Kev ua tau zoo tom qab induction hardening

1. Deg hardness: Lub hardness ntawm lub workpieces raug rau siab thiab nruab nrab zaus induction cua sov nto quenching yog feem ntau 2 mus rau 3 units (HRC) siab tshaj li qub quenching.

2. Kev hnav tsis kam: Kev hnav tsis kam ntawm cov khoom ua haujlwm tom qab lub zog quenching yog siab dua li ntawm cov quenching zoo tib yam. Qhov no feem ntau yog los ntawm kev sib xyaw ua ke ntawm cov nplej zoo martensite hauv txheej tawv, siab carbide dispersion, kuj siab hardness, thiab siab compressive kev nyuaj siab ntawm qhov chaw.

3. Lub zog qaug zog: siab thiab nruab nrab zaus nto quenching zoo heev txhim kho lub zog qaug zog thiab txo qis qhov rhiab heev. Rau workpieces ntawm tib cov ntaub ntawv, qhov tob ntawm lub hardened txheej yog nyob rau hauv ib tug tej yam ntau yam, thiab qaug zog lub zog nce nrog rau qhov nce ntawm qhov tob ntawm hardened txheej, tab sis thaum lub thickness ntawm hardened txheej yog tob heev, lub nto txheej. yog compressive kev ntxhov siab, yog li qhov nce hauv qhov tob ntawm txheej hardened txo qhov qaug zog thiab ua rau lub workpiece. Brittleness nce. General hardened txheej qhov tob δ = (10 ~ 20)% D. ntau haum, qhov twg D. yog qhov zoo txoj kab uas hla ntawm lub workpiece.
