Kufunika kwa degreasing ndi kupukuta njira zitsulo zosapanga dzimbiri ukhondo machubu

Muli mafuta m'mapaipi azitsulo osapanga dzimbiri akamaliza, ndipo amafunikira kukonzedwa ndikuwumitsidwa njira zotsatila zisanachitike.

1. Imodzi ndikuthira chothira mafuta molunjika mu dziwe, kenaka yikani madzi ndikuviika. Pambuyo pa maola 12, mukhoza kuyeretsa mwachindunji.

2. Njira ina yoyeretsera ndikuyika chitoliro chachitsulo chosapanga dzimbiri mu mafuta a dizilo, kuziyika kwa maola 6, kenaka kuziyika mu dziwe ndi woyeretsa, zilowerere kwa maola 6, ndiyeno kuyeretsa.

Njira yachiwiri ili ndi ubwino woonekeratu. Ndi zoyera kuyeretsa zitsulo zosapanga dzimbiri mapaipi aukhondo.

Ngati kuchotsa mafuta sikuli koyera kwambiri, kudzakhala ndi zotsatira zoonekeratu pa ndondomeko yopukutira ndi vacuum annealing. Ngati kuchotsa mafuta sikuli koyera, choyamba, kupukuta kudzakhala kovuta kuyeretsa ndipo kupukuta sikudzakhala kowala.

Kachiwiri, kuwala kutatha, chinthucho chimasenda mosavuta, chomwe sichingatsimikizire chinthu chapamwamba kwambiri.

Chitsulo chosapanga dzimbiri mwatsatanetsatane chitoliro kuwongoka kumafuna kuwongola

Kuwoneka kowala, dzenje losalala lamkati:

Malizitsani kukulunga chitsulo chosapanga dzimbiri chitoliro chamkati ndi chakunja pamwamba pa roughness Ra≤0.8μm

Kukula kwamphamvu kwamkati ndi kunja kwa chubu chopukutidwa kumatha kufika ku Ra≤0.4μm (monga galasi pamwamba)

Nthawi zambiri, zida zazikulu zopukutira mwaukhondo mapaipi achitsulo chosapanga dzimbiri ndi mutu wopukutira, chifukwa kuuma kwa mutu wopukutira kumatsimikizira dongosolo la kupukuta movutikira.

BA:Bright Annealing. Panthawi yojambula chitoliro chachitsulo, chidzafunikanso kudzoza mafuta, ndipo mbewuzo zidzapundukanso chifukwa cha kukonza. Pofuna kupewa mafutawa kuti asakhalebe mu chitoliro chachitsulo, kuwonjezera pa kuyeretsa chitoliro chachitsulo, mungagwiritsenso ntchito mpweya wa argon monga mpweya wa ng'anjo panthawi yotentha kwambiri kuti muthetse kusokonezeka, ndikuyeretsanso chitoliro chachitsulo mwa kuphatikiza. argon ndi mpweya ndi mpweya pamwamba pa chitoliro zitsulo kuwotcha. Kumwamba kumatulutsa kuwala, kotero njira iyi yogwiritsira ntchito argon annealing yoyera kuti itenthe ndi kuziziritsa msanga pamwamba pake imatchedwa glow annealing. Ngakhale kugwiritsa ntchito njirayi kuwunikira pamwamba kumatha kutsimikizira kuti chitoliro chachitsulo chimakhala choyera, popanda kuipitsidwa kulikonse. Komabe, kuwala kwa pamwambaku kumamveka ngati matte pamwamba poyerekezera ndi njira zina zopukutira (makina, mankhwala, electrolytic). Inde, zotsatira zake zimagwirizananso ndi zomwe zili mu argon ndi kuchuluka kwa nthawi zotentha.

EP:electrolytic polishing (Kupukuta kwa Electro), electrolytic kupukuta ndi ntchito mankhwala anode, ntchito mfundo electrochemistry moyenerera kusintha voteji, panopa, asidi zikuchokera, ndi kupukuta nthawi, osati kupanga pamwamba owala ndi yosalala, zotsatira kuyeretsa angathenso kusintha kukana dzimbiri wa pamwamba, ndiye njira yabwino kwambiri yowunikira pamwamba. Zoonadi, mtengo wake ndi luso lake zimawonjezekanso. Komabe, chifukwa electrolytic kupukuta adzaunika chikhalidwe choyambirira cha zitsulo chitoliro pamwamba, ngati pali zokopa kwambiri, mabowo, inclusions slag, precipitates, etc. pa zitsulo chitoliro pamwamba, zingachititse electrolysis kulephera. Kusiyanitsa kwa mankhwala kupukuta ndi kuti ngakhale ikuchitikanso m'malo acidic, sipadzakhala dzimbiri malire malire a tirigu pamwamba pa chitoliro zitsulo, koma makulidwe a chromium okusayidi filimu pamwamba akhoza kulamulidwa. kuti akwaniritse kukana kwa dzimbiri kwa chitoliro chachitsulo.
