    (1) Power supply characteristics:

    The company's power supply uses the most advanced electronic circuit control, with overvoltage, overcurrent, voltage limiting, current limiting, phase loss, under voltage, under water pressure, phase sequence automatic identification, cooling water temperature over limit alarm protection and many other protections。 Features。 Power factor automatic adjustment function。 It can realize the full supply of power to the furnace body regardless of the change of the furnace condition from the cold charge to the whole cycle of casting, so that the amount of metal per kWh is the most, and the heating time of the same power is the shortest, thus increasing the profit of the manufacturer。 Increased labor productivity。

    The control line dedicated integrated box is completely isolated from the high pressure area to keep the control room clean and cool。 Greatly improve control board life and system reliability。

    High-power converter devices of international and domestic well-known manufacturers are preferred, and they are operated at 50% of rated capacity, thus having a design safety factor of 100%, increasing the reliability of the entire system.

    With a large air-cooled copper row, more energy is used for heating than the water-cooled copper row, which increases efficiency and requires no maintenance。

    The power supply starts with zero-voltage sweeping, no impact, and can be reliably dynamic in the state of no-load, heavy-duty, cold steel, etc. It is stable and reliable, and has no trouble-free time and is convenient for maintenance.

    (2) Heating characteristics:

    The heating speed is fast, the heating temperature is uniform, the oxidation loss is small, and the metal component is uniform.

    It can be directly heated from a cold furnace and is easy to change.

    Exquisite coil design, high-quality thick-walled copper tube, through the reasonable choice of the inter-turn distance of the induction coil, the induction coil has the highest conversion efficiency, the smallest resistance, more energy can be used for melting, heating, high strength, the coil is not easy to occur due to arc Damage caused by expansion force.

    The solid coil support system allows each coil to be securely locked, eliminating the possibility of a short circuit between turns。

    Overcoming the driving force of electromagnetic force, greatly extending the service life of the lining。
