电熔锆刚玉材料电熔锆刚玉产品一般通过长弧熔融和氧化法处理进行生产，产品按照氧化锆的含量和浇铸方法分类Electro-fused zirconia-corundum refractory brick电熔锆刚玉耐火砖NH（耐火）NH-33：Material is electro-fused alumina-zirconia-silica, with 33% ZrO2Chemical composition:Al2O350.45%ZrO233%SiO215% Na2O(以碳酸钠的形式加入)、B2O 熔剂1.3% TiO2、Fe2O3 0.25%在此基础上采用部分脱硅锆英石砂作原料即可制成41#的砖Crystallographic analysis:Alumina (corundum) 46.5%Zirconia 32.5%Vitreous phase 21%True specific gravity(真比重): 3840kg/m3Cold crushing strength (冷抗压强度)200MpaRefractoriness under load(荷重软化点) 1700°CNH-33PTIntroduction:The unique technology of DY changes distribution of shrinkage voids of regular casting bricks, reducing shrinkage voids, and increases the dependability of bricks.Recommendations:Superstructure, working end and Feeder channel, etc.Shaped block:Due to the material’s excellent castability, this product can be made into kinds of different shapes and sizes such as Feeder channel block、thermocouple block、tuck stone、crown、burner block.NH-33ZWSIntroduction:The remained voids are small and located at bottom of the brick, which should be down when the brick of this type is in use.(残存缩孔很小集中在尾端，使用时尾端朝下)Recommendations:This product is designed for the sidewalls of Flame Furnaces with embedded melted bottoms, for total, security with average pulls and campaign lengths.（本品种适用于火焰窑之池壁，池底为嵌固式，出料量、窑期中等）Shape and size:This product is only available for straight brick or approximate ones.NH-33WS：Introduction:Dense casting bricks are cast from exclusive riser, which assures the melted liquid cast into the model almostly. (本产品配置专用冒口浇铸，可保证浇铸溶液最大限度的注入砂型中，所得浇铸砖致密)Recommendations:This product is designed for the special places of Flame Furnace, such as side wall, tank bottom, superstructure, feeder channel, bowl, bleeder, C shaped brick, etc.(本品种适用于火焰窑之池壁、池底、上部结构，料道及料盆，搅拌浆，C型砖等特殊部位。Shape and size:Various of straight bricks and shaped bricks can be produced by different casting and processing ways.NH-36:Introduction:Material is electro-fused Alumina-zirconnia-sili
