Technical characteristics and advantages of one-to-two medium frequency smelting furnace
One-to-two medium frequency melting furnace , as its name implies, is one power supply with two furnaces working at the same time, power is distributed at will, one for smelting, one for heat preservation, continuous melting, when needed, it can be kept at an accurate temperature, heating up, tempering, etc., maximum Limit increase in production. Technical characteristics The one-to-two medium frequency furnace adopts the "series inverter thyristor medium frequency power supply technology". Although the thyristor fully controlled rectification furnace is used, it does not use it for voltage regulation. It only uses it to achieve a soft start and act as an electronic switch in the event of a fault to quickly cut off the power supply. , In normal operation, the thyristor is always in the fully-on state, so that the power supply of the grid has a high power factor and reduces harmonic interference. The rectifier control circuit adopts a digital shift trigger circuit. The ...
