Steel ball production
The post-process of steel ball production, namely automatic cleaning of steel balls, automatic appearance inspection (automatic rejection of non-conforming products), automatic rust prevention, counting and packaging, are the key factors affecting the quality of steel balls. The appearance inspection of steel balls is an indispensable process in the processing of steel balls. The appearance inspection of steel balls mainly includes the detection of surface scratches, rust, surface spots and the like. Steel ball making process: stamping - light grinding - quenching - hard grinding - appearance - lapping - cleaning - anti-rust - finished packaging.
Use of steel balls
Steel balls are widely used in electric power, building materials, mining, metallurgy and other fields.
Factors affecting the quality of steel balls
1 Material influence: steel ball, cast iron ball, alloy steel ball, etc. The density of different materials is different, the density of steel is larger than that of cast iron, and the alloy steel is different depending on the density and content of the main alloying elements.
2 Influence of steel ball manufacturing method: The rolled and forged steel balls are dense in structure, so the density is large, and the microstructure of cast cast steel balls, cast iron balls or cast alloy balls is not dense, and even there are pores, so the density Smaller.
3 The influence of the metallographic structure of the steel ball: the density of different crystal structures such as martensite, austenite, bainite and ferrite is also different, which also affects the crystal fineness.
