Late stage of steel ball production

The subsequent processes of steel ball production, including automatic cleaning of steel balls, automatic appearance inspection (automatic removal of non-conforming products), automatic rust prevention, and counting packaging, are all key factors that affect the quality of steel balls. Appearance inspection of steel balls is an indispensable process in the processing of steel balls. The appearance inspection of steel balls mainly includes surface scratches, rust, surface spots, and other aspects. Steel ball production process: stamping - polishing - quenching - hard grinding - appearance - precision grinding - cleaning - rust prevention - finished product packaging.

The purpose of steel balls

Steel balls are widely used in fields such as electricity, building materials, mining, and metallurgy.

Factors affecting the quality of steel balls

① Material influence: Steel balls, cast iron balls, alloy steel balls, etc. The density of different materials varies. The density of steel is higher than that of cast iron, while alloy steel varies depending on the density and content of the main alloying elements.

② The influence of steel ball manufacturing methods: The microstructure of rolled and forged steel balls is dense, resulting in high density. The microstructure of cast steel balls, cast iron balls, or cast alloy balls is not very dense, and even has pores, resulting in lower density.

③ The influence of metallographic structure of steel balls: The density varies under different crystal structures such as martensite, austenite, bainite, and ferrite, which also affects the crystallinity.
