Copper tube annealing is often used for heating annealing of copper tubes and round bars to improve metal thermoplasticity. The metal heating workpiece is placed in the induction coil of the alternating magnetic field, and the copper tube heating device has short heating time, convenient temperature control, guaranteed heating quality, improved working condition produce. Therefore, it has more and more applications.

Copper tube annealing PLC intelligent control system :

1, the user needs to provide a touch screen or a remote control console

2 , man-machine interface, easy to operate

3 , real-time adjustment of equipment operating parameters

4 , real-time control of the heating process, and has a recording function

5 , different international language switching

Main features of copper tube annealing :
1. It is used for heating various metal steel tubes such as carbon steel and iron ;
2 , medium frequency and super audio heating copper tube , more heated, more uniform and faster;
3 , copper tube annealing small volume, easy to move, can be used with any forging and rolling equipment;
4 , copper tube annealing allows the copper tube to be heated to the required temperature in a very short time, greatly reducing metal oxidation, saving material and improving the quality of forging;
5 , automatic feeding, automatic feeding, automatic production capacity;
6, brass annealing energy saving, environmental protection, reduce manpower costs and benefits expenses;
7. It is convenient to replace the sensor to meet the different requirements of the overall heating or end heating of the copper tube .

Copper tube annealing uses intelligent induction heating power supply to control its characteristics:
● Parallel resonance design, phase shifting power adjustment, medium frequency annealing furnace mature and stable; more advantages in the high power range above 3000KW .
● DSP control, the speed captures the phase-locked start, meets frequent start and stop, and has a high success rate.
● Variable frequency variable load adaptation, frequency adaptation range 200-10000Hz, induction furnace replacement automatic matching, no manual adjustment is required.
● T2 copper copper row in the cabinet , sandblasted and passivated; low leakage and anti-oxidation, effectively reducing line loss.
● Full touch screen control, pure digital setting, complete process record and strict hierarchical authority. The main parameters can be restored to the factory settings with one key.
● Power single unit power 50-6000KW , frequency 200-10000Hz.
Special advantages of copper tube annealing :
1, a simple brass annealing operation, a feed, unloading flexibility, high degree of automation.
2 , medium frequency induction heating equipment heating speed, less oxide layer, good quality.
3. Precisely control the length, speed and temperature of the workpiece.
4. Uniform heating of the workpiece ; the temperature difference from the surface to the core is small ; the control precision is high.
5. Customize the copper tube annealing sensor according to your specific requirements for design and production.
6. Full range of energy-saving optimization design : low energy consumption and high thermal efficiency.
