Qhov txawv ntawm high zaus thiab nruab nrab zaus quenching nyob rau hauv cov khoom siv hluav taws xob ntau zaus

(1) High-frequency quenching muaj ib tug ntiav hardened txheej (1.5 ~ 2mm), siab hardness, lub workpiece yog tsis yooj yim rau oxidize, muaj me me deformation, zoo quenching zoo thiab high efficiency efficiency, thiab yog haum rau qhov chaw ua hauj lwm nyob rau hauv kev sib txhuam. tej yam kev mob, xws li feem ntau me me zog, Ncej (cov khoom siv yog 45 # steel, 40Cr);

(2) Lub hardened txheej ntawm intermediate zaus quenching yog sib sib zog nqus (3 ~ 5mm), uas yog haum 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 hlau).

(3) High zaus induction cua sov 200 ~ 1000kHz 0.5 ~ 2.5 Me me thiab nruab nrab modulus iav thiab ncej qhov nruab nrab thiab me me.

(4) Nruab nrab zaus induction cua sov 2500 ~ 8000Hz 2 ~ 10 Cov ncej loj thiab loj thiab nruab nrab modulus iav.

Raws li qhov tam sim no zaus, induction cua sov nto quenching yuav muab faib ua: siab zaus quenching 100-1000kHz. Intermediate zaus quenching 1-10kHz. Fais fab zaus quenching 50Hz.

1. Lub hardness ntawm txheej saum npoo yog 2-3HRC siab tshaj qhov zoo tib yam quenching, thiab nws muaj qis brittleness, qaug zog, thiab tej yam toughness. Feem ntau, lub workpiece tuaj yeem nce 20-30%.

2. Lub deformation yog me me, thiab qhov tob ntawm quenching txheej yog yooj yim los tswj.

3. Cov hlau tsis tshua muaj zog tuaj yeem siv tau, kev ua haujlwm yooj yim kom paub txog tshuab thiab automation, cov khoom tsim tau siab, qhov ntau dua tam sim no, lub thinner txheej hardenable.

(5) Cov khoom siv ntau zaus quenching feem ntau yog 1-2 hli, qhov nruab nrab zaus quenching feem ntau yog 3-5 hli, thiab lub zog zaus quenching tuaj yeem ncav cuag> = 10-15mm.

(6) High-frequency induction cua sov: tam sim no zaus yog 100-500 kHz (kHz), thiab qhov zoo hardening qhov tob yog 0.5-2 hli (mm). Nws yog tsuas yog siv rau me me thiab nruab nrab qhov chaw uas yuav tsum tau ib tug nyias hardened txheej, xws li me me Modular zog, me me thiab nruab nrab shafts, thiab lwm yam.

(7) Qhov nruab nrab zaus induction cua sov: qhov zaus tam sim no yog 500 txog 10000 Hz (Hz), thiab qhov zoo hardening qhov tob yog 2 mus rau 10 hli (mm). Nws yog tsuas yog siv rau qhov chaw uas yuav tsum tau ib tug sib sib zog nqus hardened txheej, xws li gears nrog nruab nrab modulus, loj module gears, shafts nrog loj diameters, thiab lwm yam.
