After quenching, the cast steel shots reaches the best hardness

  Cast steel shot is also widely used in the casting industry. When the workpiece is taken out of the mold, the sand on the surface of the workpiece is removed with cast steel shots. When the cast steel shots is used with suitable equipment, because it is durable, it must be the best abrasive for your surface cleaning. The manufacturing process of cast steel shot is to melt the high-quality steel block first, then spray the molten steel with high-pressure water to form particles, reheat the formed shot body to purify evenly, and then quench.

  After annealed, the surface color of tempered cast steel shots is uniform blue. Tempered cast steel shot is often used as cast steel shot. The service life of cast steel shots is only 50-400 times. The rust removal effect of cast steel shots is seriously reduced and the interests of users are seriously damaged. It is right to install steel forging for ball mill to match ball reasonably according to diameter and proportion, but it is unnecessary to install separately when the ball mill is installed. Since the mill barrel is integrated and installed separately, it is useless, and it will be evenly mixed when it is running. As the production goes on, the medium will also wear less, It is necessary to add cast steel shots regularly.

  This troublesome and useless separate ball loading affects the production. When adding the ball, it should be installed according to the size and proportion. The shape of the cast steel shots and the smaller hardness make the cast steel shots not produce greater wear on the equipment.  After quenching, the cast steel shot is dried and reheated in the furnace for tempering to achieve the applicable hardness. The tempered cast steel shots is divided into different grades and other products through the mechanical screen.

  The products with different particle size and hardness are used in different processes. The abrasive with different particle size can be exchanged to achieve different degree of roughness and greatly improve the binding force of workpiece, coating and plating material. Cast steel shots is used for steel plate pretreatment, generally used for rust removal before coating. There are many kinds of cast steel shots. Different steel balls need different materials and equipment.
