1. Using the principle of electromagnetic induction to heat the material, the heating speed is fast, the melting period is short and the thermal efficiency is high;
2. The heating energy is clean, and there is no large amount of flame and gas released during the heating process, so the pollution is small and the investment in environmental protection equipment is reduced;
3. Due to the development of electronic technology, frequency conversion equipment has become more compact and portable, easy to control, easy to control the power of smelting process or realize the automation of smelting process;
4. It is convenient to change the types of molten metal materials, especially suitable for small batch and multi-variety casting units;
Because of the good performance of the above equipment, it has been widely used in casting production.
With the development of the times and the progress of science and technology, the computer network has developed rapidly, and the security
