Application Of Steel Balls

1. Machinery manufacturing: Steel balls are widely used to make mechanical components such as bearings, transmission chains, and couplings, as well as transmission media and spare parts for machines, such as rolling bearings, welding coils, clamping tools, etc.

2. Metallurgical field: Steel balls are widely used to make steel processing equipment, such as media, mixers, and filters in high-temperature smelting processes.

3. Aerospace: Steel balls have important application value in the aerospace field, such as manufacturing rocket thruster nozzle materials, bearings, shock absorbers, and other key parts to improve the overall performance of the aircraft.

4. Construction industry: Steel balls can be used in building decoration and guardrail railing structures in the construction industry.

5. Crushing industry and bearing industry: Steel balls are the most important components of these industries, such as those used to manufacture high-speed, low-noise special bearings, high-precision, low-noise motor bearings, household appliance bearings, etc.

It is widely used in grinding industries such as iron ore and non-ferrous metal mine dressing plants, cement plants, thermal power plants, refractory materials plants, steel plants, and phosphate fertilizer plants.
