Application:
Blast cleaning of cast steel grit:Used for blast cleaning of
casting, die-casting, forging, sand removal of casting, steel
plate, H type steel, steel structure.
Rust removal of cast steel grit:Rust removal of casting,
forging, steel plate, H type steel, steel structure, descaling
of?forging.
Shot blasting of cast steel grit:Shot blasting of profile
steel, ship board, steel board, steel material.
Shot blasting of cast steel:Shot blasting of steel board,
profile steel, steel structure.
Pre-treatment of cast steel grit:Pre-treatment of surface,
steel board, profile steel, steel structure,
before-painting.
Steel Grit Types:
GP:Angular when new, this grit rapidly rounds off in use and
its particularly suited descaling applications.
GL:Although harder then GP steel grit, also loses its sharp
edges during shto basting and is particularly suited to
descaling and surface preparation applications.
GH:Having maximum hardness, GH always remains angular in its
operating mix. These abrasive are particularly effective in
surface treatment processes and produce a uniform, etched
finish, GH angular grit should only be used in wheel machines
where working requirements take precedence over cost price
considerations (for example with rolling mill cylinders or when
a special finish is needed). For use mainly with compressed air
equipment.
