Character of GCr15
Good overall performance, good cutting performance after spheroidizing annealing, high and uniform hardness after quenching and tempering, high wear resistance and contact fatigue strength and good thermal processing performance. Contains more alloying elements and is cheaper. GCr15 steel is the most used and produced high carbon chromium bearing steel, and is widely used in the world. However, it has strong white spot sensitivity, poor welding performance, high and uniform hardness, and good wear resistance. Used to make small cross-section quenched and tempered parts with larger load and large normalized parts with less stress.
Steel balls are important basic parts, especially precision industrial steel balls play a huge role in the development of the national economy. Under some special conditions, steel balls of special materials are often needed to fulfill the functions required under different environments.
Category
1. From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls in the crushing industry and bearing steel balls in the precision bearing industry.
2. Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process.
3. According to the processing material, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls and alloy balls.
4.According to the appearance, it can be divided into a round ball (general narrowly defined name), capsule ball, elliptical ball, yin and yang ball, hollow ball, multi-faceted ball, multiple missing ball (with dimples on the surface), etc.
Note of GCr15:
1. The residual copper content (melting analysis) of the steel for bearing steel pipes should not exceed 0.2%.
2. The oxygen content is measured on the billet or steel.
3. The sulfur content (melting analysis) of wire rod steel should not exceed 0.02%.
Application
Steel balls are widely used in bearings, the manufacture of steel balls, rollers and bushings on drive shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles and mining machinery.
Production
The post-processes of steel ball production, such as automatic steel ball cleaning, automatic appearance inspection (automatically reject unqualified products), automatic rust prevention, counting and packaging are all key to the quality of steel balls. Steel ball appearance inspection is an indispensable process in the process of steel ball processing.
The appearance inspection of steel balls mainly includes the inspection of surface scratches, rust, and surface spots.
Steel ball production process: stamping-smooth grinding-quenching-hard grinding-appearance inspect -fine grinding-cleaning-rust prevention-finished product packaging.
