Production Process of Ceramic Sand
Raw aluminum cores contains lots of free water, crystal water, and low melting point components. Using raw aluminum cores to produce consumes large amount of electric energy and it is difficult to eliminate low melting point components, causing the instability of the product and affecting product quality. So it is important and essential to calcine the raw aluminum cores and use wrought aluminum cores (so called bauxite) as main material
