碳化硅质泡沫陶瓷的用途 熔融金属过滤的 泡沫陶瓷 过滤片 铸铁件生产的特点,提出铸铁对泡沫陶瓷过滤材料性能的要求。较详细地介绍了研制铸铁用碳化硅泡沫陶瓷过滤材料方面所做的工作。以较充实的试验结果证明所研制的碳化硅泡沫陶瓷过滤铸铁液效果良好,并对泡沫陶瓷过滤的机理进行了合理的分析 泡沫陶瓷过滤材料具有强度高、孔隙率大、流体易于通过、耐高温、化学上稳定等特点,因此具有广泛的用途。本项目研制的SiC质泡沫陶瓷过滤片是用于哈尔滨东安发动机制造公司新近从德国、美国、西班牙引进的自动化铸造生产***,该生产线生产的4I缸盖、缸体和491Q缸体是为北京切诺基和丰田4Y系列车配套的,经过一年多时间四万余件缸体生产上的使用实验,表明SiC质泡沫陶瓷过滤片能够满足铸件的过滤净化要求,能够去除夹杂,改善金相组织结构,显著提高铸件的机械性能。 化学成分:SiC 50-90%,其它 50-10% 物理性能: 容重:0.4-0.7g/cm3 孔隙率:70-80% 常温耐压强度:1.65mpa 耐火度:1600ºC 热震稳定性:(1100-水冷)6次 吸水率:<1% GUIZHOU NEW MATERIALS MINERAL DEVELOPMENT CO., LTD, we make the ceramic foam filter are the reticulated ceramic structure. Applications of ceramic foam filter: THE RETICULATED CERAMIC STRUCTURES OF GZNM CERAMIC FOAM FILTER MAKE THEM IDEAL FOR A MAJORITY OF CASTING AND NONFERROUS ALLOY APPLICATIONS, AND THERMAL STABILITY AND THERMAL SHOCK RESSISTANCE ALSO, MAKE THEM PARTICULARLY FIT FOR STEEL CAST. Specification of ceramic foam filters: RECTANGLE: 50x50x20; 75x75x15;75x75x20; 100x100x20 (mm) Round (diameter ): diam.40x15; 50x20; 60x20 (mm),and so on. Range of Mesh : 8ppi to 45ppi TYPE OF CERAMIC FOAM FILTERS: 1. SILICON CARBIDE CERAMIC FOAM FILTERS: UNIT POROSITY (percentage): 80 to 90 DENSITY (g per cm3): 1.0 Approximate use temperature (Degree Centigrade): 1500. Normal temperature bending strength (Mpa): 0.8 to 1.0 Mpa Thermal shock resistance (in 1110 degree centigrade ): above 6 times 2. ZIRCONIUM OXIDE CERAMIC FOAM FILTERS UNIT POROSITY(percentage ): 80 90 DENSITY (g per cm3): 1.0 Approximate use temperature (degree centigrade): 1700 degree centigrade. Normal temperature bending strength (Mpa): 0.8 to 1.0 Mpa Thermal shock resistance (in 1110 degree centigrade): above 7 time WE CAN DESIGNS AND MANUFACTURES THE CERAMIC FILTER ACCORDING TO OUR CUSTOMER`S REQUIREMENT OF CASTING AND POURING.
