The equipment needed to cool the IF melting furnace includes two parts: the intermediate frequency power supply and the intermediate frequency furnace.
The intermediate frequency power supply part includes: an intermediate frequency power supply cabinet and a compensation capacitor cabinet.
The intermediate frequency power supply part includes various intermediate frequency power supply devices and electric electric thermal capacitor groups in the intermediate frequency power supply cabinet. The intermediate frequency power supply part is composed of precision electrical components. The diameter of the cooling pipe is relatively thin. In order to prevent the fouling in the pipe from clogging the pipeline and causing the fault, the general intermediate frequency intermediate frequency power supply uses softened water or pure water for cooling, because 70-80% of the electrical equipment failures of the intermediate frequency equipment are Because the water quality is not handled well, the cooling intermediate frequency power supply requires a higher level of cooling water quality.
The intermediate frequency electric furnace body and the intermediate frequency power supply can use the same cooling device or different cooling devices.
The intermediate frequency power supply and the furnace body can be the same cooling device or two independent cooling devices. We recommend a closed-circuit cooling tower for medium-frequency power supplies, and a closed-circuit cooling tower for the furnace. Two sets of complementary effects.
The principle of the medium frequency induction melting furnace closed cooling tower:
The closed cooling tower uses two-stage cooling method: first-stage cooling adopts air-cooling, and wind-cools the cooler coil; the secondary cooling adopts air-cooling and spraying.
At the heart of the fully enclosed cooling unit is a spray-evaporated enclosed cooling tower. There are many heat-dissipating coils inside the cooling tower, and circulating water flows inside the coils without coming into contact with the air. There is a water collecting tray under the cooling tower, and the spraying water is installed inside. The water inlet of the water collecting tray is equipped with a floating ball valve, which can automatically control the water level in the water collecting tray, and the water outlet has a spray water pump. The upper part of the cooling tower is equipped with a water spout and a cooling fan. During operation, the spray pump will pump the water to the upper spout, spray the water onto the outer surface of the coil, and the cooling fan will simultaneously draw air to vaporize the spray water and take away the heat of the circulating water in the coil. This advanced type of cooling device has high heat exchange efficiency and takes up little space.
