250 kg induction melting furnace standard

( 1 ) Power characteristics:

The company's intermediate frequency power supply uses the most advanced electronic circuit control at present, with overvoltage, overcurrent, voltage limiting, current limiting, phase loss, undervoltage, underwater pressure, phase sequence automatic identification, cooling water temperature over-limit alarm protection, etc. Protective function. Automatic power factor adjustment. It can achieve the full power to the furnace body automatically during the whole cycle from the cold charge to the casting, regardless of the changes in the furnace conditions, so that the maximum amount of metal is smelted per degree, and the heating time is the shortest at the same power, which increases the profit of the manufacturer. Increased labor productivity.

The control circuit special integrated box is completely isolated from the high-voltage area to keep the control room clean and cool. Greatly improve the life of the control circuit board and system reliability.

The high-power converters of well-known international and domestic manufacturers are selected and they are operated at 50% of the rated capacity. Therefore, they have a 100% design safety factor and increase the reliability of the entire system.

Compared with water-cooled copper bar, it uses wider air to cool the copper bar. It has more energy for heating, and its efficiency is increased, and no maintenance is needed.

The power supply starts with zero-voltage sweep frequency, without impact, and can reliably start up in no-load, heavy-load, cold-steel and other states, stable and reliable, long trouble-free time, and convenient maintenance.

( 2 ) Heating characteristics:

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

It can be heated directly from the cold furnace, and it is convenient to change the variety.

Superb coil design, high-quality thick-walled copper tube, through reasonable selection 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 smelting, heating, high strength, and the coil is not prone to arcing And expansion force.

The solid coil support system makes each turn of the coil firmly locked, eliminating the possibility of short-circuits between turns.

Overcome the driving force of electromagnetic force and greatly extend the life of the furnace lining.

In addition, the company can also provide users with special rectifiers S9 and S11 series for induction melting furnace .

Capacity: 500KVA ~ 4000KVA 35KV or 10KV / 380V , 660V , 1250V .
