Grinding Ball Heat Treatment Process

Release time：2025-02-24

Heat treatment is the key to determine the performance of the steel ball, it is like a "sauna" for the steel ball, through heating, insulation, cooling, change the internal structure of the steel ball, improve the hardness, wear resistance and fatigue strength.

1. The first step is heating, heating the ball to a specific temperature to transform the internal organization and prepare it for the subsequent process.

2. The second step is insulation, so that the steel ball can cool down at high temperature to ensure the uniform transformation of the internal organization and improve the performance stability.

3. The third step is quenching, the high-temperature steel ball is quickly put into the cooling medium, just like freezing, so that the surface of the steel ball is hardened instantaneously and high hardness is obtained.

4. The fourth step is tempering, the steel ball after quenching is relatively fragile, and it needs tempering to reduce brittleness, improve toughness, and make the steel ball more durable
