Shunt capacitor: one set (under the furnace)

Power factor: Full power state arrive more than 96%.

A. Advanced control system:

The frequency power uses intelligent control system, it is a new SCR generation control system designed by absorbing the advance frequency heating technology both Chinese and foreign and special requirement for cylinder. The intelligent control system uses line unit design, all working units have luminotrons to display working state, the calculation of control system is processing in the special CPU module. It is reliable, steady and easy to maintain.

B. Adjustable power output:

During the power of equipment is 0 - rated power can be adjusted continuously, increasing the power adjustment output function, the low power of 9KG cylinder operation can guarantee the best working state, to ensure the commutating voltage reach 500V, improve the heating efficiency and save the energy consumption.

C. Complete protection function:

Not only equip with over-voltage protection, over-current protection, voltage restriction, current restriction functions, but also the intelligent protection system has the reliable release circuit while using the over-voltage high voltage, improve the frequency power running steady greatly, and has the over-temperature alarm function of cooling water temperature.

D. Obviously energy saving:

Retain all original functions in the intelligent control system, The unique design of the regulating function of impedance in the working process of the equipment according to the furnace workpiece (charge) impedance changes during heating (the inherent characteristics of the workpiece, the burden is in the process of heating) the working parameter adjustment of inverter power supply, the working efficiency is the highest in the state, so the high efficiency, energy saving, time saving. Frequency power intelligent impedance adjustment function, intelligent protection function is the domestic unique technology

E. Reliable starting system:

Zero voltage sweep frequency starting mode without impact, and the impedance adjustment function in the intelligent control system, making the essence of starting ability of frequency power has been greatly improved.

F: Automatic testing frequency output:

Intelligent control system, testing the change of system inductance caused by the cylinder temperature changing during the heating process automatically, adjust the output parameter in real time, making the whole heating process stay in high efficiency state and saving energy.

G: Simple troubleshooting:

Digital intelligent control system has fault display function, easy to find the fault, you can find the fault of the intelligent system without inspecting the equipment. Easy to maintain.

2. Heating normalizing furnace

Setting heating process (set heating time and heating temperature), automatically control heating temperature and propulsion system. The electric control system sends out the instruction to complete a series of actions, such as pushing the cylinder into the furnace, heating, measuring temperature, and unloading cylinder, to ensure the whole process working as the setting parameter. Process requirements set on the touch screen, pushing the cylinder into the furnace, heating, temperature, unloading cylinder of a series of actions by the PLC control. The heating process parameters of each cylinder are recorded in the touch screen, and the temperature recording data can be extracted through the U disk. It can print the heating process parameter of all cylinders or check some printed cylinders. It can be operated by the operation table printer or print by U disk. During working touch screen display setting heating temperature, cylinder temperature, display and record the maximum cylinder temperature. Display and record the number of heating cylinders. For the occasional unreasonable data can be modified later.

It can also be provided with a heating speed, so that the pushing mechanism can push out the cylinder according to the set speed.
