The production process of forged steel balls: a meticulous and complex Technique 

The production process of forged steel balls is a meticulous and complex technique, involving multiple stages and steps, 

each of which is crucial and directly affects the quality and performance of the final product. Below, we will provide a detailed 

analysis of the production process of forged steel balls to better understand and master this technology.

1. Selection and Preparation of Raw Materials ( China Steel#） 

The raw materials for forging steel balls are mainly high-quality steel, which must have good plasticity and toughness to 

ensure that the required shape and size can be formed during the forging process. In the raw material preparation stage, 

strict screening and testing of the steel are required to ensure that it meets the production requirements. At the same time,

 the steel also needs to be cut and pre-treated for subsequent processing and forging.

2. Heating Treatment and Preheating

Before forging, steel needs to be heated to a certain temperature to enhance its plasticity and reduce deformation resistance. 

Heating is usually carried out by flame heating or electric heating. By controlling the heating speed and temperature, 

it is ensured that the steel is heated evenly during the process to avoid overheating or overburning. Preheating is to reduce 

the temperature gradient of the steel during the forging process and minimize the occurrence of deformation and cracks.

3.  Forging Process

Forging is the core process in the production of forged steel balls. It involves shaping heated steel through plastic deformation 

to achieve the desired shape and size. The forging process consists of multiple steps, such as blanking, pre-forging, and final forging. 

During forging, parameters such as forging temperature, forging speed, and forging pressure need to be strictly controlled to 

ensure uniform deformation of the steel without cracks or defects. Additionally, regular maintenance and replacement of forging 

dies are necessary to maintain their accuracy and lifespan.

4. Heating Treatment and Cooling Method 

After forging, the steel balls need to undergo heat treatment to eliminate internal stress and improve the microstructure and 

performance. Heat treatment usually includes normalizing, quenching and tempering, etc. By controlling the heating and cooling rates, 

the steel balls can achieve the required hardness and toughness. After heat treatment, the steel balls need to be cooled and cleaned to 

remove oil and oxide on the surface, preparing for subsequent processing and inspection.

5. Quality Inspection and Evaluation System 

Quality inspection of forged steel balls is a crucial step in the production process, as it directly affects the quality and performance of

 the products. Quality inspection encompasses multiple aspects such as visual inspection, dimensional measurement, hardness testing, 

and impact toughness testing. Through comprehensive inspection and evaluation of the steel balls, defects and substandard products 

can be detected and eliminated in a timely manner, ensuring that the quality and performance of the products meet the standard 

requirements.
