Automatic Hot Rolled Steel Ball Production Line

Against the backdrop of rising quality requirements for grinding steel balls from global mining, cement and metallurgical sectors, fully‑automatic hot‑rolled steel ball hot rolling heating production line have become the preferred solution for steel ball plant renovation, thanks to low‑labor input, high throughput and stable product performance. With decades‑long experience in induction heating and complete‑set steel‑ball equipment, Forever Electromechanical breaks down core units of a standard automatic hot‑rolled steel ball production line. This overview delivers clear reference for new‑plant planning, equipment selection and legacy‑line retrofitting for global manufacturers.

1. Automatic Loading & Feeding System
2. Equipped with material rack, servo conveyor and positioning unit, this module sorts, arranges and feeds round bars continuously. It replaces manual feeding and stabilizes material supply for heating and rolling, compatible with bar sizes from 20 mm to 150 mm.
3. IGBT Induction Heating System
4. It acts as the thermal heart of the whole line. Composed of medium‑frequency induction furnace plus closed‑loop infrared temperature measurement device, it heats steel bars rapidly to rolling temperature. Thermal efficiency reaches over 90 % with minimal oxidation loss. Temperature fluctuation is controlled within ±10 ℃, laying reliable metallurgical foundation for rolling and cutting down overall energy consumption.

6. Skew‑rolling Main Mill
7. The forming core of the production line. Fitted with customized spiral roller sets, it realizes plastic deformation via skew‑rolling pass to produce high‑roundness steel ball blanks. Featuring rigid frame and easy roller replacement, the mill determines ball roundness, dimensional tolerance and hourly output capacity.
8. Steel Ball Conveying & Separating Mechanism
9. Rolled ball strings are transported and separated automatically. Connecting ribs and waste scraps are removed to prevent material jamming and guarantee non‑stop continuous running of the whole plant.
10. In‑line Quenching Unit
11. Hot steel balls coming out from rolling mill go straight into quenching station. Cooling medium flow rate and holding time are precisely regulated for surface hardening. Waste heat from rolling process is fully reused to avoid extra reheating and cut energy cost.
12. Tempering Furnace
13. Tempering process eliminates internal stress after quenching, balancing hardness and impact toughness of finished balls. This unit is critical to lower fragmentation rate for grinding balls under heavy‑load working conditions.
14. PLC Central Intelligent Control System
15. Serving as the brain of the line, it integrates linkage control over temperature, rolling speed and material transfer. Operators can adjust parameters for heating, rolling and heat‑treatment on one panel. Only four workers are needed for one complete line. Functions including data logging and fault alarm support convenient on‑site and remote operation & maintenance.

Forever Electromechanical supports modular customization according to client‑specific capacity and ball‑size requirements. We deliver full turn‑key solutions as well as partial upgrading service for existing workshops, helping worldwide wear‑material manufacturers achieve automated and eco‑friendly production.
