Seven Methods for Energy Saving of Medium Frequency Induction Furnace

Medium frequency induction melting furnaces are widely used in the metal smelting industry. It has the advantages of fast heating speed, high melting efficiency, low energy consumption, and simple operation. So, what are the ways to save energy when using a medium frequency induction melting furnace?

The energy-saving work of the medium frequency induction melting furnace is a systematic project, and one or two energy-saving measures alone are not enough. System engineering requires the application of a variety of technical measures, the organic combination of technical energy conservation and management energy conservation, and the comprehensive control of raw materials, equipment, processes, and management in order to achieve good energy-saving effects. The following are several effective energy-saving measures for medium frequency induction melting furnaces.

1. Appropriate size and thickness of furnace charge, light and thin steel scrap can be packaged, a returned charge should be cleaned before use, scrap steel should be descaled, all charges should be preheated, and the ingredients should be accurate.

2. The higher the bulk density of the furnace material in the lower part of the crucible, the better, and the heating efficiency will be improved accordingly. The cold material should be added continuously for preheating and avoiding the phenomenon of melting a small amount of molten iron.

3. Reasonable power supply system and front-of-furnace operation technology. In the beginning, about 60% of the power is supplied. After the current impact stops, the power is quickly increased to a maximum value to accelerate the melting of the furnace charge.

4. Control the high-temperature refining and tapping temperature. After each tapping, there should be a remaining part of the molten iron in the furnace, which is convenient for melting and rapid melting.

5. Try to adopt the smelting operation mode of continuous operation.

6. Shorten the time of no-load auxiliary operations, such as feeding, slag removal, temperature measurement, sampling, waiting for testing, adjusting chemical composition, waiting for pouring, etc. The shorter the time, the higher the production efficiency and the lower the energy consumption.

7. Pay attention to maintaining the normal operation of the intermediate frequency power supply unit, furnace body, cooling water system, etc., reduce the failure rate, reduce the number of furnace shutdowns in the middle, save energy consumption, and ensure smooth production.

The above is the energy-saving method of the intermediate frequency induction melting furnace introduced by Luoyang Hongteng. Of course, improving the energy-saving effect of intermediate-frequency induction melting furnaces requires the cooperation of manufacturers and users. In addition, it can be used in conjunction with dust removal and purification equipment, focusing on water recycling, using energy-saving raw materials, and improving energy-saving awareness are also very critical measures.
