Filtration Media

short description:

Spherical balls of alpha-alumina (corundum) is produced by sintering ball-formed calcined alumina at a temperature just under the 3704°F (2040°C) fusion point of aluminum oxide. These tabular alumina balls are then crushed, graded or screened, and ground to a wide range of granule. The powder size must be controlled in good condition, meanwhile adding special film formation additive . Otherwise, the corundum gravel can not absorb the particle from liquid metal。 There are four kinds of filtration media: . 1XXX,3XXX,8XXX;2XXX,7XXX;5XXX,6XXX;High purity aluminium. The Film formation additive is different.

Application:

Deep bed molten aluminum or steel filtration.

Properties:

Spherical balls of alpha-alumina (corundum) is produced by sintering ball-formed calcined alumina at a temperature just under the 3704°F (2040°C) fusion point of aluminum oxide.

These tabular alumina balls are then crushed, graded or screened, and ground to a wide range of granule. The powder size must be controlled in good condition, meanwhile adding special film formation additive .

Otherwise, the corundum gravel can not absorb the particle from liquid metal。 There are four kinds of filtration media: . 1XXX,3XXX,8XXX;2XXX,7XXX;5XXX,6XXX;High purity aluminium. The Film formation additive is different.

Material Characteristics:

Inert to molten aluminum Dust Free。 Does not leach soda upon immersion in molten aluminum Sphere or ball shape should be uniform.

Advantages:

Good resistance to thermal and mechanical shock; Excellent abrasion resistance

Appearance:

White crystalline gravel or ball. Depending on requirements, ball sizes are produced from 1/8 to 2 inch (tolerance ± 6% mm); Gravel size: 1-18mm
