Magnesium-carbon bricks are made of high-melting alkaline oxide magnesium oxide (melting point 2800℃) and high-melting carbon materials that are difficult to be infiltrated by slag, and various non-oxide additives are added. A non-burning carbon composite refractory material combined with a carbon binder. Magnesia carbon bricks are mainly used for lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladle.
As a composite refractory material, magnesia carbon bricks effectively utilize the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, which compensates for the biggest disadvantage of poor spalling resistance of magnesia
Advantage:
1. Good high temperature resistance
2. Strong resistance to slag
3. Good thermal shock resistance
4. Low high temperature creep
Application:
The refractory materials used in the early ladle slag line were directly combined with magnesia-chrome bricks, and fused and combined with high-quality alkaline bricks such as magnesia-chrome bricks. After the successful use of MgO-C bricks in the converter, the refining ladle slag line also began to use MgO-C bricks, and achieved good results. China and Japan generally use resin-bonded MgO-C bricks with a carbon content of 12% to 20%, while Europe mostly uses pitch-bonded MgO-C bricks with a carbon content of about 10%.
