Copper metal intermediate frequency melting furnace
Intermediate frequency power supply adopts IGBT power devices and dual-regulation variable current control technology based on parallel resonance. In this technology, power and frequency are independently controlled. IGBT switching devices and amorphous inductors are used to form a high-frequency chopper circuit to regulate power. IGBT parallel resonance and automatic frequency tracking technology are used to obtain accurate soft switching control of the inverter process. The reliability of the equipment under high power has been greatly improved, which has enabled the equipment to be developed in the high power field, and the 100% equipment temporary load rate has been achieved.
Copper metal intermediate frequency melting furnace-product advantage
1. The heating is uniform, ensuring that the temperature difference between the core surface of the heated workpiece is small. The temperature can be accurately controlled through the temperature control system to ensure the repeatability of the product.
2. All-round protection functions such as over-current protection, under-water protection, over-heat protection, over-voltage protection, short-circuit protection, phase loss protection, etc. are designed in the equipment, which is greater than increasing the reliability of the equipment and facilitating the maintenance of the equipment.
3, the device has a variety of display functions such as frequency display, current display, voltage display, power display, to make the equipment working conditions intuitive, more guidance for the design of the induction coil and capacitance adjustment
4, ultra-small size, light weight, movable, covering less than 1 square meter
5, low energy consumption, no pollution, high heating efficiency, compared with other heating methods, effectively reduce energy consumption, high labor productivity, no pollution, equipment meets environmental protection requirements.
6. The maximum heating capacity of each melting furnace. In the cold furnace, the melting time of each furnace is 40-50 minutes. In the hot furnace, the melting time of each furnace is 20--30 minutes.
