Steel ball

Steel ball is the most important component of bearing and the most used rolling body in bearing industry. The quality of steel ball directly affects the quality of bearing steel ball is an important basic component, especially the precision industry steel ball plays a great role in the development of national economy. The special materials of steel balls are often required under certain special conditions

The development of steel ball

Steel ball is an important basic component; especially precision industry steel ball plays an important role in the development of national economy. In some special conditions, special materials of steel balls are often needed to achieve the required functions in different environments. In fact, some special steel balls have been widely used in various fields of the national economy, including 9Cr18, 3Cr13 stainless steel, copper, aluminum, titanium alloy steel and agate, glass, ceramic ball, etc. Their popularization and application not only promoted the development of steel ball production industry, but also promoted the technological development and technological progress of related industries.

Production of steel ball in the later period

The post-process of steel ball production, namely, automatic cleaning of steel ball, automatic appearance inspection (automatic elimination of unqualified products), and automatic rust prevention, counting and packaging, are the key factors affecting the quality of steel ball. The appearance inspection of steel ball is an indispensable process in the processing of steel ball. The appearance inspection of steel ball mainly includes the inspection of surface scratches, rusts, surface spots and so on. Steel ball production process: stamping –rough grinding -- quenching -- hard grinding – appearance dressing -- fine grinding (polishing) -- cleaning -- rust-proof -- finished product packaging.

Use of steel ball

Steel ball is widely used in electric power, building materials, mining, metallurgy and other fields

Factors affecting the quality of steel ball

(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, alloy steel is different according to the density and content of the main alloy elements.

(2) The influence of steel ball manufacturing method: rolled and forged steel ball of the dense structure, so the density is large, casting cast steel ball, cast iron ball or cast alloy ball, such as the structure is not very dense, and even there are pores, so the density is lower.

(3) Influence on microstructure of steel ball: the density of marten site, austenite, bainite, ferrite and other different crystal structures are also different, which also affects the fineness of the crystal.
