Medium Frequency Furnace

15 Ton Medium Frequency Induction Electric Furnace

I. Working Principles and Main technical parameters

II.operating conditions:

(1) Ambient temperature: +5°C ~ 40°C;

(2) Relative humidity shall not exceed 90% (25°C);

(3) Altitude shall not 1,000m;

(4) Free of conductive dust, explosive gas and corrosive gas around the furnace;

(5) No evident vibration or bumps;

(6) Inlet water temperature: +5°C ~35°C; water quality: hardness shall not exceed 10-degree; total solid content shall not exceed 300mg/L, PH: 7-8.5;

(7) 3-phase power-supply voltage fluctuation shall not exceed ± 5%.

III.Electrical Feature:
1. Digital CMOS chip (U. S. ASIC-2-12), with the highest degree of integration at home, is used in control circuit, the overall machine controlled through one single panel.
2. Frequency-sweep zero voltage start, high success rate, no shock;
3. Automatic resistance adjustment, permanent power output, 10-20% energy saved in comparison with domestic traditional machine of the type;
4. Auto phase sequence adaptation, free of synchronization;
5. Good performance in reload staring, auto recovery;
6. Highly integrated in controlling circuit, free of use of high-rate starter and relay loop, fairly low failure rate;
7. Wholly digital design, strong in anti-interference, no temperature shift when in continuous working;
8. Multi-protection functions (for over current, over voltage, insufficient water pressure, power failure, or phase absence), and mishandling will not cause damage to machine.

IV.Furnace Features:
1) 1,600 centigrade
2) SCR static frequency conversion adopted as IF power supply for induction heating
3) Pouring action driven mechanically or oil hydraulic
4) High efficiency, little noise, easy operation and maintenance
5) Usage: Refining ferrous metals, smelting nonferrous and precious metals, such as Cu and Al
