Description
Fused semi-rebonded magnesia-chrome bricks are made from fused magnesia-chrome spinel, high-purity magnesia, high-purity chrome concentrate, and a composite high-temperature toughening agent. They are formed under high pressure and sintered at high temperature. These bricks exhibit excellent high-temperature performance and thermal stability, high mechanical strength, superior corrosion resistance, and outstanding anti-spalling performance.
Product Size: We offer refractory brick sizes that comply with ISO, EN, ASTM, JIS, etc, and customized sizes.
