Introduction:Magnesia-carbon bricks are made of fused magnesia or sintered magnesia, flake graphite, organic binders and antioxidants as raw materials, and various non-oxide additives are added. It is a composite refractory material combined with a carbonaceous binder.
Features:1. Good high temperature resistance.
2. Strong resistance to slag.
3. Good thermal shock resistance.
4. Low creep at high temperature.
Application:Magnesia-carbon bricks are mainly used for the lining of converters, AC electric arc furnaces, and DC electric arc furnaces, and the slag line of ladle.
