Equipment introduction

Intelligent series induction heating power

Application: diathermic forging, melting, quenching, tempering, annealing, and tempering.

Function Features

①Frequency adaptive: After process is adjusted and load changes, the power frequency automatically tracking, automatically hopping to the load of the best resonant frequency. Frequency adaptive range 40KHz.

②Load adaptive: After the process is adjusted and the load changes, the power supply and load are automatically matched to the best working state to achieve high production efficiency, quality consistency and equipment reliability

③Automatic power adjustment: stepless adjustment range 10% -100%.Royce  digital IGBT inverter induction power has strong linkage with temperature, to control the heating temperature precisely and stably through the power and temperature automatic adjustment system .

④High power factor: Adopt the parallel chopper technology, any load matching, in case 10% -100% power output, the power factor greater than 0.93, do not need a separate power compensation device, both to reduce equipment investment and enable users to reduce electricity costs and increase Power supply, decrease high harmonics, and improve power quality.

⑤0.2 seconds fast start at any load and any temperature, 100% start-up success rate, 0.1% repeat accuracy.

High reliability

①Intelligent protection system: adopt special diode protection technology, never burning diode; using IGBT speed protection technology, so that IGBT longer life; transformer primary, capacitor, output bus ignition protection; workpiece or billet and sensor contact spark protection . Users can also choose customized power protection program according variety of conditions.

②DSP digital control device, the parameters are cured in the process, the environment changes will not have an impact on the internal parameters. Digital power with high stability / high transmission speed/ high precision / easy to adjust the process, a single control board, a high degree of integration, fewer points of failure.

③Choose international renowned brand components, all light transmission signal to avoid interference, let the power supply run more stably.

④Good anti-voltage fluctuation performance: Voltage fluctuation range between 350V-440V, the output power fluctuations ± 1 ‰, does not affect product quality.

Intelligent control system

①Industrial touch screen display

②Quality Monitoring system and quality traceability: Effectively documenting events occurring during operation, including operations, data parameters, faults, alarms, product batches, operator numbers, etc., as a database. And quickly find historical data and curves based on the previous daily work records, analyze the reasons for quality problems and ways of improvement.

③Operating status Real-time monitoring / remote control: DSP processor real-time monitoring of the operating status and parameters of the power supply (such as voltage, current, power, frequency, temperature, etc.) These states can be directly connected to the control network through the RS485 interface within the power, transmit the required parameters to other controllers.

④Fault self-diagnosis function / online display and processing: When there is  misoperation by operator or special conditions causing alarm, the touch screen will display the fault content, click the corresponding fault help you can query the corresponding fault solution. Make more than 90% of the common faults quickly processed by the operator, greatly improving production efficiency and reducing the dependence on manufacturer.

⑤Process customization and process parameter control: The Variable frequency power parameters are integrated into the user's manufacturing system and quality control system. The user or the host manufacturer can modify the programming or process according to the technical requirements of the process. Power reserve RS485 interface on the motherboard. You can print or download the process modification and comparison at any time which is recorded in the system .

⑥Power monitoring: the monitoring records of inlet voltage, power factor, single piece of energy consumption and batch total energy consumption , can effectively calculate and control the cost of production.

Production features

1.Using Siemens Infineon IGBT inverter, series / parallel resonant circuit, the conversion efficiency more than 90%.

2.Can adjust the heat insulation process power, time, help to improve the quality of heating and heating repeatability, simplifying the operation of workers.

3.Installation is simple, connect with three-phase 380V power supply, inlet water, outlet water can work.

4.Comparing with the same power level SCR induction heating equipment, IGBT induction heating equipment reduced size by 1/2 and weight by 2/3. Theoretically save more than 15% electric energy. Small footprint, easy to operate.

5.Regardless of the output power, the power factor is always not less than 0.95. 100% startup under any load. With automatic frequency tracking function, the entire process can always ensure high power factor.

6.Replacing the reverberatory furnace, gas furnace, heating without fire, in line with national fire safety regulations.

7. With double closed-loop control function, can speed up the heating at maximum level,and optimize the heating process of metal parts.

8.The entire control system are digital integration, fast action of  variety protection , low failure rate of the whole machine, long life.

9.Start fast, can be fully activated in 0.2 seconds , 100% started successfully.

10. Quenching process, the power and CNC machine tools can detect each other start signal, form closed-loop control to prevent inconsistencies start when quenching and affect the consistency of product quality.

These successful cases are the practical application of our equipment for different products and different technology, if you want to know what process your product needs to meet the technical requirements, please contact us according the information in website, we will provide you with a complete solution.
