Induction furnace steelmaking EAF characteristics compared to
    Induction Furnace is the use of alternating current induction effect, so that the metal charge in the crucible itself emit heat, which melts and further reacting a superheated liquid metal smelting process. Induction furnace according to the configuration into a coreless and cored two. Intermediate frequency induction melting  capacitors are important core.
    Since the induction furnace sensor is a big inductance, coupled with the magnetic flux is closed through the air, so the induction furnace reactive power is quite large, the power factor is very low, generally only 0.10-0.11, it is necessary to use the appropriate capacitor and inductor in parallel to compensate for reactive power to improve power factor.
    Induction furnace characteristics (compared to EAF): 1 heating speed: the heat generated inside the liquid steel in the charge or direct heating, faster. 2. oxidation burning lighter, less gas absorption: no arc ultra-high temperature, the lower element burnout rate. No arc electron impact, reducing sources of liquid steel gas. 3. slag chemically active weak: liquid steel slag is heated above contact with the atmosphere, lower temperature, chemically inactive, regardless of the role in the smelting process.
