Five, what advantages does 1Tone belt two intermediate frequency furnaces have ?

1. The rectifier circuit is always in the all-on state, and the boost power is realized by adjusting the current of the series inverter bridge. Therefore, the entire operation process (including low power, medium power, high power) can ensure that the equipment is always in a high efficiency stage. 20% less than normal equipment

2 , equipment power factor  9 6 % . The higher harmonics meet the standard without interference to the grid. There is no need for reactive power compensation devices and harmonic elimination devices.

3 , full load starting success rate of 100% . 2 sets of electric furnace while having the ability to mass production.

4 , an intermediate frequency power supply can work with 2 furnaces at the same time, the power can be distributed freely, no need to change the furnace switch equipment. The high utilization of the transformer can save half of the transformer capacity.

5 , constant power output, if the grid voltage rises or decreases, the power output can be kept constant, and the full power output can be ensured.

6. It can be kept warm or heated at an accurate temperature when it needs to be melted without interruption . The two electric furnaces can be cast at the same time, and can also be continuously supplied with molten steel.

Six, 1Tone belt two intermediate frequency furnace application

The 1T one-to-two intermediate frequency furnace is suitable for casting large-scale workpieces that require two furnaces of steel at the same time. It is suitable for working with two furnaces at the same time, and one working mode of melting another. Applicable to the casting production line requires continuous uninterrupted discharge of molten steel and sand mold manufacturing cycle.

Seven, series 1T one belt two intermediate frequency furnace technical features :

one belt two intermediate frequency electric furnace adopts " series inverter thyristor intermediate frequency power supply technology " , adopts thyristor full control rectifier electric furnace, but does not need it to regulate voltage, only use it to realize soft start and fault as electronic switch, quickly cut off power supply, normal production When the thyristor is always in a fully conducting state, the grid supply has a high power factor and reduces harmonic interference. The rectification control circuit adopts a digital shifting trigger circuit. The digital shifting trigger circuit has the advantages of good repeatability, good stability, good symmetry, strong anti-interference ability, convenient debugging, etc., and long-distance control can be realized if the digital quantity is given.

Eight, the reason to buy 1Tone belt two intermediate frequency furnace

  8.1 high efficiency

The series inverter uses a half-bridge circuit, the number of main circuit components is relatively reduced, and has a high power factor, so there is higher power.

Good start-up characteristics, can be started at random under full load and heavy load conditions, and the startup success rate is up to 100% . Improve power factor, to ensure that in any power power factor of 96%.

Constant power output, power output is controlled by constant. During the melting process, when the load and temperature change, the load is always full power output, thus shortening the melting time.

8.2 with perfect protection and health monitoring system

Such as: using the sensor to the incoming current, voltage, circuit current, voltage to take the signal, to the double-closed digital circuit for current limiting, voltage limiting, excessive overvoltage and repeated protection, water temperature and water pressure protection. Both KK thyristors and KP thyristors have self-shutdown time protection.

8.3 complete detection system

For the inverter, the working temperature of the filter capacitor is monitored by the temperature switch table. Once the temperature of the cooling water exceeds the set value or a waterway fault occurs, an alarm is issued and the power is turned off. There is water pressure and electric control for the power supply cooling water input, and the cooling water output has a temperature switch table to monitor the undervoltage. The over temperature will give an alarm and cut off the power.

Nine, the latest 1T one belt two intermediate frequency furnace features introduced by our company

First, the use occasion: suitable for casting large workpieces need to produce two furnace steel at the same time. Applicable to one power supply, two furnaces work at the same time, one smelting another insulation mode. Applicable to the casting production line requires continuous uninterrupted discharge of molten steel and sand mold manufacturing cycle.

Second, compared with the traditional parallel: can work in the detuned state, adjust the output power by frequency modulation. Inverter thyristors are not burned in the event of any failure. Can adapt to the working mode of heavy load start-up operation. The thyristor of the rectifier bridge in the whole process of the equipment operation is always in the fully open state, so the power factor of the whole smelting process reaches 0.96 or more. Improve overall operating efficiency and save operating costs. The resonant tank current is close to the DC current, so the loss on the overall line is small and the overall efficiency is improved. Eliminating the work caused by frequent replacement of water-cooled cables or furnace switches reduces the labor intensity of workers.
