How to reduce the loss of induction melting furnace induction coil and water-cooled cable?
Increasing the diameter of the induction coil and water-cooled cable will greatly reduce its current density, reduce the power loss of the power supply line, and also help reduce the working environment temperature of the induction coil and water cable, and reduce the formation of scale. To
The electric power consumption of the induction coil at t℃ is obtained by the following formula:
W=I2R×10-3=I2P20L/A×[1+α(t-20)]
W in the above formula-power consumption of induction coil, KW;
I―load current, A;
R―The resistivity of the induction coil at 20℃, Ω·m 2.2×10-8;
L―length of induction coil, m;
A―cross-sectional area of induction coil, m2;
P20―The resistivity of copper at 20℃, Ω·mm2·m-1;
α―The temperature coefficient of resistance of electrolytic copper, 4.3×10-3/℃.
