Take you to understand the fully automatic temperature closed loop intermediate frequency induction heating furnace

The 750KW/1.0KHZ intermediate frequency induksie verwarming oond adopts three automatic selection mechanisms of feeding, feeding, discharging and temperature. The specially proposed temperature closed-loop control uses two power supplies and three sensors. The thermometer adopts perforated temperature measurement, the first thermometer is in the preheating section, and the second thermometer is at a certain position away from the furnace outlet. The first thermometer collects the temperature of the specific temperature measurement point and feeds it back to the PLC. The PLC intelligent output ensures that the temperature of the furnace outlet meets the set temperature. Two thermometers, two power supplies, multiple sensors, modular design It constitutes a fully closed-loop temperature control system.

The main process parameters of the intermediate frequency induction heating furnace are as follows:

1. Blank material: 45# steel, etc.

2. The range of blank specifications: diameter Φ70-160, length 120-540. Most of the bars are automatically fed by the washboard type, and the ones that exceed the range of the feeding machine or are fed into the V-shaped groove manually.

3. Heating temperature: 1250℃.

4. Beat: Typical blank Φ120, length 250mm: 44 seconds/piece. Diameter Φ90 and length 400mm: 40 seconds/pieces. Diameter Φ150 and length 300mm: 82 seconds/piece.

5. The heating is stable during normal operation, and the temperature fluctuation between each section of the material is within ±15°C; the axial and radial (core table) ≤100°C.

6. The pressure of the cooling water supply system is greater than 0.5MPa (normal water pressure is greater than 0.4 MPa), and the higher temperature is 60°C. The corresponding hose pressure and interface also need to be proportionally increased to safety standards.
