About Magnesia Carbon Bricks

Magnesia Carbon Bricks

We are supplying the Magnesia Carbon Bricks are un-fired refractory products. Mag-carbon products are designed with improved corrosion and slag resistance through the addition of graphite. When a carbon brick is bonded with an organic resin, it is also known as resin-bonded carbon brick. The brick is a kind of non-burning carbon composite refractory, made from alkaline magnesium oxide and high melting point. The offered Magnesia Carbon Bricks are very easy to use and are made for use in various industries.

Superior Refractory Performance

Magnesia Carbon Bricks offer excellent performance at high temperatures, with maximum operating temperatures reaching 1800C and a melting point of approximately 2800C. Their robust structure, low porosity, and high thermal conductivity make them essential for demanding thermal applications in steel-making and iron-processing industries.

Exceptional Durability and Strength

Engineered with a cold crushing strength of 25-35 MPa and a modulus of rupture between 6-10 MPa, these bricks withstand mechanical and thermal stresses encountered in furnaces and ladles. The use of phenolic resin as a binding agent further contributes to their longevity and reduces water absorption below 0.3%.

Versatile and Customizable Solutions

Available in standard and customizable sizes, Magnesia Carbon Bricks are well-suited for diverse steel industry usage, including ladle linings, converter walls, and EAF roofs. Their high purity, smooth surface, and excellent dimensional stability enable precise installation and extended refractory service life.

FAQ's of Magnesia Carbon Bricks:

Q: How are Magnesia Carbon Bricks used in steel plants?

A: Magnesia Carbon Bricks are primarily used as lining materials in steel-making furnaces, ladles, converters, and electric arc furnace (EAF) walls and roofs. Their excellent thermal shock and oxidation resistance make them ideal for withstanding the rapid temperature changes and corrosive environments found in steel plants.

Q: What benefits do anti-oxidants add to Magnesia Carbon Bricks?

A: Anti-oxidants incorporated into Magnesia Carbon Bricks enhance oxidation resistance, extending brick life during high-temperature operations. They prevent carbon oxidation, thereby maintaining structural integrity and reducing maintenance frequency in aggressive furnace conditions.

Q: When should Magnesia Carbon Bricks be selected for industrial applications?

A: These bricks should be chosen when high-temperature resilience, thermal shock resistance, and low porosity are required. Applications such as steel-making, iron manufacturing, and foundry operations benefit from their dimensional stability and resistance to chemical and thermal attack.

Q: What is the process for installing Magnesia Carbon Bricks in a furnace lining?

A: Installation involves placing the bricks in the designated area, ensuring close alignment for a strong refractory wall. Phenolic resin binding agent is often used to enhance adhesion, and customized sizes allow for optimal fitting in complex furnace designs, improving thermal insulation and performance.

Q: Where can Magnesia Carbon Bricks be sourced or supplied?

A: Magnesia Carbon Bricks are available from exporters, manufacturers, and suppliers in India and globally. Ensuring a reputable supplier guarantees access to bricks with verified chemical composition, mechanical strength, and dimensional accuracy needed for demanding industrial environments.

Q: What makes the bricks suitable for service temperatures up to 1800C?

A: Their high MgO content (over 70%) and carbon levels (10-20%), combined with low porosity and high density, enable the bricks to endure extreme temperatures. This ensures reliable operation and longevity in furnaces operating at up to 1800C.

Q: How does the low porosity of Magnesia Carbon Bricks benefit furnace applications?

A: Low porosity ( 6%) reduces the risk of slag and gas penetration, improving the longevity and efficiency of furnace linings. This enhances the overall structural performance and minimizes downtime caused by refractory wear.
