The quenched cast steel shot achieves the best service hardness

  Cast steel shot is also widely used in the casting industry. When the workpiece is removed from the mold, the sand on the workpiece surface is removed with cast steel shot. When used with suitable equipment, cast steel shot is definitely the best abrasive for surface cleaning because of its durability. 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. Because the surface color of tempered iron 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 into the ball mill and match the ball reasonably according to the diameter and proportion, but it is not necessary to install separately when the ball mill is installed. Since the mill cylinder is integrated and installed separately, it is useless, and it will be mixed even when running With the progress of production, the medium will wear less, and the ball needs to be added regularly This troublesome and useless separate ball loading affects production When adding the ball, just install it according to the size and proportion The ball shape and small hardness make the cast steel shot not cause great wear to the equipment. The quenched 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.

  Workpiece coating, workpiece bonding pretreatment and sand blasting can remove all dirt such as rust on the workpiece surface, and establish a very important basic schema on the workpiece surface. Moreover, it can achieve different degrees of roughness by exchanging abrasives with different particle sizes, and greatly improve the binding force between workpiece and coating and plating materials. Cast steel shot is used for pretreatment of steel plate and is generally used for rust removal before coating. There are many kinds of cast steel shot. Different steel shot requires different raw materials and equipment.
