Yuav ua li cas txog qhov ua tau zoo ntawm qhov nruab nrab zaus induction cua sov saum npoo tawv
Yuav ua li cas txog qhov ua tau zoo ntawm nruab nrab zaus induction cua sov ua kom tawv tawv?
1. Cov tawv tawv: Cov tawv tawv ntawm cov khoom ua haujlwm uas ua rau saum npoo av los ntawm qhov kub thiab qhov nruab nrab induction cua sov feem ntau yog 2 txog 3 chav nyob (HRC) siab dua li quenching.
2. Hnav tsis kam: Hnav tsis kam ntawm cov khoom ua haujlwm tom qab siv hluav taws xob ntau dua li qhov ua kom zoo li qub. Qhov no feem ntau yog los ntawm kev sib xyaw ntawm cov nplej me me martensite hauv txheej tawv, ua kom siab carbide tawg, siab tawv, thiab siab saum npoo av.
3. Lub zog qaug zog: siab thiab nruab nrab zaus ntu quenching zoo heev txhim kho lub zog qaug zog thiab txo qis kev nkag siab. Rau qhov ua haujlwm ntawm cov khoom siv tib yam, qhov tob ntawm txheej tawv tawv yog nyob hauv qee yam. Raws li qhov tob ntawm txheej tawv tawv nce ntxiv, lub zog qaug zog nce ntxiv, tab sis thaum qhov tob ntawm txheej tawv tawv dhau lawm, txheej saum npoo yog nrawm, yog li lub zog qaug zog txo thaum qhov tob ntawm txheej tawv tawv nce. Nce brittleness. Feem ntau, qhov tob ntawm txheej tawv tawv yog δ = (10 ~ 20)%D. Qhov tsim nyog dua, qhov D. Yog txoj kab uas hla ntawm cov haujlwm
