Reasons for the mixed use of steel shot and steel sand and the criteria for judging the quality

　　Although shot blasting and sand blasting can both serve the purpose of cleaning and decontamination, shot blasting can strengthen the workpiece, but sand blasting is not so obvious. Sand and steel shot are used for grinding, derusting and surface treatment of castings; The shot is round, and the steel grit has edges and corners; the steel grit is broken by the steel shot, and the size of the steel grit is also divided into different models according to the size of the steel shot; for different castings, the product models used are also different. Depends on the piece; the hardness of the steel grit is moderate, with excellent resilience, and the casting is cleaned.

　　A better way to clean castings is to mix steel shot and steel grit, so that the steel grit can be thrown to the corners, and the steel shot can be thrown to flatten the surface, which also avoids the roughness of the casting surface. Mixed use will be much better than using a single shot blasting machine abrasive. However, this method is not suitable for every product. It depends on the workpiece and the final shot blasting effect.

　　Steel shots are often used in the treatment of metal surfaces, and the products treated with steel grit can make the products meet the national standards. For now, steel grit is a more advanced and ideal high-quality material for cleaning, blasting, derusting and strengthening at home and abroad.

　　High-quality steel grit products have moderate hardness, strong toughness, and impact resistance. They can be used repeatedly several times in a row. They also have long life, good resilience, strong adhesion, fast cleaning speed, low sand consumption, no breakage, and high brightness of the cleaned workpiece. Good technical effect and many other characteristics.
