Medium frequency melting furnace one tow two scheme

Author : Hongteng Time: 2022-11-11

There are many ways to use intermediate frequency smelting. Today, the editor of Red Teng will introduce one of the most common schemes: one drag two.

From the name understanding, one tow two medium frequency melting furnace is a power supply with two stoves working at the same time. The power of the power supply can be arbitrarily distributed, one furnace melting, the other heat preservation, the melting process is uninterrupted. When necessary, it can be insulated, heated and tempered at the exact temperature to maximize the production.

Technical Features

One tow two intermediate frequency furnace adopts special thyristor control to control the current. When working normally, the thyristor is always on, so that the power supply has a high power factor, but also reduce the harmonic interference.

The thyristor current control circuit has the advantages of good repeatability, good stability, good symmetry, strong anti-interference ability, convenient debugging and so on. It can also realize remote control.

Inverter adopts half bridge circuit, can reduce the number of main circuit components, and has a high power factor. At the same time, the circuit is guaranteed to have good starting ability. Whether in full load or heavy load state, it can be started at will, and the success rate of starting is up to 95%.

Inverter has a complete detection system, the working temperature of the capacitor is monitored by the temperature switch table, once the cooling water temperature exceeds the set value or the water fault will send an alarm, and cut off the power supply.

At the same time, we also use SCR in the original part of the power supply.

SCR can ensure the constant power output of the circuit, in the process of melting, load and temperature changes, the load is always full power output, thus shortening the melting time.

Both KK SCR and KP SCR have self-shutdown time protection.

Regarding the use of power supply safety, there will be a sophisticated protection mechanism. Use the sensor to take signals for incoming line current, voltage, trough current and voltage, and carry out current limiting, voltage limiting and repeated protection of excess and overvoltage for the circuit.

The input of cooling water in the power supply is controlled by hydraulic pressure and electrical control, and the output of cooling water is monitored by temperature switch meter. Overtemperature will send an alarm and cut off the power supply.
