The reactive power consumption of induction smelting furnace is mainly the copper loss caused by induction coil and water cable during the operation of the furnace, and its unit resistance has a great influence on the copper loss. At present, in order to reduce the cost of some electric furnace manufacturers, the copper raw materials of induction coil are mostly purple copper with low price and high resistance value instead of No.1 electrolytic copper with low resistance value, which leads to high resistance of induction coil and water cable and relatively large power loss per unit time.

High quality and high purity copper tube has bright surface color, low resistance and good conductivity. However, inferior copper is not entirely made of copper materials. The copper tube is blackened and hard. Due to many impurities, it can not bear large current and has high heat value when electrified. Therefore, it should be distinguished when selecting materials.
