The steel shot after burning reaches the best service hardness

  The manufacturing process of cast steel shot is as follows: first melt the high-quality steel block, then spray the molten steel with high-pressure water to form particles, reheat the formed shot to purify it evenly, and then quench it. Since the surface color of cast steel shot is uniform and blue after annealing, tempered iron shot is often used as cast steel shot, and the service life of iron shot is only 50-400 times. The rust removal effect of iron shot is seriously reduced and the interests of users are seriously damaged.

  It is right to install steel forging for cast steel shot mill and reasonably match the ball according to the diameter and proportion, but it is not necessary to install it separately when it is installed. Since the mill cylinder is integrated, it is useless to install it separately, and it will be mixed even when it runs. With the progress of production, the medium will also wear less, and the cast steel shot needs to be added regularly. Such troublesome and useless separate ball loading affects production. When adding the cast steel shot, just install it according to the size and proportion.

  The cast steel shot shape and small hardness make the cast steel shot not cause great wear to the equipment. The cast steel shot is dried and reheated and tempered in the furnace to achieve applicable hardness. The tempered cast steel shot is divided into different grades through mechanical screen. Products with different particle sizes and hardness are used in different processes, such as surface strengthening.
