Background
At present, a power frequency cored induction furnace is generally used for casting zinc ingots in the electrolytic zinc industry. Industrial frequency channel induction furnaces are usually equipped with 2-3 inductors. The service life of an induction furnace body is generally more than 10 years, the service life of an inductor is relatively short, main factors influencing the service life of the inductor comprise the advantages and disadvantages of ramming furnace materials, zinc leakage of an installation position and the inductor, cracks can be generated on the high-quality inductor furnace materials, only the differences of more and less, width and narrow, speed and slow are generated, the installation position of the inductor is fixed when the furnace body is designed, and the inductor cannot be changed in the using process. Therefore, the inductor has a good service life of more than 2 years, a bad service life of only a few days, and a normal service life of 1 year.
The zinc leakage of the inductor generally means that zinc liquid in a zinc ring penetrates through furnace burden, and hot zinc liquid flows out along a crack to burn an insulating layer to cause short circuit and burnout of a coil. Particularly, when zinc is melted by adopting a zinc skin of zinc electrolysis by a chloroammonia method, the inductor is damaged more frequently because the zinc skin contains more organic matters. A large amount of black matters are accumulated in a damaged inductor melting groove, main components of the black matters are zinc oxide and carbon deposit through analysis, the zinc oxide and the carbon deposit are accumulated on the wall of the melting groove, the melting groove is reduced, the flowing resistance of zinc liquid is increased, the over-temperature condition of the melting groove is caused, the zinc liquid seeps out from a furnace charge crack, and zinc leakage of an inductor is caused.
