Description
conditioned steel cut wire shot implements the steel wire cut shot standard—JB/T8354-1996, which has the advantages of steel wire cut shot, and also has the following characteristics:
1. Appearance
conditioned steel cut wire shotshould be oval, and the number of ultra-long and flat flake particles in the finished product should not exceed 10% of the inspected amount;
2. Specifications
The specification range of conditioned steel cut wire shot is 0.3mm, 0.4mm 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.7mm, 1.8mm, 2.0mm, 2.4mm.
3. Technical requirements
The chemical composition and content of the abrasive pellets shall meet the following requirements:
chemical composition
C :0.65-1.10
Si:0.8-1.65
Mn:1.20-2.0
P:<0.05
S:<0.05
4. Hardness
HRC of conditioned steel cut wire shot: 50-65 (not tempered) HRC: 40-50 (tempered)
5. Metallographic organization
The metallographic structure of theconditioned steel cut wire shot is tempered martensite, tempered troostite
6. Cracks
conditioned steel cut wire shot with cracks shall not exceed 3% of the inspected amount
7. Physical properties
The willfulness of the conditioned steel cut wire shot is I, and the tensile strength is 1520N/m㎡
Eight, one, cycle life
The cycle life of conditioned steel cut wire shot is more than 3 times that of cast steel shot and wire cut shot.
To sum up, the conditioned steel cut wire shot has obvious advantages over other products in terms of manufacturing and selection of raw materials. It has the characteristics of high manganese steel. At the same time, the conditioned steel shot has no holes, no cracks, and the hardness of the conditioned shot is balanced. In comparison, other products such as steel wire cut shot and cast steel shot have poor toughness, short life, high cost and relatively small scope of application; the above advantages are sufficient to show that grinding steel shot is much stronger than other projectile products.
Finally, when it comes to cost performance, the same performance versus quality, the same quality versus price, superior quality, and superior price, under the same conditions, the ultimate purpose of using the product is to achieve the best surface cleaning, and the national standards for cast steel shot allow There are defects such as pores, cracks, and short service life. The steel wire cut shot has no leading angle, has edges and corners, and runs on a track, which causes great damage to the equipment and workpiece, and is highly destructive, thus increasing the cost; while the grinding shot overcomes the above two. All the weaknesses of this product, no pores, no cracks, its life is 2.5 times that of cast steel shot.
In short, to achieve the best surface cleaning results, conditioned steel cut wire shot is the first choice.
