C, the main technical indicators and characteristics of bar medium frequency induction heating furnace :
1. Thyristor intermediate frequency power supply :
1.1 power is 100KW , The frequency is 6 000 Hz .
1.2 startup success rate can reach 100%
1.3 rectification power factor is greater than or equal to 0.92
1.4 with temperature interface for temperature closed loop control
1.5 with internal and external conversion and automatic manual conversion
1.6 multi-station structure can easily and quickly replace the furnace body according to different heated workpieces
1.7 IF voltage 750V
1.8 DC voltage 500V
1.9 all-digital, no relay control loop, making the system stable and reliable
1.10 with over-current, over-voltage, under-pressure, phase loss, water pressure, water temperature and other complete protection, to ensure that any failure does not damage the bar medium frequency induction furnace components
1.11 three-phase incoming line does not divide the phase sequence, can be connected arbitrarily
1.12 Easy-to-use "fool" type bar material medium frequency induction heating furnace , never misunderstanding
2. Induction heater :
2.1 Induction heater is a quick change joint structure.
2.2 The sensor is made of high quality knotted knots.
2.3 The inner guide rail of the sensor is specially treated and polished.
2.4 The inductor coil, bus bar and connecting wires have a large cross-sectional area to reduce heat generation.
2.5 The internal connection of the inductor coil is reliable, the inductor is manufactured strictly according to the process requirements , and the high pressure leak test before assembly.
2.6 When not working, the condensate in the inductor coil can be discharged through compressed air.
3 , the description of the work process :
The operator manually discharges the unheated workpiece on the feeding trough, and the pushing mechanism pushes the workpiece rolled into the furnace pushing trough into the induction furnace under the action of the cylinder. The mechanical structure part design requires firmness, flexibility, reasonableness, and convenient operation and maintenance.
