3.15
blast hoseblast tube
hose or tube connecting a nozzle to the blast pot (3.17)3.16
blast nozzle
component connected at the outlet of the blast gun (3.14) with the desired shape, size and abrasiveresistance which determines the abrasive media (3.4) flow and angle
3.17
blast pot
blast hopper
container of air blaster ([3.8) for storing abrasive media [3.4)3.18
blasting angle
angle between the centre line of the abrasive beam ejected from the nozzle and the surface of theworkpiece being blasted during abrasive blasting (3.1)
3.19
blasting chamber
chamber of abrasive blasting machine (3.2) which contains the workpiece and also prevents the abrasivemedia[3.4) from escaping to the environment after impacting on the workpiece
3.20
blasting density
amount of abrasive media (3.4) blasted per unit area within the surface that has been impacted by theabrasive media([3.4)
3.21
blasting distance
distance between the nozzle and the surface of workpiece to be blasted during abrasive blasting (3.1)3.22
blasting pattern
effective area of workpiece surface covered by abrasive beam blasted by wheel blaster (3.86)3.23
blasting pressure
working pressure of compressed air fed into nozzle or in blast pot (3.17) during compressed-air abrasiveblasting (3.29)
3.24
bogie decoring machine
decoring machine (3.36) that uses bogie to transport workpieces3.25
bucket elevator
continuous conveyor that uses a series of bucket shaped hoppers uniformly fixed on the endless circulartraction component to vertically lift abrasive media (3.4), foundry sand and impurities
3.26
carbon-arc-gouging torch
device for purging molten metal and oxides with compressed air while melting flash and burr by archeat generated between graphite rod or carbon rod and castings
3.27
casting cooling and transferring system
system used for recooling of casting after demolding
Note 1 to entry: It uses continuous conveyor, such as vibrating conveyor or overhead chain conveyor, and can beequipped with ventilating and spray cooling system.

3.28
centrifugal abrasive blastingwheel blasting
abrasive blasting ([3.1) using wheel blasting machine (3.87)3.29
compressed-air abrasive blastingair blasting
abrasive blasting([3.1] using air blasting machine[3.9)
Note 1 to entry:The abrasive media (3.4) may be injected into the air stream from a pressurized container or maybe drawn into the air stream by suction from an unpressurized container.
3.30
continuous grind fettling machine
grind fettling machine (3.46) with automatic workpiece conveying and clamping mechanism which iscapable of continuous grinding operation
3.31
conveyor type blasting machine
abrasive blasting machine (3.2) that uses conveyor to carry the workpiece into and out of the blastingchamber[3.19)
Note 1 to entry:The machines are further differentiated by conveyor type, i.e.rollers, rubber belt, wire mesh.chain.
3.32
coverage
percentage of a surface that has been impacted by abrasive media(3.4) to the surface area required fortreatment
3.33
deburring
removal of flashes and burrs from castings3.34
decoring
core knock-out
process in which sand core is removed from the inner cavity of the casting by hammering or any otherway
[SOURCE: ISO 23472-1:2020,3.38]
3.35
decoring cell
complete set of decoring (3.34) equipment that consists of a decoring machine(3.36), a robot for loadingand unloading workpieces, an exhaust system, etc.
[SOURCE: ISO 23472-1:2020,3.39]
3.36
decoring machine
machine that removes the sand core from the inner cavity of the casting by pneumatic or hydraulicimpact hammer (3.52)
Note 1 to entry: It is usually composed of a hammering mechanism, a conveying mechanism for workpiece and achamber which prevents dust from escaping.Among them, the conveying of the workpiece can adopt motorizedroller(s), mobile car(s), turntable(s), manipulator(s) or robot(s).

derusting
removal of rust on the surface of castings3.39
descaling
removal of oxide scale on the surface of castings3.40
direct pressurized air blaster
one type of air blaster (3.8) that injects compressed air in the blast pot(3.17) to transport the abrasivemedia (3.4) to the blast gun (3.14)
3.41
electro-hydraulic cleaning device
complete set of devices used to remove adhering sand on the surface of castings and sand core in theinner cavity of castings by means of electro-hydraulic cleaning process.ISO 23472-4 pdf download.
