Magnesia Carbon Brick

Using Magnesia Carbon Brick as a component in your refractory system, will give you a good resistance to thermal shock. In addition to its great resistance to thermal shock, Magnesia Carbon Brick also has excellent resistance to slag and corrosion.

Magnesia carbon bricks are a type of refractory brick that is composed of high melting point carbon materials. It is commonly used in electric furnace lining, in tapholes, and in furnace caps. The material is mainly made from a blend of high purity fused magnesia and carbon. The chemistry of the material is controlled in order to produce an ideal brick.

The material is formed through a process that involves a high pressure molding process. The phenolic resin is heated to a temperature of 35-45 C. During the process, the average molecular weight of the resin is reduced. This is the basis for the lamination phenomenon in the material. Generally, the more phenol resin is used, the more lamination happens. However, in this invention, novolak phenol resin is used in a quantity of two to six percent by weight.

The additives used in MgO-C brick include silicon, aluminum, magnesium-boron, and titanium oxide. These additives react with the carbon to change the microstructure of the material. They also increase the strength of the brick. Some of the additives are used to replace tars, while others are used to enhance the strength of the brick.

The raw materials used in the production of Magnesia Carbon Brick are sintered magnesia, high purity graphite, and carbon. In addition to the raw materials, a phenolic resin is used as the binder. These additives are mixed together before the final product is cured. It is important to have the right blend of additives and to cure the material properly, in order to get the desired results. Incorrect curing can result in deterioration of the microstructure, shrinkage of the matrix, or expansion of the particle in use. The time required to cure the material will vary. This can impact the service life and bonding strength of the brick.

Magnesia carbon bricks have been developed to overcome the drawbacks of a magnesium brick, such as a poor spalling resistance. The use of improved grains has increased the production of bricks with better physical properties. The use of improved grains has also contributed to better slag resistance in the bricks. It also helps to improve the coexistence of magnesia and graphite at high temperatures.

Magnesia carbon bricks can be used for lining steel in tough conditions. They are also used in the bottom of continuous casting tundish and in refining packages outside of furnaces. They are also used in molten steel bath. They are also used in the lining of converters and in tapholes. It is important to select the right raw materials for the production of the bricks in order to get a product that is highly resistant to thermal shock.

The market for Magnesia Carbon Bricks is growing rapidly. Some of the drivers for the growth of the market include the use of phosphoric acid storage tanks, stainless steel pickling plants, and sulphuria acid dilution tanks. The oxidation resistance and good resistance to thermal shock of Magnesia Carbon Bricks are also contributing to the growth of the market.
