Dab tsi yog qhov txawv ntawm cov high quenching thiab nruab nrab zaus quenching?

Lub hauv paus ntsiab lus ua haujlwm ntawm high-frequency quenching thiab intermediate-frequency quenching yog tib yam li cov cua sov induction: uas yog, lub workpiece yog muab tso rau hauv inductor, thiab inductor feem ntau yog ib tug hollow tooj liab raj inputting intermediate zaus los yog high zaus alternating tam sim no. (1000-300000Hz lossis siab dua). Lub alternating magnetic teb generates ib tug induced tam sim no ntawm tib zaus nyob rau hauv lub workpiece. Kev faib tawm ntawm qhov induced tam sim no nyob rau hauv lub workpiece yog tsis sib npaug, nws muaj zog nyob rau saum npoo, tab sis tsis muaj zog heev nyob rau hauv sab hauv, thiab nws yog ze rau 0 nyob rau hauv qhov chaw. Cov nyhuv ntawm daim tawv nqaij no yog siv. , qhov chaw ntawm lub workpiece tuaj yeem ua kom sov sai, qhov kub ntawm qhov kub nce mus rau 800-1000 ℃ hauv ob peb feeb, thiab qhov kub ntawm qhov tseem ceeb yog me me.

Txawm li cas los xij, thaum lub sij hawm ua cua sov, qhov kev faib tawm ntawm qhov induced tam sim no nyob rau hauv lub workpiece yog unevenly, thiab cov cua kub nyhuv uas ua los ntawm txawv tam sim no frequencies kuj txawv. Tom qab ntawd, qhov sib txawv ntawm high-frequency quenching thiab intermediate-frequency quenching los:

1. High zaus quenching

Tam sim no zaus ntawm 100 thiab 500 kHz

Ntiav ntiav txheej (1.5 ~ 2 hli)

Qhov zoo tom qab lub siab zaus quenching: siab hardness, lub workpiece tsis yooj yim rau oxidized, lub deformation yog me me, quenching zoo yog zoo, thiab ntau lawm efficiency yog siab.

High-frequency quenching yog haum rau qhov chaw uas ua hauj lwm nyob rau hauv kev sib txhuam tej yam kev mob, xws li feem ntau me zog thiab shafts (cov khoom siv yog 45 # steel, 40Cr)

2. Nruab nrab zaus quenching

Tam sim no zaus yog 500 ~ 10000 Hz

Lub hardened txheej yog tob (3 ~ 5mm)

Intermediate zaus quenching yog tsim rau cov khoom uas raug twisting thiab siab loads, xws li crankshafts, loj zog, sib tsoo tshuab spindles, thiab lwm yam. (cov ntaub ntawv siv yog 45 # steel, 40Cr, 9Mn2V thiab ductile graphite.

Nyob rau hauv luv luv, ib qho kev sib txawv ntawm high-frequency quenching thiab intermediate-frequency quenching yog qhov txawv ntawm cov cua sov thickness. High-frequency quenching tuaj yeem ua kom tawv tawv hauv lub sijhawm luv luv, cov qauv siv lead ua zoo heev, thiab cov qauv deformation me me. Ua me me.
