Dab tsi yog cov yam ntxwv ntawm lub sijhawm melting ntawm cov hlau nqi ntawm induction melting rauv?

① Tus nqi hlau ntawm lub induction melting rauv maj mam yaj, thiab cov hlau molten yog maj mam tsim. Qhov chaw txheeb ze ntawm cov hlau molten yog qhov loj, thiab lub pas dej molten yog qhov ntiav, uas yog qhov zoo heev rau degassing thiab tshem tawm cov tsis yog xim hlau inclusions. Cov kev tshem tawm suav nrog rau 70% ntawm tag nrho cov koom nrog. saum toj no;

② Feem ntau cov pa roj tuaj yeem raug tshem tawm thaum lub sijhawm yaj. Hydrogen tuaj yeem tshem tawm 70-80%, nitrogen tuaj yeem tshem tawm 60-70%, thiab oxygen tuaj yeem tshem tawm 30-40%;

③ Cov nqi hlau tso tawm cov roj ntau thaum lub sijhawm cua sov thiab melting txheej txheem, uas txo qhov nqus tsev kawm ntawv;

④ Nyob rau hauv cov txheej txheem melting ntawm tus nqi hlau, qhov kub ntawm cov khoom siv hlau nyob ib ncig ntawm cov phab ntsa crucible yog qhov siab tshaj plaws (tshwj xeeb yog qhov nruab nrab thiab qis), thiab yog thawj zaug yaj. Vim muaj kev sib xyaw ua ke ntawm eddy tam sim no kub, radiant tshav kub, thiab conduction tshav kub, tag nrho cov nqi hlau maj mam txais, thiab cov hlau molten Qhov kub yog ruaj khov.
