Product description

Highlights at a glance

  • It takes good quality fused magnesite and fused mgo-cr clinker as raw material, formed under high pressure,burned in high temperature. It has character of corrosion resistance. Main using for VOD,AOD,SKF,LF,RH etc. secondary refining furnace.
  • High Temperature Resistance
  • The refractory temperature of magnesia-alumina spinel bricks can reach 1650℃ to 1800℃, and they can maintain good structural stability under extremely high temperature conditions.
  • Excellent Thermal Shock Stability
  • Strong Erosion Resistance Magnesia-alumina spinel bricks have excellent resistance to alkaline slag and iron oxide slag, and can effectively protect the brick body from erosion by slag, thereby extending its service life.
  • Low Thermal Conductivity and Good Thermal Insulation Performance This material has a low thermal conductivity coefficient, which helps to improve energy utilization and reduce heat loss, and is suitable for furnace linings.
  • Excellent Physical Properties Magnesia-alumina spinel bricks not only have high strength and good structural flexibility, but also have a low thermal expansion coefficient. These characteristics enable it to maintain a stable shape in a high temperature environment and reduce stress problems caused by thermal expansion.
  • Good Wear Resistance and Anti-scouring Ability Under high temperature and high-speed airflow environment, the brick material shows excellent wear resistance and anti-scouring ability, so that it can maintain a long service life in places such as cement kilns that need to withstand material scouring and wear.
  • Environmental Characteristics The manufacturing process of magnesium-aluminum spinel bricks uses environmentally friendly materials and advanced production processes to reduce environmental pollution. At the same time, its high performance and long life also meet the requirements of sustainable development.
