water cooling cable of medium frequency melting furnace
Melting furnace water-cooled cable is a special cable used in induction heating systems. It is mainly used in medium frequency smelting furnaces, induction furnaces, medium frequency heating furnaces, diathermy furnaces, forging induction furnaces and other high-power and high-current occasions. It is generally installed in medium frequency Between the power supply and the induction heating coil. This kind of cable is usually composed of multiple copper core wires, covered with a high-temperature-resistant and corrosion-resistant insulation layer, and equipped with a water-cooling system to ensure that the water-cooled cable can operate normally under high current.
Working principle of water-cooled cable for smelting furnace
1. The principle of water-cooled cables in smelting furnaces is to use water-cooling technology to reduce the working temperature of the cable, thereby improving the conductivity and operating efficiency of the cable. Specifically, the structure of the smelting furnace water-cooled cable mainly includes conductors, insulation layers, cooling water channels and outer protective layers. When a large current passes through a conductor, heat is generated, which is absorbed and taken away by the cooling water, thereby reducing the operating temperature of the cable. At the same time, the special design of the cooling water channel allows the cooling water to circulate in the cable to achieve a more effective heat dissipation effect.
2. The principle of water-cooled cables for smelting furnaces also involves heat transfer methods such as heat conduction, convection and radiation. Among them, heat conduction mainly occurs inside the solid, and heat is transferred to the cooling water through convection and radiation. These heat transfer methods cooperate with each other so that the heat inside the cable can be transferred to the outside in time, thereby achieving efficient heat dissipation.
Composition of water-cooled cable for smelting furnace
The smelting furnace water-cooled cable is mainly composed of conductive core, insulation layer, metal sheath and water-cooling system.

2. Insulation layer: The insulation layer of the smelting furnace water-cooled cable is generally made of high-temperature-resistant and corrosion-resistant insulating materials, which can protect the conductive core from erosion by the external environment and ensure the safe operation of the cable.
3 Metal sheath: The metal sheath of the smelting furnace water-cooled cable is generally made of copper, aluminum and other conductive materials, and mainly plays the role of protecting and supporting the cable.
4. Water cooling system: The water cooling system of the smelting furnace water-cooled cable mainly includes water channels and cooling water, which are used to take away the heat generated when the cable is running, reduce the working temperature of the cable, and ensure the normal operation of the cable.
