Actually in daily life, we often use to different types of castings, and in the actual use, there are a lot of advantages, also find casting like alloy steel castings, high hardness, then we should how to chemical treatment:

1, polishing method: is the brush roll under the drive of the motor, brush roller and the rolled piece movement in the opposite direction in the plate with the top and bottom surface of high speed rotating brush to tin oxide. Brush away the iron oxide using washing system of closed cycle cooling water bath. Will the projectile blasting method of cleaning is the use of centrifugal force to accelerate, projectile to the alloy steel castings for descaling cleaning method.

2, shot peening method: divided into shot peening and sand blasting, surface treatment by shot peening, force is big, clean effect is obvious. But the processing of shot peening on sheet workpiece, easy to deformation, alloy steel castings and steel shot hit the surface metal base material deformation, with oil so artifacts, shot blasting, shot peening cannot remove grease. On the surface of the workpiece that existing processing method, the cleaning effect is good also for sand blasting. Sandblasting applicable for higher requirements for surface cleaning.

In the process of the production of alloy steel castings, through some chemical processing, after the chemical treatment, in the process of using the casting, has the quite obvious effect. And changes in plants could also improve their quality.
