High frequency induction annealing power supply for wire hot rolling

The hot-rolled wire rod is often called hot-rolled after the steel bar is heated. The hot-rolled steel bar is the finished steel bar that has been hot-rolled and naturally cooled. It is used in the reinforcement of reinforced concrete and prestressed concrete structures, and is one of the most widely used steel varieties in civil engineering. Steel bars with a diameter of 6.5 to 9 mm are mostly rolled into coils. Those with a diameter of 10 to 40 mm are generally straight bars with a length of 6 to 12 meters.

At present, there are many methods for heating hot-rolled steel bars before rolling. The complete set of high-frequency induction annealing power supply has been welcomed by customers once it is promoted. It can also be adjusted, which is very convenient.

Features of high frequency induction annealing power supply

1. The heating speed is fast, and there is basically no scale on the surface of the steel bar.

2. Energy saving, environmental protection, no gas and grid pollution.

3. Safe and reliable, no high voltage, no risk of burns.

4. Power adjustment is flexible and easy to control.

5. The heat loss is very small, the equipment is small in size and occupies a small area, and the hot summer will not cause the workshop to be hotter.

Advantages of high frequency induction annealing power supply

1. The heating speed is faster and the heating is uniform (the speed can be adjusted and controlled)

2. Wide heating, can heat all kinds of metal workpieces (replace the detachable induction coil according to the different working switches)

3. Easy to install, just connect the power supply, induction coil and water inlet and outlet pipes to use. Small size, light weight, easy to use.

4. Fast start-up, heating can be started after water and electricity are applied.

5. The effect is good, the heating is very uniform, the temperature rises quickly, the oxide layer is less, and there is no waste product after annealing.

6. Less power consumption, about 70% less power than old-fashioned tube high-frequency equipment, the smaller the workpiece, the less power consumption.

7. Full protection, with overvoltage, overcurrent, overheating, water shortage and other alarm indications, and automatic control and protection.

8. The power is controllable. When heating, the power can be adjusted to meet the needs of different heating temperatures and speeds.

Other applications of high frequency induction annealing power supply

1. Quenching of various gears, sprockets and shafts.

2. Quenching treatment of machine tool bed guide rails in the machine tool industry

3. Hot heading of various high-strength bolts and nuts

4. Welding of various hard alloy cutter heads and saw blades

5. Welding of various picks, drill bits, drill pipes, coal drill bits, drill bits and other mining accessories.
