It is a kind of refractory sand for casting, which is made of high Alumina Calcined Bauxite. Produced through fusing, spraying, sieving, getting rid of impurity, we gain the top grade casting sand. As the shape is globose, it has excellent fluidity and filling character.
It can be used in big, middle and small steel casting parts extensively. It is suitable for various bonds of casting mould, therefore the usage is widely. It also has an advantage at the regeneration of casting sand. Repeated use of ceramic beads can reduce casting cost much more.
