A band two induction melting furnace is an induction melting furnace one, its structure is a medium frequency power source with two furnaces simultaneously, an arbitrary power distribution, one for melting, holding for a uninterrupted smelting requires At the same time, it is possible to carry out heat preservation, temperature rise, quenching and tempering at an accurate temperature to maximize production. Good start-up characteristics, can be started at random under full load and heavy load conditions. Increase the power factor and ensure a power factor of 95% at any power . The constant power output is controlled by constant power output. During the melting process, when the load and temperature change, the load is always full power output, which can shorten the melting time. Accordingly, a band two induction melting furnace series half-bridge inverter circuit, since the number of main circuit components is relatively reduced, and a high power factor, and therefore a higher power. Therefore, we need to understand the precautions and technical features of the use, the following is for everyone to introduce.

A , one with two induction melting furnace Precautions

1. Check that all components are in good condition;

2. Check that all fasteners are in good condition;

3. Check if all the wires are disconnected and whether the solder joints are desoldered;

4. Check if the connection in the installation is correct.

5. Check the main circuit with a multimeter, and control the insulation of the casing and the insulation between the phases;

6. Check if the control plug-in is placed correctly.

7. Open the inlet valve and adjust the water pressure to 0.1 ~ 0.2Mpa to check whether there is leakage in each waterway;

8. Strictly check the phase sequence, the smelting furnace correspondingly advances the intermediate frequency power supply phase by 120 ° degrees, and the holding furnace lags the intermediate frequency power supply phase by 120 ° degrees;

9. Press the control and power switch, the power indicator of each control board should be on;

10 , use the oscilloscope to check the rectification and inverter trigger pulses should be normal;

11. Trigger the protection thyristor, and the corresponding protection indicator light is on;

12 , put the power potentiometer into the 0 position, the control board is dialed out, check the relay action should be normal.

B , one with two induction melting furnace technical features

A band two induction melting furnace using a "series thyristor inverter frequency power supply technology", although use of an electric furnace controlled rectifier SCR, but it is not the regulator, it is only when the soft-start failure and as an electronic switch, quick disconnect Power supply, the thyristor is always in full conduction state during normal operation, so that the power supply of the grid 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.

In summary, a band two induction melting furnace is a melting furnace with a higher power, so in order to make it possible to get the most high-power play, so we must pay attention to some of its more than Note the use of technology and its various The characteristics, in order to effectively play the maximum function of its melting, combined with effective protection of the induction furnace time limit.
