Dab tsi yog qhov zoo ntawm quenching cov khoom siv ntau zaus nws tus kheej

Daim ntawv thov ntawm high-frequency quenching tau nyob rau hauv cov hlau kev lag luam rau lub sij hawm ntev, maj mam hloov cov tsoos kho cua sov cov cuab yeej, thiab nruam technologies nyob rau hauv cov txheej txheem hlau los txhim kho kev ua hauj lwm efficiency ntawm lub workpiece. Ob hom khoom siv nruab nrab zaus quenching, uas zoo ib yam li high-frequency quenching, muaj cov cuab yeej zoo sib xws, tab sis cov khoom sib txawv quenching yog xaiv raws li cov txheej txheem sib txawv. Niaj hnub no, cia peb saib qhov zoo ntawm quenching zoo ntawm high-frequency quenching khoom.

High-frequency quenching mas siv lub hauv paus ntsiab lus ntawm electromagnetic induction, thiab induced tam sim no generated yuav ua tau ib tug series ntawm cua sov, kev kho cua sov thiab lwm yam txheej txheem ntawm lub workpiece. Tom qab ntawd nws muaj cov yam ntxwv thiab qhov zoo uas cov cuab yeej zoo tib yam tsis muaj. Lub ntsiab zoo tshaj plaws yog:

1. Qhov saum npoo ntawm lub workpiece tsis yooj yim rau oxidized. Vim yog cua sov, lub workpiece yog yooj yim nyob rau hauv kev sib cuag nrog oxygen, thiab saum npoo yog oxidized, uas yuav cuam tshuam cov cua kub ntawm lub workpiece. Hloov chaw, cov txheej txheem quenching siab tsis tsuas yog tsis ua rau oxidation ntau dhau, tab sis cov cua kub ceev ntawm lub workpiece kuj ceev, uas txhim kho kev ua hauj lwm efficiency, thiab lub workpiece nws tus kheej yog tsis tshua muaj deformed.

2. Cov txheej txheem ntawm cov txheej txheem txheej txheej ntawm cov khoom siv high-frequency quenching workpiece yog nyob rau hauv 1-1.5mm, uas tsis zoo li qhov nruab nrab zaus quenching. Qhov tob ntawm txheej hardened ntawm qhov nruab nrab zaus quenching tuaj yeem ncav cuag li ntawm 1-5 hli, yog li qhov nruab nrab zaus quenching yog siv thaum high-frequency quenching tsis tuaj yeem ua raws li cov txheej txheem. Tau kawg, yog tias nws yog ib qho chaw ua haujlwm nrog cov txheej txheem sib sib zog nqus, peb siv cov txheej txheem hluav taws xob ntau zaus quenching.

3. Cov txheej txheem cua sov ntawm cov cuab yeej yog cov cua sov uas tsis sib cuag, uas tuaj yeem ua kom sov lub tshuab ua haujlwm thib ob deformed.

4. Cov txheej txheem quenching ntawm lub workpiece tuaj yeem tswj tau, thiab nws tuaj yeem nruab nrog lub tshuab quenching kom ua tiav quenching tas li, segmented quenching thiab tom qab scanning. Txoj kev no yog qhov tsim nyog rau qee qhov workpieces nrog cov kev cai nruj.

5. Cov txheej txheem kev kho cua sov ua haujlwm ntawm cov khoom siv hluav taws xob ntau zaus quenching yog yooj yim heev thiab tsis tshua muaj nqi.
