Is there no difference between high chromium balls and medium chromium balls, low chromium balls, and forged steel balls?
2015-09-26
Different quality indicators for high chromium balls: Chromium content ≥ 10.0% and carbon content between 1.80% and 3.20% are called high chromium balls. According to national standards, high chromium balls must have a hardness (HRC) of 58 or above and an impact value of ak ≥ 3.0J/cm2. To achieve this hardness, high chromium balls must be subjected to high-temperature quenching and tempering treatment (currently, there are two quenching methods in China: oil quenching and air quenching), If the hardness (HRC) is lower than 54, it indicates that the steel ball has not undergone quenching treatment.
The production process of steel balls
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
Common problems and introduction of steel balls
2023-04-25
The quality of the steel ball determines the efficiency of the work process, and if the purchased steel ball does not meet the quality standards, it will cause the steel ball to be easily damaged during the work process. Crushing: mainly because the composition of the steel ball does not meet the standards, the method is not handled properly, or the use of inferior materials causes the steel ball to contain impurities, which is why it is broken.
The influencing factors in steel ball production
Material density affects: steel balls, cast iron balls, alloy steel balls, etc. The density of different materials varies. Steel has a higher density than cast iron, while alloy steel varies depending on the density and content of the main alloying elements.
