Product Description

Electrofused semi - recombined magnesia - chrome brick/Used for steel smelting, refining ladle/VOD furnace/AOD furnace



Product description:

Magnesia-chrome brick made by electrofused magnesia-chrome sand as raw material is called recombined magnesia-chrome brick, and the product with partial electrofused magnesia-chrome sand is called semi-recombined magnesia-chrome brick.


Category of Refractory Brick/Fire Brick:

Magnesia-chrome brick is divided into ordinary magnesia-chrome brick, directly combined magnesia-chrome brick, electrofused semi-recombined magnesia-chrome brick and electro fused magnesia-chrome brick.



Accordi  According to the characteristics of microstructure high temperature crystal phase direct bonding, recombined and semi-recombined magnesia-chrome  bricks are the direct bonding bricks with higher direct bonding rate.They are  characterized by high strength, erosion resistance, erosion resist                      -ance, spalling resistance, good slag resistance and thermal shock stability.Mainly used for smelting nonferrous metals, pierrey-smith, Noranda,                  Ausmelt, Flash  famace, electric steelmaking furnace, converter, VOD furnace, refining ladle, etc.The recombined magnesia-chrome brick is more                suitable for the high erosion area of the furnace than the semi-combined magnesia-chrome brick.
