magnesia carbon brick
Magnesia carbon brick represents a crucial advancement in refractory technology, combining the superior properties of magnesia with the enhanced thermal and chemical resistance of carbon. This innovative composite material consists of high-purity magnesia clinker and carefully selected carbon sources, typically high-quality graphite flakes. The brick's composition typically ranges from 8% to 20% carbon content, making it exceptionally resistant to thermal shock and slag penetration. The manufacturing process involves sophisticated mixing techniques, high-pressure forming, and specialized tempering procedures that ensure optimal bonding between the magnesia and carbon components. These bricks excel in environments requiring exceptional thermal stability, with the ability to withstand temperatures exceeding 1700°C while maintaining structural integrity. The carbon content creates a non-wetting surface that significantly reduces slag penetration, while the magnesia provides excellent refractoriness and basic slag resistance. In steel manufacturing, these bricks are particularly valuable in basic oxygen furnaces, electric arc furnaces, and steel ladles, where they face extreme thermal cycling and aggressive chemical environments. The unique combination of materials also results in improved thermal conductivity and reduced thermal expansion, contributing to extended service life and reduced maintenance requirements in industrial applications.
