砂型铸件用金砂

简短的介绍：

铸造陶瓷砂，专业名称为“铸造用烧结陶瓷砂”，也称为陶粒、陶瓷铸模，与陶瓷珠相同，一些国家也将其称为金砂，是一种由煅烧铝土矿制成的优质人造球形颗粒。其主要成分是氧化铝和氧化硅。陶瓷砂的性能比硅砂好得多，可在铸造中获得更好的性能。它具有高耐火度、小热膨胀、良好的角系数、优异的流动性、高耐磨性、抗压性和抗热震性，回收率高。

产品标签

Foundry Ceramic Sand, technically named as “Sintered Ceramic Sand for Foundry”, also named as ceramsite, cerabeads, ceramcast, some countries is also named Golden Sand, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

优势

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.

应用

KAIST陶砂作为中性材料，适用于酸碱树脂。

可广泛应用于铸铁、铸钢及有色金属铸造，如消失模铸造、覆膜砂、树脂砂、冷芯盒、精密铸造、3D打印等。
