Bar medium frequency induction heating furnace

1 , bar material medium frequency induction heating furnace use:

This set of bar medium frequency induction heating furnace is mainly used for the overall heating of bars with a diameter of 75 mm and a length of 100-150 mm . The final heating temperature is 1100 °C. Bar material medium frequency induction heating furnace to ensure heating workpiece processing tempo reaches 10 seconds / piece . Core surface temperature difference : less than 50 °C

2 , bar material intermediate frequency induction heating furnace selection method

3 , the main technical indicators and characteristics of bar medium frequency induction heating furnace :

1. Thyristor intermediate frequency power supply :

1.1 power is 800KW , The frequency is 1000Hz .

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 The temperature switch is installed on the sensor coil, and it will stop automatically when the water temperature exceeds 65 °C. When not working, the condensate in the inductor coil can be discharged through compressed air.

2. The connection of the 7 waterway is a quick connector. For the reliable connection and quick change of the connection, several large stainless steel bolts are used.

3 , the console

The display panel is equipped with a display of intermediate frequency voltage, power, DC current, and an intermediate frequency power control switch, manual automatic knob, power adjustment knob and emergency stop button, and other related operation controls and push button switches.

4 , the description of the work process :

The operator manually discharges the unheated workpiece on the storage platform. Under the action of the cylinder, the pushing mechanism pushes the workpiece rolled into the furnace pushing groove into the induction furnace for heating according to the set tempo. The mechanical structure part design requires firmness, flexibility, reasonableness, and convenient operation and maintenance.
