Yuav ua li cas los xyuas kom meej qhov tsim nyog tej yam kev mob rau qhov zoo ntawm induction cua sov quenching khoom

1. Cov khoom tsim nyog zam txim rau kev tsim qauv thiab kev kho cua sov ua ntej

Cov qauv tsim ntawm cov qauv yuav tsum haum rau cov yam ntxwv ntawm induction cua sov, thiab nws cov qauv zoo yuav tsum yooj yim dua kom tau txais cov cua sov sib xws. Yuav tsum ua kom tau raws li cov kev cai ntawm kev kho cua sov induction, cov khoom yuav tsum tau pre-rhuab, thiab cov khoom uas yuav tsum tau txhim kho hnav tsis kam yog feem ntau normalized; cov khoom los yog nyias-walled qhov chaw uas yuav tsum tau muaj zog thiab siab hnav tsis kam yog feem ntau quenched thiab tempered. .

2. Kev xaiv kom raug ntawm cov khoom thiab cov khoom siv, tsim nyog cov txheej txheem ua haujlwm

Nws yog feem ntau tsim nyog siv intrinsically nplua-grained hlau ua cov khoom siv rau induction cua sov kho qhov chaw. Qhov tshwj xeeb tseem xav tau kev xaiv cov ntsiab lus carbon ntawm cov hlau. Cov hlau feem ntau siv yog: 35, 40, 45, 50, ZG310-570, 40Cr, 45Cr35rMo, 42CrMo, 40MnB thiab 45MnB, thiab lwm yam.

Feem ntau siv cam khwb cia hlau muaj xws li: hlau cam khwb cia hlau, malleable cam khwb cia hlau, grey cam khwb cia hlau thiab alloy cam khwb cia hlau.

Cov ntsiab lus pearlite (ntim feem) ntawm nodular cam khwb cia hlau rau induction cua sov yog pom zoo kom 75% lossis ntau dua. Nws yog qhov tsim nyog rau cov ntsiab lus pearlite (ntim feem) kom ntau dua 85%, thiab cov duab ntawm pearlite zoo dua flake; malleable cam khwb cia hlau yuav tsum tau graphite sib piv Chop finely thiab faib tusyees.

3. Yuav tsum tau ua ntej quenching

(1) Cov khoom siv ntawm cov khoom ua tau raws li cov kev cai tsim.

(2) Qhov saum npoo ntawm cov khoom yog huv si thiab tsis muaj roj thiab hlau filings.

(3) Tsis muaj qhov tsis xws luag xws li pob, tawg, corrosion, thiab oxide nplai ntawm qhov chaw.

(4) Lub roughness siab ntawm qhov quenched ntawm qhov chaw ntawm qhov chaw yuav tsum sib npaug los yog zoo dua Ra6.3μm, yuav tsum tsis muaj decarburization txheej, burrs, crushing, thiab lwm yam.

(5) Cov khoom tau dhau los ua qhov qub thiab quenching thiab tempering ua ntej raws li cov txheej txheem kev cai, thiab hardness ua tau raws li qhov yuav tsum tau ua. Lub grain loj ntawm cov qauv metallographic yuav tsum yog 5-8.

(6) Lub geometric qhov ntev ntawm cov khoom ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem, thiab tsis muaj cov txheej txheem ploj lossis cov txheej txheem dhau.
