高铬制品High Chrome Products

    High chrome bricks, characterized by good corrosion resistance and hot mechanicalproperties, are mainly used as the inner lining of the coal water slurrygasifers, petrol coke pressurized gasifiers and working lining of other meltingdevices where acid alkali slag corrosion is serious.

   So far, the high chrome bricks produced by LIRR have been applied in the coalwater slurry gasifiers in more than 30 plants with excellent performance. Theeffective campaign life of the bricks working on the imported coal water slurrygasifiers exceeds 10000 h with the maximum of 23000 h. The bricks were awardedas the Second Prize of Science and Technology Progress by the Ministry of ChemicalIndustry, and the Second Prize of Henan Provincial Science and TechnologyProgress in 1999. The annual capacity of the high chrome bricks is 5000 tons.
