Precision steel ball in the development of the national economy has played a very big role,In some special conditions, often need to use special materials to complete the ball in different environments to achieve the required functions,In fact, some special materials of 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 balls.
Precision steel ball production
After the precision ball production process that ball automatic cleaning, automatic appearance inspection (automatically remove substandard products), automatic rust, count packaging, are the key to the quality of the ball.Steel ball appearance inspection is an indispensable process in steel ball processing.Steel ball test mainly include surface scratches, rust, surface spots and other aspects of testing.
The use of precision steel ball
Precision Ball widely used in bearings, hardware, electronics, iron, machinery and equipment, electricity, mining, metallurgy and other fields.
Influencing factors of precision steel ball
1. Material density effects: steel ball, cast iron ball, alloy steel ball, the density of different materials, the density of steel than cast iron,Alloy steel density is due to the main alloy elements of different density and content.
2. Ball manufacturing methods affect: Rolled and forged steel ball of its dense structure, so the density of cast steel ball, cast iron ball or casting alloy ball and other organizations are not dense, and even there are pores, so the density Smaller.
3. Ball microstructure effects: martensite, austenite, bainite, ferrite and other different crystal structures are not the same density, but also affect the fineness of the crystal.
