Magnesia chrome brick is an alkaline refractory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosphere. It can also be made into non-burned brick by chemical bonding agent such as water glass.
According to the raw materials and process characteristics of the products, it can be divided into silicate-bonded magnesia-chrome bricks, direct-bonded magnesia-chromium bricks, re-combined magnesia-chrome bricks, semi-recombined magnesia-chrome bricks, pre-reacted magnesia-chrome bricks Casting magnesia chrome bricks.
The magnesia chrome brick can be used in vulnerable parts of steelmaking electric furnace, RH, DH vacuum degassing device, secondary refining slag line parts such as VOD, LF, ASEA-SKF, AOD, steelmaking converter, cement rotary kiln and glass melting Kiln regenerators, etc.
