Cold crucible method for artificial gemstones (ZrO2), cold crucible method for sapphire smelting (Al2O3), MgO smelting, smelting and purification of other metal oxides and alloys.
The solid-state high-frequency gemstone melting equipment adopts the cold crucible melting and crystal pulling process. The solid-state high-frequency power supply adopts inverter power regulation technology, which can ensure constant power output control during the melting and crystal pulling processes of the power supply. Gemstones have high quality, stable craftsmanship, and are an ideal choice to replace traditional high energy consuming electronic tube power supplies.
The solid-state high-frequency gemstone melting equipment adopts an AC-DC-AC frequency conversion structure. Adopting IGBT component PWM pulse width modulation chopping voltage regulation mode, the inverter adopts high-power MOSFET to form a full bridge resonant inverter.
Compared with the three-phase fully controlled rectifier circuit controlled by thyristor phase shifting, it has the following advantages:
1. The power factor of the power supply is high, the harmonics are small, and the interference to the power grid is small.
2. Low reactive power loss can reduce user distribution capacity, save investment and electricity consumption.
3. The chopper circuit has high working efficiency, fast power regulation response speed, stable output, and can ensure the quality of smelting.
4. IGBT has the ability to self turn off, which can cut off the power supply in a very short time when a fault occurs, avoiding damage to the inverter components and providing protection.
