Analysis of Three Major Causes Affecting the Quality of Steel Balls
2022-11-17
Steel ball is an important basic component, especially precision industrial steel ball plays an important role in the development of national economy. Under many special conditions, steel balls with special materials are usually required to achieve the capabilities required in different environments. The quality of steel ball directly affects the production efficiency of bearing machinery. What are the key factors affecting steel ball?
The first factor affecting the quality of steel ball: the metallographic structure of steel ball
The density of martensite, austenite, bainite, ferrite and other different crystal structures is also different, and the steel analyzer also affects the crystal fineness;
The second factor affecting the quality of steel ball: material
Steel ball, cast iron ball, alloy steel ball, etc. The density of different materials is different. The density of steel is greater than that of cast iron. Alloy steel depends on the density and content of key alloy elements;
The third factor affecting the quality of steel balls: the production method of steel balls
The rolled and forged steel balls are dense in structure, so the density is high. Forged cast steel ball, cast iron ball or forged alloy ball are not very dense in structure, even with air holes, so the density is much smaller.
