Hardness of quenched cast steel grits for optimum use

  Cast steel grits is also widely used in foundry industry. When the workpiece is removed from the mould, the cast steel grits on the workpiece surface is removed by cast steel grits. When cast steel grits is used with suitable equipment, because it is durable, it must be the best abrasive for surface cleaning. The manufacturing process of G40 Cast Steel Grits With ISO 9001 is to melt high quality steel blocks first, then use high-pressure water jet to make molten steel particles, the formed pellets are re-heated to purify uniformly, and then quenched. Because the surface color of tempered cast steel grits is uniform blue after annealing, tempered cast steel grits is often used as cast steel grits.

  The service life of cast steel grits is only 50-400 times. The effect of rust removal of cast steel grits is seriously reduced and the interests of users are seriously damaged. It is right to fit steel forging cast steel grits reasonably according to the diameter and proportion of cast steel grits mill, but it is not necessary to install separately at large.The spherical shape and smaller hardness will not cause greater wear and tear to the equipment. Quenched pellets are dried and reheated in the furnace to achieve suitable hardness. The cast steel grits after tempering are divided into different grades through mechanical screen. Products with different particle size and hardness are used in different processes, such as surface strengthening.

  Workpiece coating and sand blasting before bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece. Moreover, by changing abrasives of different sizes, different degrees of roughness can be achieved, and the bonding force between the workpiece and coatings and plating materials can be greatly improved. Cast steel grits is used for steel plate pretreatment, usually used for rust removal before painting. There are many kinds of cast steel grits. Different kinds of cast steel grits require different raw materials and equipment. The production of cast steel grits, as well as related production lines and equipment, can be purchased directly. There are many places where cast steel grits are needed, such as castings, forgings, parts surface after machining, parts surface after heat treatment, etc.

  They can be sold to these related places, such as general manufacturing, shipbuilding and so on. Generally heavy industry will have some demand. Advanced foundry technology and equipment: Adopting international advanced anhydrous production technology, even applying completely dry resin sand on metal film, completely eliminating casting defects such as pore and slag inclusion caused by water content in sodium silicate, making a qualitative leap in product quality, and improving iron-carbon ratio, fully adapting to quenching requirements.
