Iron and steel IGBT induction melting furnace equipment was developed for steel smelting. It adopts all-solid-state IGBT frequency conversion and power regulation. The equipment has designed a full range of protection functions such as over-current protection, under-current protection, over-temperature protection, over-voltage protection, and short-circuit. Protection and phase loss protection greatly increase the reliability of the equipment.
Compared with the traditional flame smelting process, induction heating smelting has obvious advantages such as energy saving, environmental protection and safety.
Induction heating smelting is more efficient than flame heating smelting. It has a high output per unit time. The heating efficiency is 30%~50% higher than that of flame heating, and the heating efficiency is high. At the same time, it can also effectively reduce the low burn of the oxide scale on the metal surface, saving material and The cost, especially for the heating of precious metals is even more important. For example, under normal circumstances, the heating of metal parts by thermoforming, the burning rate of inductively heated metal is about 0.5%, and the burning of metal heated by flame furnace is about 1%~3%, which means that induction heating saves 2% than flame heating. %about.
One of the most outstanding advantages of induction heating and flame heating is reflected in the fact that induction heating does not produce an open flame and eliminates the possibility of dangerous events such as fire and explosion. The safety is greatly improved. At the same time, it does not produce exhaust gases and dust such as carbon monoxide, carbon dioxide, and sulfur oxides. The external radiation has low heat, low noise, and the working environment can be purified and the health level can be guaranteed.
Steel shell medium frequency smelting furnace - 3 tons
Electrical efficiency: 62% Thermal efficiency: 75% Conversion loss: 3% Transmission loss: 5%
Transmission loss: The losses caused by cables and busbars supplied by the variable frequency power supply to the load are about 2% to 7%.
Conversion loss: The loss of the converter components, filter inductors, converter inductors, and compensation capacitors in the power supply cabinet is generally between 2% and 5%.
Mainly used for smelting temperature and heat preservation of cast iron, stainless steel, alloy steel, non-ferrous metals (such as copper, aluminum), precious metals (such as gold, silver) carbon steel, alloy steel, and special steel, and can be operated in double operation with the blast furnace.
