Magnesite Bricks Description

Magnesite Bricks are produced with more than 90% magnesium oxide content as the raw material and periclase as the principal crystalline phase after smashing, mulling, molding, firing and drying in the high temperature. Magnesite Bricks can be classified into two types of burnt magnesite bricks and unburnt magnesite bricks.

Magnesite Bricks Properties

• High refractoriness
• Good alkali slag property
• High refractoriness under load initial temperature

Magnesite Bricks Uses

Magnesite Bricks are mainly used in basic open-hearth furnace for steel-making, bottom and wall of electric furnace, perpetual lining of oxygen converter, non-ferrous metal metallurgy furnace, high temperature tunnel kiln, lining of rotary kiln for firing magnesite bricks and cement, bottom and wall of heating furnace, regenerative chamber checkerwork of glass furnace.

Magnesite Bricks Manufacturing Process

Burnt Magnesite Bricks are manufactured with magnesite as the raw material after smashing, burdening, mulling and molding through firing in the high temperature of 1550~1600℃. High purity products’ firing temperature is over 1750℃. Unburnt Magnesite Bricks are added into suitable chemical binding agent through mulling, molding and drying.
