They are respectively applicable to the industrial range of cast steel sand, which is made of high-quality steel scraps. Firstly, they are melted, and then the molten steel is sprayed with high-pressure water to form small balls. The formed pellets are reheated to purify homogeneity, and then subjected to quenching treatment. The quenched shot is dried in the furnace and reheated for tempering to achieve appropriate hardness. The tempered alloy steel shot is sorted into 11 grades that meet SAE standards through a mechanical sieve for use in shot blasting equipment. Products with different particle sizes and hardness are used in different processes, such as surface strengthening.
