Product Overview
Rod Heat Treatment Production Line is independently developed and manufactured by Hebei Yuantuo Electromechanical. This continuous induction heat treatment production line integrates induction heating, variable-frequency conveying, multi-stage spray cooling and closed-loop temperature control modules for mass quenching of various round rod workpieces.
Application Scope
Applicable workpieces: Heat treatment for drill rods, push rods, torsion bars, stabilizer bars and other rod-shaped parts.
Machining specification: Available for rods with diameter ranging from Ø15 mm to Ø150 mm.
Basic Technical Parameters of Complete Machine
1.Power supply configuration: Rated power 160–1000 KW, operating frequency 0.5–2.5 KHz.
2.Production capacity: The hourly output of Rod Heat Treatment Production Line is 0.5–3 tons.
3.Energy consumption: Adopt quenching processing, power consumption stands at 260~280 kWh per ton of finished workpiece.
Parameter Configuration of Each System
Conveying Roller System
1.Roller layout: The included angle between roller axis and workpiece axis is set at 18°~21°. Oblique V-type roller design drives workpieces to rotate automatically while moving forward for uniform circumferential heating.
2.Roller material: Rollers inside furnace adopt 304 non-magnetic stainless steel with water cooling structure to avoid deformation and magnetization under long-term high-temperature working condition.
3.Grouped control: Rollers are divided into feeding group, inductor group and discharging group with separate electrical control, ensuring gap-free continuous feeding and heating of workpieces.
Spray Cooling System
1.Structural design: Multi-stage annular spray cooling setup; pressure and flow rate of each spray ring can be adjusted independently.
2.Spraying performance: Max quenching water pressure reaches 0.3 MPa. Concentrated cooling water sprays onto workpiece surface with excellent penetration capacity.
3.Flexible adaptation: Cooling parameters can be modified according to different hardenability of raw steel to match diversified heat treatment requirements.
Closed-loop Temperature Control System
1.Hardware composition: Raytek infrared pyrometer is equipped at quenching station and connected with Siemens S7 control system to form full closed-loop temperature control loop.
2.Operating performance: Real-time workpiece temperature collection enables automatic heating power adjustment for high temperature control precision.
Industrial Control System
1.Main control setup: The whole line adopts PLC plus human-machine interaction system; variable-frequency speed regulation is equipped for overall operation speed adjustment.
2.Core functions: Supporting industrial control computer displays real-time operating data; it realizes storage, record and print of workpiece processing parameters as well as automatic fault detection and alarm.
Work process
Core Product Advantages
Superior machining quality
Oblique V-type rollers reduce radial runout of workpieces. Combination of automatic rotation and high-pressure spray ensures uniform quenching layer, improves quenching efficiency and stabilizes tensile strength and toughness after tempering.
Stable equipment operation
PLC + variable frequency control features wide speed regulation range and stable startup, shutdown and speed change.
Controllable production cost
Fixed power consumption per ton facilitates production cost calculation; water-cooled stainless steel rollers have low wear rate to cut later maintenance expense.
Application Fields
Widely used for mass heat treatment of mining drill rods, automotive torsion bars, engineering machinery stabilizer bars and hydraulic push rods.
