Role of cast steel shot in rust removal treatment

　As a common material for metal surface treatment, cast steel shot is also in great demand in industry. Especially in the process of deoxidization and rust removal before coating, centrifugal shot blasting equipment is often used in this situation. The spherical shape and smaller hardness make the cast steel shot not cause greater wear and tear to the equipment. Cast Steel Shot S390 is also widely used in foundry industry. When the workpiece is removed from the mould, the sand on the workpiece surface is removed by cast steel shot.

　　Melt the high quality molten steel, then spray the molten steel with high pressure water spray gun to form cast steel shot.

　　The formed cast steel shot are reheated to homogenize, and then quenched. Quenched cast steel shot are dried and reheated in the furnace to achieve proper hardness. Products with different particle size and hardness are used in different processes, such as rust removal of steel, surface strengthening, etc. When adding new cast steel shot, please observe the principle of small amount of diligence.

　　The cast steel shot is made of scrap steel with selected raw materials, rare metals and optimum proportion alloys, melted in electric furnace, converted into cast steel shot by modern equipment, and after many times of electric heat treatment and automatic screening, its chemical composition and particle size are strictly controlled in the process of forming cast steel shot by liquid metals, so as to ensure its mechanical properties are in conformity with each other. For various purposes.

　　Each production link has the most rigorous quality management. The cast steel shot produced are tightly organized, not easy to break, uniform particle size distribution, with appropriate hardness, strong impact resistance and long service life.

　　The role of steel balls in deoxidizing scale and rust removal is very huge. Although it can be reused, its market is still very broad.
