Φ80 round bar forging furnace

A, overview:

It is suitable for induction heating before steel bar forging, round bar forging furnace starting mode is zero pressure sweep frequency, power saving type product. The round bar forging furnace structure selects the split type single-station furnace body form, which has the advantages of reasonable structure, high electric efficiency, convenient installation of water and electricity, quick and labor-saving of replacing the furnace body and the like. The single round bar forging furnace includes a set of KGPS series thyristor intermediate frequency power supply control system, one GTR series induction heating furnace body, one set of reactive compensation capacitor set, one set of pneumatic feeding system, one set of discharging system and all A set of stainless steel closed cooling towers, etc.

The round bar forging furnace has perfect safety protection measures such as water shortage protection, phase loss protection, over current protection, over voltage protection, under voltage protection, and high water temperature protection. The round bar forging furnace is arranged at 300KW, leaving sufficient power margin to ensure continuous and stable production of the round bar forging furnace for 24 hours. All exposed conductors are installed in the locked electric control box and have eye-catching safety warning signs, so there will be no electric shock. Each interlocking device can avoid damage to the round bar forging furnace or the induction coil copper tube due to manual misoperation.

Manually put the workpiece into the guide trough, the feeding cylinder pushes the workpiece into the induction furnace according to the set beat, and the quick discharge mechanism is designed at the discharge port. This mechanism can effectively prevent the workpiece from falling in front of the tap. The upper layer of the furnace body is scratched, and the workpiece can be quickly taken out from the furnace to the forging machine, which greatly reduces the labor intensity of the worker, and also avoids the loss of energy caused by excessive temperature drop of the workpiece.

Power frequency and power

The diameter of the heated workpiece is relatively large. It is especially important to select the appropriate frequency in consideration of the temperature difference of the core. The theoretical calculation combined with the actual experience, heating the workpiece diameter of 80mm, the round bar forging furnace frequency is preferably 1000Hz.

According to the workpiece parameters, frequency and heating tempo given by the user, the required round bar forging furnace power is 286 KW. Considering the working margin of the round bar forging furnace, 300 KW is selected.

C, electrical technical description

    The electrical part of the round bar forging furnace includes an intermediate frequency power supply control system, a reactive compensation capacitor bank, an induction furnace body, a feed control system, and an electric discharge system.

This electric furnace round bar forging furnace uses KGPS series power-saving thyristor intermediate frequency power supply, adopts 6-pulse rectification mode, the model is KGPS300/1.0 set

D, induction furnace body description

The induction furnace body includes a furnace frame, an induction furnace body, a bus bar, an insulated column, and a main circuit copper row. The furnace body is designed and manufactured according to the single station, and the connection of water and electricity is adopted in the form of quick change, and the replacement of the furnace body is more convenient and convenient.

E. The selection of the mechanical transmission part of the round bar forging furnace:

1, the mechanical transmission part includes: pneumatic feeding system, fast discharging device and other components.

2. After manually sending the workpiece to the feeding trough, the workpiece is sent to the induction furnace for heating according to the set beat by the feeding cylinder. The heating beat has digital display time relay control, and the control precision can reach 0.1 second.

3. The quick discharge machine uses a roller discharge mechanism at the mouth of the furnace.

4. The mechanical structure design strength is 3 times higher than the static pressure design strength.

5, all mechanical parts use domestic famous brand pneumatic components.
