low-basic neutral nature gives itself a good slag resistance when servicing low-acid feed furnaces.
The fused-rebonded brick are made of fused mgo chrome clinker,its a realistic lining material for refining furnace, electric furnace, glass melting furnace,AOD COD RH etc.
Features
- Good thermal shock resistance performance
- Excellent resistance in slag abrasion
- Good cold crush strength
- Higher temperate resistant with good refractoriness
- Higher grade of Chrome ore raw material
- Lower apparent porosity
- Lower impurity content
Applications
- Nonferrous Metal Furnace
- Rotary & Shaft Kiln
- AOD COD RH
- EAF & Ladle
- Hot-blast Furnace
- Glass Kiln.
Specifications
- MgO and Cr2O3 content range from 77% to 83%
- Widely used throughout AOD COD RH EAF & Ladle Nonferrous Metal Furnace
