Description of magnesia carbon bricks

Magnesia carbon brick is a non-combustible carbon composite refractory material made of magnesium oxide (melting point 2800 ℃) and carbon materials with high melting point as raw materials, with the addition of various non-oxide additives and combined with carbon binders. The presence of carbon increases the slag resistance of periclase (magnesite) refractories in their service by an order of magnitude, because carbon prevents slag melt from entering this product.

Advantages of magnesia carbon bricks

Excellent heat resistance

Magnesia carbon bricks have excellent characteristics at high temperatures and can be used for long periods of time at temperatures above 1200 °C.

Good resistance to thermal shock

Magnesia carbon bricks have very good thermal shock characteristics at high temperatures and can withstand large temperature variations without cracking.

Good corrosion resistance

Magnesia carbon bricks have excellent corrosion resistance to slag erosion, so they can be used in strong corrosive environments such as acids and alkalis.

Good thermal conductivity

Magnesia carbon bricks have good thermal conductivity, capable of evenly distributing and transferring heat, which helps to improve production efficiency.

Application of periclase-carbon bricks

Ferrous metallurgy

In iron and steel industry, magnesia carbon bricks are mainly used for internal lining of high-temperature melting furnaces such as ladle, converter, electric furnace and all kinds of slag mouths, jams, coke nozzles, ladle lids and other parts.

Glass industry

Magnesia carbon bricks are widely used in the glass industry, mainly in glass furnaces for lining sidewalls, vaults and bottoms. They are able to withstand the high temperatures and harsh chemical conditions of the glass production process.

Other industries

In addition, magnesia carbon bricks are also widely used in petroleum, metallurgy, electricity and other industries in the field of high-temperature melting furnaces, electric furnaces, portal and railroad locomotives and other parts.

Non-ferrous metallurgy

Magnesia carbon bricks are widely used in the cement industry, in the combustion and transition zones of cement kilns and rotary kilns due to their ability to withstand high temperatures and chemical environments.

Cement industry

Magnesia carbon bricks are widely used in the cement industry and are used in the combustion and transition zone of cement kilns and rotary kilns due to their ability to withstand high temperatures and chemical attack.

Chemical industry

In the chemical industry, magnesia carbon bricks are widely used for internal lining, gas baffle and lining of various high temperature reactors, reformers and cracking furnaces.
