How to reduce the loss caused by the water circulation of the induction melting furnace?
Lower the temperature of the water circulation. During the smelting process of the induction melting furnace, the temperature of the induction coil and the water-cooled cable increases, and the resistance of the induction coil and the water-cooled cable will increase with the increase in temperature, resulting in an increase in power consumption. To
The relationship between resistance and temperature change is:
RT=[1+α（T-20)]R20
In the above formula: RT―The resistance value of the coil when the temperature rises to T℃, Ω;
The resistance value of electrolytic copper at R20--20℃, 1.75×10-8Ω;
Α―The temperature coefficient of resistance of electrolytic copper, 4.3×10-3/℃;
