Enter the pre-calculated kilowatt value of the electrical energy required to melt or heat the charge to a specified temperature; or enter the weight of the charge, the melting temperature, and the specific heat of the furnace charge, and the system calculates the required electrical energy. When the set kWh energy is applied, the control system will automatically reduce the power output value of the variable frequency power supply to the holding power or stop the power supply, and the audible alarm system will alarm. The sintering process of the lining is automatically controlled by the letter provided by the thermocouple. The system includes a thermocouple signal converter and dedicated software.
1, automatic furnace start
A means of preheating a cold lining is provided. Add the required charge to the cold furnace; enter the specified start date' time, power level, and time limit for applying this power. The medium frequency aluminum melting induction furnace melting management system will automatically start the water pump according to the above requirements. The VIP variable frequency power supply, the lining and the charge will be preheated together to prepare for the quick entry into the melting operation. When the preset warm-up time is over, the power supply is automatically cut off.
2, inductance calculation
The average condition of the lining can be displayed based on the change in the inductance of the aluminum melting induction furnace. When the operator needs it, the inductance of the stove can be calculated and stored at the same time.
3. Monitoring of incoming line voltage
The incoming AC voltage is measured to ensure that the incoming voltage is within the correct range. In order to avoid component overload, it can automatically compensate for the fluctuation of the incoming line voltage.
4. Automatic fault diagnosis.
After the power is turned on, automatic fault diagnosis begins. The diagnostic process is divided into two levels of diagnostics to check the operating DC voltage of the electronic circuit. At the same time check the VIP alarm system and system storage RAM tes
