magnesia carbon bricks
Magnesia carbon bricks (Mag carbon bricks) are made from high melting point basic magnesium oxide, high melting carbon which is difficult to be embellish by the slag and a variety of non oxide additives, making non carbonaceous composite magnesia carbon refractory bricks by combining with carbonaceous binder. As composite refractories, magnesia (mag) carbon bricks effectively make the use of the strong slag erosion ability of magnesite clinker as well as high thermal conductivity and low expansibility of carbon to off sets the biggest weakness of poor anti-stripping performance. They have high temperature plasticity.
Magnesia carbon bricks are used in the slag line of refining ladle, Mag carbon bricks are also used for the lining part of AC arc furnace, DC electrical arc furnace, converter and other parts.
PROPERTIES OF MAG CARBON BRICKS
- Good high-temperature performance.
- Strong slag resistance.
- Good thermal shock resistance.
- Low creep at high temperature.
- Good anti-stripping ability.
- Anti-stripping performance.
- Good wear resistance.
- Good thermal conductivity.
