Magnesia olivine brickl/Used in non-ferrous melting furnace/High fire resistance and strong corrosion ability
Product description:
Products made from calcined peridotite and serpentine are called olivine bricks.In order to improve its high temperature performance, usually add 20%-40% of sintered magnesia, by batching, molding, high temperature burning into the magnesia peridot brick.
Category of Refractory Brick/Fire Brick:
Magnesia olivine brick
Features:
Magnesia peridot brick has a certain resistance to alkaline slag, high fire resistance and softening temperature under load, strong corrosion ability of antioxidant iron, more used in non-ferrous melting furnace, steelmaking open hearth regenerative chamber and cement rotary kiln lining.
