Medium frequency steel shell melting furnace is composed of medium
frequency power supply cabinet, compensation capacitor bank, steel
shell furnace body, magnetic yoke and water-cooled cable, hydraulic
station, tilting furnace control box, etc. Mainly used in smelting
steel, iron, copper, aluminium and alloys, with high melting
efficiency, good power saving effect, uniform metal composition,
less burning loss, fast temperature rise, easy temperature control
and other characteristics, suitable for various metal smelting
occasions, all maintenance points.
Product Advantage
1. Power consumption per ton of iron and steel smelting under
normal working conditions is 550-600KW.h.
2. The power factor is maintained above 0.96 in the whole process
without additional compensation device.
3. Effectively control high-order harmonics, do not interfere with
peripheral electrical equipment, do not pollute the power grid;
4. The frequency range is wide and the optimum resonance state is
always maintained during melting.
5. Zero Voltage Scanning Soft Start mode can start or stop at any
time under any state, and has no impact on the power supply.
6. Rapid smelting, low production cost, low pollution, in line with
national environmental protection requirements;
7. It can be melted directly from the cold furnace, the solution
can be emptied completely, and the variety of melt can be changed
conveniently.
8. Flexible and convenient power regulation, continuous and smooth
regulation, uniform and easy to control temperature, less oxidation
and burning loss, and uniform metal composition;
9. The furnace shell is made of steel or cast aluminum alloy, which
covers a small area. The furnace body is easy to overturn and
topple, and manual, electric and hydraulic methods can be used.
10. Leakage alarm device, timely and effective protection of
personal and equipment safety;
11. The lining ejection mechanism makes the lining replacement fast
and efficient, and improves the production efficiency.
Working principle
The basic principle of induction heating is adopted in the medium
frequency steel shell melting furnace. Induction heating is a
method of heating the load with induction current generated by
electromagnetic induction in the load itself. The law of
electromagnetic induction e=W*-d/dt is also applied.
