What is magnesia carbon brick?

magnesia carbon brick, often referred to as magnesia-carbon bricks, are a type of refractory brick that combines magnesia (MgO) with carbon (usually in the form of graphite). These bricks are specifically designed to withstand extreme temperatures and harsh chemical environments, making them ideal for use in the steelmaking industry and other high-temperature applications.

LMM GROUP top-grade magnesia carbon brick are produced using advanced techniques, guaranteeing exceptional strength and longevity.

Where are magnesia carbon bricks applied?

Magnesia carbon bricks are widely used in the following fields:

Iron and steel industry: used for linings of steelmaking converters, electric furnaces and ladles, with good thermal shock resistance and slag erosion resistance.
Non-ferrous metal smelting: used for high-temperature furnace linings in the smelting process of non-ferrous metals such as copper and aluminum.
Cement kiln: In the rotary kiln of cement production, magnesia carbon bricks can be used for the lining of the high-temperature firing zone.
Glass kiln: In the glass melting furnace, it is used for the lining of the high-temperature area to increase the service life of the kiln.
Other high-temperature industries: such as lining materials for high-temperature furnaces such as petrochemicals and waste incineration.

How to choose magnesia carbon bricks?

Material composition: Select high-purity magnesia sand and high-quality carbon materials to ensure that magnesia carbon bricks have excellent refractory properties and slag erosion resistance.

Thermal shock resistance: According to the temperature fluctuations in the use environment, select magnesia carbon bricks with good thermal shock resistance to avoid cracking and peeling of the brick body.

Size and shape: Select the appropriate size and shape of magnesia carbon bricks according to specific application requirements to ensure the best installation and use effect.

Manufacturing process: Select manufacturers with advanced manufacturing processes to ensure that the density and strength of magnesia carbon bricks meet the requirements and extend the service life.

Wear resistance: In a high-wear environment, select magnesia carbon bricks with high wear resistance to extend the service life of the brick body.

Price and service: Consider the cost-effectiveness and select suppliers with good after-sales service to ensure that problems encountered during use can be solved in time.
