What are the characteristics of the melting period of the metal charge of the induction melting furnace?

① Mtengo wachitsulo wa chowotcha kutentha gradually melts, and the molten steel is gradually formed. The relative surface area of the molten steel is large, and the molten pool is relatively shallow, which is very conducive to degassing and removal of non-metallic inclusions. The removed inclusions account for 70% of the total inclusions. above;

② Mipweya yambiri imatha kuchotsedwa panthawi yosungunuka. Hydrogen imatha kuchotsa 70-80%, nayitrogeni imatha kuchotsa 60-70%, ndipo mpweya umatha kuchotsa 30-40%;

③ Chitsulo chachitsulo chimatulutsa mpweya wochuluka panthawi yotentha ndi kusungunuka, zomwe zimachepetsa kutentha kwa mpweya;

④ Pakusungunuka kwazitsulo zachitsulo, kutentha kwazitsulo zozungulira khoma la crucible ndipamwamba kwambiri (makamaka gawo lapakati ndi lapansi), ndipo ndilo loyamba kusungunuka. Chifukwa cha kuphatikizika kwa kutentha kwamakono kwa eddy, kutentha kowala, ndi kutentha kwa conduction, chitsulo chonsecho chimamira pang’onopang’ono, ndi chitsulo chosungunuka Kutentha kumakhala kokhazikika.
