Features: Special Mg-chrome bricks is directly combined by high purity fused magnesia clinker and high purity chromium concentrate and high-temperature composite toughening agents, the high-pressure forming, high temperature sintering made a performance special excellent product, it not only good erosion resistance performance is good, and thermal shock resistance than mg-chrome bricks directly combined much better, this product has good solve erosion resistance performance and thermal shock resistance can’t sync contradiction.
