Magnesite carbon brick

Introduction:

Magnesite carbon brick is a refractory product made of magnesite and graphite as main raw materials. Magnesium oxide and carbon are its main components, and they have high fire resistance. MgO and C are not eutectic and do not form low melting point substances. The thermal conductivity of graphite makes the magnesite carbon brick have good thermal shock resistance. The non-wetting effect of graphite on molten steel and slag can prevent the slag from penetrating, and the anti-flaking and slag resistance are better. However, magnesite carbon bricks are easily oxidized by heating in air, and can be improved by adding antioxidants. Generally magnesite carbon bricks are non-fired products, and the production process is same as other non-fired refractory products. The heat treatment is generally carried out at 150-200 ° C for a period of not less than 32 h.

Advantages:

Magnesite carbon brick has the characteristics of high temperature resistance, strong slag resistance, good thermal shock resistance and high temperature strength.

Application:

Magnesite carbon bricks are mainly used in converter lining and bottom gas supply components, electric furnace hot spots and lining, steel ladle, refining furnaces, etc. In order to balance the furnace lining, magnesite carbon bricks gradually develop to a variety of varieties.
