鑄造專用白剛玉粉 White Fused Alumina Microgrits for Casting
酬誠礦業生產的精鑄用高純度白剛玉砂粉利用先進的生產設備和特殊工藝，具有雜質小、氣孔率低、體積穩定性和抗熱震性好等特點，可代替鋯英砂粉的熔模鑄造的制殼材料，也用于硅溶膠工藝、大型鑄鋼件,特別是合金鑄件型、芯面砂、涂料等。
The white fused alumina microgrits casting with high purity produced by Choucheng Mining is adopted with advanced production equipment and special technology, with small impurities, low stomatal rate, volume stability and good thermal shock resistance. It can replace casting shell materials made of zirconium grits, but also be used in silica sol technology, large-scale steel castings, especially alloy castings, core sand, coatings and so on.
