Electromagnetic heaters can be used for metal smelting, especially for applications such as surface heating, melting, and quenching of metals. Compared to traditional gas, resistance, or flame heating, electromagnetic heating has the advantages of fast heating speed, uniform heating, and high control accuracy.

In the process of metal smelting, electromagnetic heaters can generate eddy currents and Joule heat inside the metal by adjusting electromagnetic field parameters, thereby causing thermal effects. This heating method can quickly increase the metal temperature, improve the heating efficiency of the furnace, and during the heating process, the metal surface will not come into contact with high-temperature gases, thus avoiding the problem of oxidation and burning.

In addition, electromagnetic heaters can also be used in the process of metal quenching and tempering. By heating the required area, the metal can reach the toughness zone in a short period of time, thus achieving the ideal quenching effect. At the same time, it reduces the heat affected zone of the metal and avoids problems such as cracks and stress.

In short, electromagnetic heaters are widely used in the fields of metal smelting and processing, and have good application effects in industries such as steel, non-ferrous metals, ceramics, etc., with high safety, environmental protection, energy conservation, and processing efficiency.
