Products Description

Refractory magnesia carbon bricks are made from high-purity magnesium oxide and high-quality artificial graphite powder through production processes such as crushing, mixing, pressing, baking, and high-temperature graphitization and purification. The magnesium oxide content is between 85% and 90%, and the graphite content is between 10% and 15%. Since magnesium oxide is an oxide with a high melting point, it can withstand the corrosion of high-temperature molten metal and high-temperature gas. Graphite has good thermal conductivity and thermal shock stability, and can withstand thermal shock loads and cyclic thermal shock loads at high temperatures.

Magnesia carbon bricks have good comprehensive properties. After many actual factory tests, the maximum heat-resistant temperature can reach 2500°C, and its fire resistance is 3 to 5 times that of ordinary graphite materials.

Products Advantages

1. Good fire resistance

Magnesia carbon bricks have good fire resistance and can maintain stable chemical properties in high temperature environments. Its refractory temperature can reach over 2000°C and is suitable for use in various equipment and processes at high temperatures.

2. Good thermal conductivity

Magnesia carbon bricks have good thermal conductivity and can quickly conduct heat and prevent thermal stress. This property is one of the more important properties at high temperatures.

3. Good thermal shock stability

The graphite component of magnesia carbon bricks can increase its thermal shock stability. It is not prone to brittle fracture under thermal shock loads at high temperatures and can also withstand cyclic thermal shock loads well.

4. Good corrosion resistance

Magnesia carbon bricks have good resistance to erosion by molten metal and high-temperature gases. Magnesia carbon bricks can be considered as refractory bricks in metal furnaces and high-temperature environments, which have better results.

Products Applications

1. Metal furnace

Metal furnaces are one of the main application areas of magnesia carbon bricks. In the process of metal refining and smelting, the furnace body needs to withstand high temperatures and molten metal corrosion for a long time. The use of magnesia carbon bricks can effectively extend the life of the furnace body.

2. Electric arc furnace

Electric arc furnace is a high-temperature equipment used for smelting various metals, lithium batteries and other industrial purposes. Magnesia-carbon bricks are the core part of the electric arc furnace. Due to different types and quantities, they can be customized according to different usage situations.

3. Silicon furnace

The silicon furnace is a special high-temperature equipment whose operating temperature can reach over 1400°C. Magnesia carbon bricks play an important role in silicon furnaces and can effectively prevent silicon furnace penetration and thermal stress.
