Introduction

GCr15 steel is a representative steel of high-carbon chromium bearing steel with good overall performance. After quenching and tempering, the hardness is high and uniform, and the wear resistance and contact fatigue resistance are high, good thermal workability. After spheroidizing annealing, it has good workability, but it is sensitive to the formation of white spots.

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. There are generally four types of steel ball production methods: forging, rolling, semi-solid forming and casting.

2. 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.

3. Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process.

4. 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.

5. 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.

Application

Steel balls are widely used in bearings, hardware, electronics, iron art, mechanical equipment, electric power, mining, metallurgy and other fields.

Mainly used in 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.
