Description
Primary Applications
Designed for quench-and-temper processing of steel bars, low-carbon alloy bars, wind-power bolts, anchor/foundation bolts, lead/ball screws, and hydraulic cylinder rods. The line delivers controlled quenching and tempering with high productivity and precise process control.
Specifications & Working Range
Power System
- Quenching: 160–3,000 kW @ 0.5–4 kHz
- Tempering: 100–2,000 kW @ 0.5–2.5 kHz
Throughput
0.5–7 t/h (depending on size, grade, and process route)
Size Envelope
- Diameter: Ø20–Ø200 mm
Conveyor & Mechanical Design
Helical Roller Geometry
Roller axes are set at a defined angle to the workpiece axis so each bar rotates while advancing at constant speed, improving circumferential and through-section heating uniformity.
Roller Materials
- Between inductors: non-magnetic 304 stainless-steel rollers with water cooling for thermal stability and long service life.
- Other sections: 45# (C45) steel with surface hardening for wear resistance.
Grouped Roller Control
Infeed, heating (inductor), and outfeed roller groups are independently controlled. This stabilizes continuous heating, reduces inter-part gaps, and supports consistent residence time.
Control & Automation
Closed-Loop Temperature Control
Infrared pyrometers integrated with a PLC form a closed loop for both quench and temper sections, maintaining setpoints and minimizing temperature deviation.
Industrial PC (IPC) HMI
Real-time display of operating parameters with data logging, recipe storage, print/export, fault indication, and alarms, supporting safe operation and traceable quality.
System Advantages
- High Productivity: Processes 0.5–7 t/h to meet mid- to large-scale production requirements.
- Efficient Heating: Uniform, precisely controlled induction heating improves metallurgical consistency and reduces rework.
- Energy-Conscious Operation: Modern induction power supplies with high power factor help lower specific energy consumption.
- Operator-Friendly: Advanced temperature control and equipment management simplify operation, changeover, and maintenance.
