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.
