Magnesia-carbon bricks are made of high melting point carbon materials that are difficult to be infiltrated by slag as raw materialsand and high melting point alkaline oxide magnesia (melting point 2800°C) ,various non-oxide additives are added. Non-burning carbon composite refractory material combined with carbon binder.
2. Product Feature
Magnesia-carbon bricks have good high temperature resistance, strong slag resistance, good thermal shock resistance, and good low temperature and high temperature creep performance.
3.Product Application
Magnesia-carbon bricks are widely used and can be used in key parts of thermal equipment such as steel-making converters, electric arc furnaces, ladles, and refining furnaces outside the furnace.
