Riser Sleeve is used as the material of tap-out cone which is for aluminum melting reverberatory furnace. It can also be used as the material of riser sleeves in aluminum casting which needed high insulating environment.

Both IN-200 and IN-300 are used as the material of riser sleeves in application of ferrous and non-ferrous casting. 

ADVANTAGES

Ø  High insulating function

Ø  No flammable

Ø  Less porosity production during casting proces
