Directly bonded magnesia-chrome brick/Used for VOD furnace, refining ladlearc furnace/AOD Furnace/Thermal shock
Product description:
Directly bonded magnesia-chrome brick is generally refers to by the impurity content of lower chromium ore and relatively pure magnesia, in 1700℃ above the temperature of the products, refractory grains between direct contact.
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.
Features:
The direct combination of magnesia-chrome brick has the characteristics of corrosion resistance, erosion resistance, spalling resistance, good slag resistance and thermal shock stability.Used for smelting nonferrous metals, pierrey-smith, Noranda, Ausmelt, Flash famace, electric steelmaking furnace, converter, VOD furnace, refining ladle, glass kiln, cement kiln, etc.
