Magnesia Carbon Bricks have been used in the slag line of refining ladle, and good results have been achieved. Magnesia carbon bricks are also used for the lining part of AC arc furnace, DC electrical arc furnace, converter and other parts.

The bricks with MgO 95% or more in content take the secondary burning dead burned magnesia or electro fused magnesia as the raw material and burned under the condition of ultra high temperature. They have the features of highly directly bonded and corrosion-resistance and widely used in various kinds of high temperature furnaces.

Key Features for Magnesia Carbon Bricks
