Magnesia-Carbon Brick
Magnesia-carbon brick is a refractory brick made of magnesia and a carbon-containing material. Magnesia-carbon brick is known for its proper use of ore as raw material, its high mechanical strength, and its excellent high temperature performance. It is a main material used to build basic carbon furnaces and has been widely used in a variety of industries across the world.
The production of magnesia-carbon bricks mainly involves calcining initial raw materials, forming, pressurizing in a self-hardening water-green brick, and firing in the kiln. The difference between the two types of brick involves the difference in the raw materials and the pre-fired or sintered process.
The percentage of the carbon component in magnesia-carbon brick directly affects the porosity of the brick and the maximum possible temperature that the brick can withstand. The higher the percentage of the carbon component, the lower the porosity and the higher the temperature. For example, some carbon-containing bricks can withstand temperatures of up to 1800o C, whereas some magnesia-containing bricks can only withstand temperatures of up to 1600o C. This is due to the fact that magnesia-containing bricks have higher thermal resistance, but lower carbon content, which contributes to their limitations in temperature resistance.
Magnesia-carbon brick has several advantages, it is ideal for use in industries that require basic carbon furnaces, due to its high heat resistance, low thermal conductivity and low embrittlement at high temperature. Whats more, magnesia-carbon brick also has good thermal shock resistance and wear resistance, making it suitable for applications where thermal shock and wearing refractories are often present.
As magnesia-carbon brick is both non-expansive and diffusion resistant, it makes an ideal material for linings and ladle wells, which require non-expansive and diffusion resistant refractories. Backgrounds and walls may also require this material, as the bricks can withstand temperatures of up to 1800o C.
Magnesia-carbon brick is a highly versatile material and has several different applications, including the construction of masonry and fire protection walls, and for use in ceramic kilns and glass furnaces. It is also used in a variety of industries, including chemical and petrochemical, iron and steel, and aluminum and foundry production.
Magnesia-carbon brick is an essential refractory material and is a main component used in the construction of basic carbon furnaces. Its high temperature resistance and wear resistance make it perfect for a wide variety of applications. As a result, magnesia-carbon brick is an essential component of production and manufacturing processes in a wide range of industries.
