Cooling water of medium frequency induction furnace

MF induction furnace is an induction heating equipment. In operation, cooling system is needed to cool the thyristor, capacitor, reactor, water-cooled cable and induction coil, while the cooling medium of intermediate frequency induction furnace is water. Therefore, the cooling water of the medium frequency induction furnace is very important.

Requirements for cooling water quality of medium frequency induction furnace

1. Total hardness of cooling water of medium frequency induction furnace: 2.25-3.5 degrees (CaO content 2.25-3.5mg equivalent)
2. Dissolved solid in cooling water of medium frequency induction furnace ＜ 300mg/l
3. PH value of cooling water of medium frequency induction furnace 7-7.5 alkalinity 60mg / L
4. The conductivity of cooling water of medium frequency induction furnace is less than 500us/cm

Requirements for cooling water system of medium frequency induction furnace

1. The maximum inlet water temperature of cooling water of medium frequency induction furnace is less than 35 ℃
2. The minimum inlet water temperature of cooling water of medium frequency induction furnace is more than 5 ℃
3. The water inlet pressure of cooling water of medium frequency induction furnace is 0.2-0.3mpa
4. The outlet water temperature of cooling water of intermediate frequency induction furnace is less than 55 ℃

Specific requirements for cooling water cooling components of medium frequency induction furnace

1. Cooling water system of induction coil and capacitor bank of medium frequency induction furnace

The cooling water pressure of medium frequency induction furnace shall be kept at 0.2-0.3mpa, the water temperature shall be kept at the inlet temperature of 20-35 ℃, the outlet water temperature shall be lower than 55 ℃, and condensation will occur when the temperature of cooling water is too low, and the cooling capacity will be lost if the water temperature is more than 55 ℃. In order to save water, the medium frequency electric furnace usually adopts the circulating cooling system.

2. Cooling system of SCR converter in medium frequency induction furnace

The cooling water of SCR transistor in if induction furnace shall meet the following conditions: the cooling water pressure shall be kept at 0.15Mpa stably, the water quality shall be softened, the hardness shall be less than P8, and the resistance shall be 20K Ω Above, the insoluble matter in water is less than 0.03mg/l.

In order to ensure the safety of the use of intermediate frequency induction furnace, the cooling water system shall be equipped with centralized water supply and return water. The water circuit shall be equipped with water pressure alarm device and water stop alarm device to prevent accidents of medium frequency electric furnace equipment caused by insufficient water pressure or water cut-off.
