Induction hardening is a process used for the surface hardening of steel and other alloy components. The parts to be heat treated are placed inside a water cooled copper coil and then heated above their transformation temperature by applying an alternating current to the coil. The alternating current in the coil induces an alternating magnetic field within the work piece, which if made from steel, caused the outer surface of the part to heat to a temperature above the transformation range. Parts are held at that temperature until the appropriate depth of hardening has been achieved, and then quenched in oil, or another media, depending upon the steel type and hardness desired.

Main Features of DSP full digital control induction hardening equipment:
1. Leading technology

• Digital intelligent power supply adopts DSP processor control and digital control technology. The control process, data operation and parameter storage of the system are all processed in digital form Environmental changes such as temperature changes do not affect the internal processes and results of the system

2. Touch screen display

• The working state and working parameters of the machine can be displayed directly on the touch screen. The display parameters include: working frequency, oscillating current, dc voltage, dc current, output power and other parameters. Working status includes functions such as load matching instructions

3 Good resistance to voltage fluctuation

• The power grid voltage fluctuates arbitrarily within the range of 350 to 410V, and the power output fluctuates within the range of plus or minus 0.1%, which does not affect the normal production. The high precision of power repeat output makes the product stable and consistent.

4. Powerful communication function

• Interface is reserved to exchange data with external controller (industrial computer, industrial touch screen, laptop, etc.) or central control

5. The signal transmission adopts optical fiber transmission

• The electromagnetic environment inside the power cabinet is complex, and the transmission of weak current signals (such as drive signal, protection signal, feedback signal, etc.) is vulnerable to electromagnetic interference, while the light is not affected by the electromagnetic environment, so these important signals adopt optical fiber transmission to improve the overall stability and reliability of the equipment.

6. Choose intemational famous brand components

• All the key components on the equipment are imported, and the operation of the equipment is more stable. The inverter is IGBT of Germany infineon company. The rectification device is SCR of German semi control, the relay is brand of German weidmuller, and the core control chip is DSP digital processor of American TI.

7 .Intelligent protection function

• Condition of power supply in normal work, if suddenly will automatically latch fault alarm, at this time, all kinds of protection and fault alarm signal, such as: light capacitor, power cabinet to open the door, IGBT power speed protection, diode special protection, over voltage, over current, lack of phase, water flow, water temperature and other protection, to ensure that the equipment is rellable and durable

8. Fault self-diagnosis and online processing

• When the alarm occurs due to wrong operation or special working condition, the touch screen will display the fault content, and the solution to the corresponding fault can be found by clicking the help of corresponding fault. More than 90% of common faults can be quickly handled by operators, which greatly improves production efficiency and reduces the reliance on operators‘ technical level

9. Constant power output mode

• Output power does not change with workplece temperature, high production efficiency and good product quality
