Magnesia Brick
Brief Description
Magnesia brick is basic refractory brick materials whose MgO content are more than 90% and adopt periclase as the principal crystalline phase. Magnesia brick generally can be classified into sintered magnesia brick (also known as fired magnesia brick) and chemically bonded magnesia brick (also known as non-fired magnesia brick).
Magnesia brick is mainly used in steel-making alkaline furnace, electric furnace hearth and furnace wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesia brick and cement kiln lining, glass kiln regenerators checker bricks,etc. Any Interests, please contact us for more information and detailed quotation.
