Many users will ask us this question, do alloy steel balls need to be smelted? It's actually not necessary. Why? Because it is a product formed after quenching, there is no need for re smelting. This smelting process is actually a series of chemical reactions that control the content of impurity elements within a certain range. This process is meaningless for alloy steel shot, so it is unnecessary. Now, let's take a closer look.
Alloy steel shot is made by directly quenching forged bearing steel and crushing it into steel shot alloy. There is no smelting process or casting defects in the manufacturing process. It is an energy-saving and pollution-free product. The traditional steel shot follows the process of "making sand first and then making shot", which requires smelting and has many casting defects. It is an alloy steel shot with high energy consumption and high pollution in the manufacturing process.
Moderate hardness, strong toughness, impact resistance, and can be used continuously and repeatedly. Long service life, good rebound, strong adhesion, fast cleaning speed, low sand consumption, no damage, high brightness of the workpiece after cleaning, and good technical effect. The cleanliness of the processed metal surface meets international standards. The surface roughness of alloy steel shot reaches 25-100m, which increases the contact area of the metal surface, improves the adhesion of the coating surface, and has significant economic benefits for refining the metal surface and strengthening the metal structure. It is currently an advanced and ideal material for cleaning, spraying, rust removal, and strengthening at home and abroad.

This product uses carefully selected scrap steel raw materials, added rare metals and proportioned alloys, melted in an electric furnace, and produced into steel particles through modern equipment. After repeated electric heating treatment and automatic screening, its chemical composition and particle size are strictly controlled during the process of forming steel particles from liquid metal to ensure that its mechanical properties meet various applications. Each production process has strict quality control, and the alloy steel balls produced have a tight internal structure, are not easily broken, have uniform particle size distribution, moderate hardness, strong impact resistance, and long service life.
The alloy steel shot blasting equipment produced needs to be maintained strictly according to the necessary maintenance procedures after installation and commissioning. All oil injection points of the equipment should be regularly filled with engine oil, lubricating oil, or grease according to the requirements of their parts. It needs to be checked every day. If damaged, it should be replaced immediately. Operators should always pay attention to checking the cleanliness effect. If there is any abnormality, the machine should be stopped immediately and the equipment should be inspected.
The steel and iron shot used in shot peening are not actually balls. More precisely, it was a small steel wire or bar that took some time to look like a ball. To put it simply, the so-called sandblasting sand is just river sand, which is not much different from that used in construction. It is just screened sandblasting with less mud and particle size specifications. Of course, some industries are also different. For example, in the shipbuilding industry, alloy steel shot is used for shot blasting, and metal ore is used for sandblasting.

As stated in the above article, each process in the manufacturing of alloy steel shot has certain principles and significance. If there are no necessary processes, they can be omitted, which not only does not help the product, but may even affect the quality of the product itself, greatly increasing costs.
