Advantages of steel shots with cut wire steel shots |
STEEL SHOTS (balls) |
CUT WIRE STEEL SHOTS |
For
steel shots, raw material is steel scrap of unknown
approximate comparison |
Wire
rod in steel mill is made from exact composition |
Lot of
melting 5-10 tons max. |
200 to
500 ton melt for wire rod mill for making 6 ml. Rod |
Grain
size of cast shots 1-5 |
Due to
eight rolling passes grain size 7.9. |
Blow
Holes & Trails |
No Blow
Holes & Trails |
Shots
produced are of mixed size hence product is a mix.
Of various spherical sizes |
All
shots being out of same wire are identical |
As
quenching of steel globules is from 1600’c shrinkage
and porosity unavailable. Hence density max. 7 |
No
porosity-shrinkage hence 7.85 |
Material remove by impact only |
Cylindrical edges scrape material faster |
Shots
break in to dust |
SHOTS ONLY WEAR DOWN |
Abrasive dust produced from shots increase shot
blasting machine maintenances |
Lower
maintenances of machine due to absence of ABRASIVE
DUST |
Steel
dust also in dept’s atmosphere |
No
steel shot dust Generated |
