The difference between steel shot and steel wire cutting shot. S460 and CW1.5 have different roughness and durability

Description :

　　As the name suggests, steel wire pellets are made from steel wire rope or raw silk, cut into sections. The model refers to the diameter of the steel wire pellets, not the length of the cut. This type of production is relatively simple and cost-effective, so the price is also relatively cheap. The advantage of cutting silk and pellets is that they are cheap and have a long service life, but the roughness of the cleaned workpiece is relatively high, which is not suitable for processing high-precision workpieces.

　　Cast steel pellets are first and foremost pellets, which are spherical in shape. Their production process is relatively complex and the cost is also relatively high. Cast steel pellets are more expensive and have a shorter service life than steel wire pellets, but they can only be used for workpieces with smooth surfaces and high surface roughness requirements.

　　1. The shape of steel balls is spherical, with fewer physical defects and a defect free internal structure, making them more resistant to impact. Steel wire pellets are cut from raw or ripe silk and are cylindrical in shape. The shape of steel wire pellets is irregular, with varying lengths and irregular cuts.

　　2. The roundness of the steel shot is good, and after the spherical impact, the point of force on the workpiece is regular, the force is uniform, and the hardness is moderate, so the rebound elasticity is better. The shape of the steel wire cutting ball is irregular, and the point of application is also irregular, resulting in uneven force distribution and poor rebound performance. Due to its spherical shape, the wear of steel shot is gradual, and a good proportion of mixed particles of different sizes will be formed during use. The coverage of steel shot is good, and the efficiency of shot blasting cleaning is higher. Steel wire shot blasting is irregular in shape, with minimal wear in the early stages, but later it will burst into powder, unable to form a suitable proportion of mixed particles of different sizes. Therefore, the coverage rate of shot blasting is low, and the cleaning efficiency is not as high as that of steel shot blasting. Practice has proven that the cleaning efficiency of steel shot is 20% higher than that of steel wire cutting shot.

　　3. The poor fluidity of steel wire cutting pellets in the cleaning equipment results in uneven stress on the head of the shot blasting machine, causing increased wear and tear on the equipment. The service life of wear-resistant parts using steel shot as abrasive is more than four times that of steel wire cutting shot, which reduces the maintenance cost of shot blasting equipment and prolongs the overall service life of the machine.

　　4. The surface of the workpiece cleaned with steel shot is delicate and shiny, with good surface quality, providing the grade of the workpiece. Due to the irregular and angular shape of the steel wire cutting ball, the force applied to the workpiece at each angle is different, resulting in a rough and uneven surface of the workpiece.

　　In practical production, the two can be mixed together to complement each other's strengths and weaknesses, achieving a better combination. Steel wire cutting balls have a long service life and are inexpensive, and can handle workpieces with high roughness. Cast steel shot has a short service life, high price, and smooth processing of workpieces
