Kev kho cua sov thev naus laus zis muaj qhov cuam tshuam tseem ceeb ntawm qhov zoo ntawm cov saw hlau, tshwj xeeb tshaj yog cov saw hlau maus taus.Yog li ntawd, txhawm rau tsim cov saw hlau maus taus zoo, kev kho cua sov siab tshaj plaws thiab cov cuab yeej siv yog tsim nyog.
Vim qhov sib txawv ntawm cov tuam txhab tsim khoom hauv tsev thiab txawv teb chaws hauv cov ntsiab lus ntawm kev nkag siab, kev tswj hwm ntawm qhov chaw thiab cov kev xav tau ntawm cov saw hlau maus taus zoo, muaj qhov sib txawv ntawm kev tsim, kev txhim kho thiab kev tsim cov txheej txheem kev kho cua sov rau cov saw hlau.
(1) Kev kho cua sov thev naus laus zis thiab cov cuab yeej siv los ntawm cov tuam txhab tsim khoom hauv tsev.Cov khoom siv kho cua sov hauv kuv lub teb chaws txoj kev lag luam lag luam poob qab ntawm cov teb chaws tsim kev lag luam.Hauv particular, domestic mesh siv furnaces muaj ib tug series ntawm cov teeb meem xws li cov qauv, kev ntseeg tau thiab stability.
Cov saw hlau sab hauv thiab sab nrauv yog ua los ntawm 40Mn thiab 45Mn steel daim hlau, thiab cov khoom siv feem ntau muaj qhov tsis xws luag xws li decarburization thiab tawg.quenching thiab tempering txais yuav zoo tib yam mesh siv rauv tsis muaj recarburization kev kho mob, uas ua rau ntau decarburization txheej.Cov pins, lub tes tsho thiab cov chais yog carburized thiab quenched, qhov zoo hardening qhov tob ntawm quenching yog 0.3-0.6 hli, thiab qhov tawv hardness yog ≥82HRA.Txawm hais tias lub cub tawg yog siv rau cov khoom siv tau yooj yim thiab siv cov cuab yeej siv siab, kev teeb tsa ntawm cov txheej txheem kev teeb tsa thiab kev hloov pauv yuav tsum tau ua los ntawm cov kws tshaj lij, thiab hauv cov txheej txheem tsim khoom, cov txheej txheem ntawm cov txheej txheem no tsis tuaj yeem raug kho nrog lub sijhawm tam sim. kev hloov ntawm cov huab cua, thiab qhov zoo ntawm kev kho cua sov tseem nyob ntawm qhov loj ntawm cov kws tshaj lij nyob rau ntawm qhov chaw (cov neeg ua haujlwm thev naus laus zis) Cov txheej txheem thev naus laus zis yog qhov tsawg thiab qhov ua tau zoo dua qub yog qhov tsis zoo.Noj mus rau hauv tus account cov zis, specifications thiab ntau lawm cov nqi, thiab lwm yam, qhov teeb meem no yog ib qho nyuaj rau hloov ib pliag.
(2) Kev kho cua sov thev naus laus zis thiab cov cuab yeej siv los ntawm cov tuam txhab txawv teb chaws.Nruam mesh siv furnaces los yog cam khwb cia saw kub kho cov kab ntau lawm yog dav siv txawv teb chaws.Lub tshuab tswj huab cua yog qhov paub tab heev.Tsis xav tau cov kws tshaj lij los tsim cov txheej txheem, thiab cov txiaj ntsig tsis zoo tuaj yeem raug kho txhua lub sijhawm raws li qhov hloov pauv sai ntawm cov cua hauv qhov cub;rau cov concentration ntawm carburized txheej, cov txheej txheem faib ntawm hardness, huab cua thiab kub tuaj yeem tswj tau yam tsis muaj kev hloov kho.Tus nqi hloov pauv ntawm cov pa roj carbon ntau tuaj yeem tswj tau nyob rau hauv thaj tsam ntawm ≤0.05%, qhov hloov pauv ntawm hardness tus nqi tuaj yeem tswj tau nyob rau hauv thaj tsam ntawm 1HRA, thiab qhov ntsuas kub tuaj yeem tswj tau nruj me ntsis hauv ± 0.5 txog ± 1 ℃.
Ntxiv rau qhov ruaj khov zoo ntawm sab hauv thiab sab nrauv phaj phaj quenching thiab tempering, nws kuj muaj kev ua haujlwm siab.Thaum lub sij hawm carburizing thiab quenching ntawm tus pin ncej, lub tes tsho thiab cov menyuam, qhov kev hloov ntawm qhov kev faib tawm nkhaus yog txuas ntxiv xam raws li qhov tseeb tus nqi ntawm lub qhov cub kub thiab cov peev txheej carbon, thiab cov nqi ntawm cov txheej txheem tsis raug kho thiab optimized ntawm txhua lub sij hawm los xyuas kom meej cov carburized txheej Intrinsic zoo nyob rau hauv kev tswj.
Nyob rau hauv ib lo lus, muaj qhov sib txawv loj ntawm kuv lub teb chaws maus taus saw qhov chaw kho cua sov thev naus laus zis thiab cov tuam txhab txawv teb chaws, feem ntau vim tias kev tswj xyuas zoo thiab kev lees paub qhov system tsis nruj txaus, thiab nws tseem ua lag luam tom qab tsim lub teb chaws, tshwj xeeb tshaj yog qhov txawv ntawm kev kho deg. technology tom qab kev kho cua sov.Tej yam yooj yim, siv tau thiab tsis muaj kuab paug xim txheej txheem ntawm qhov sib txawv ntawm qhov kub thiab txias los yog khaws cov xim qub tuaj yeem siv los ua thawj qhov kev xaiv.
