Kupaka Carburizing & Nitriding

Kodi Carburizing & Nitriding ndi Chiyani?

Vacuum Carburizing yokhala ndi Acetylene (AvaC)

Njira yopangira ma carburizing ya AvaC vacuum ndi ukadaulo womwe umagwiritsa ntchito acetylene kuti athetse vuto la kupanga soot ndi phula lomwe limadziwika kuti limachokera ku propane, pomwe limawonjezera mphamvu ya carburizing ngakhale pakhungu kapena m'mabowo.

Chimodzi mwa zabwino kwambiri za njira ya AvaC ndi kupezeka kwa kaboni wambiri, zomwe zimapangitsa kuti carburizing ikhale yofanana kwambiri ngakhale pa geometries zovuta komanso kuchuluka kwa katundu wambiri. Njira ya AvaC imaphatikizapo jakisoni wina wa acetylene (boost) ndi mpweya wosalowerera, monga nayitrogeni, kuti ifalikire. Pa jakisoni wowonjezera, acetylene imalekanitsidwa kokha ikakhudzana ndi malo achitsulo chonse zomwe zimapangitsa kuti carburizing ikhale yofanana.

Phindu lodabwitsa kwambiri la AvaC limapezeka pamene mpweya wosiyanasiyana wa hydrocarbon wopangira carburizing wochepa mphamvu uyesedwa mphamvu yake yolowera m'mabowo ang'onoang'ono, aatali, komanso osawoneka bwino. Kupaka vacuum carburizing ndi acetylene kumabweretsa mphamvu yonse ya carburizing kutalika konse kwa bore chifukwa acetylene ili ndi mphamvu yosiyana kwambiri ya carburizing kuposa ya propane kapena ethylene.

Ubwino wa njira ya AvaC:

Mphamvu yopitilira yopitilira muyeso

Kubwerezabwereza kwa njira yotsimikizika

Kutumiza mpweya wabwino kwambiri wa acetylene

Dongosolo lotseguka komanso losavuta kukonza

Kuchuluka kwa mpweya woipa

Kuchepetsa nthawi yogwirira ntchito

Kapangidwe kabwino ka zinthu zazing'ono, kukana kupsinjika maganizo, komanso khalidwe labwino kwambiri la zinthu pamwamba pake

Kukulitsa ndalama kuti pakhale mphamvu zowonjezera

Kutha kuzimitsa zinthu zosiyanasiyana pogwiritsa ntchito helium, nayitrogeni, mpweya wosakaniza, kapena mafuta

Ubwino kuposa uvuni wa mlengalenga:

Malo abwino ogwirira ntchito okhala ndi kapangidwe ka khoma lozizira, komwe kumachepetsa kutentha kwa chipolopolo

Palibe zophimba zotsika mtengo kapena milu ya utsi zomwe zimafunika

Mabizinesi oyambira mwachangu komanso otseka

Sipafunikira majenereta a gasi a endothermic

Zitofu zozimitsira mpweya zimafuna malo ochepa pansi ndipo sizimatsuka pambuyo pochotsa mafuta ozimitsira mpweya

Palibe zofunikira zapadera kapena maziko ofunikira

Kuyendetsa mpweya wa kaboni

Kukonza kaboni ndi njira yolimbitsira zinthu mofanana ndi kukonza kaboni, ndi kuwonjezera nayitrogeni, yomwe imagwiritsidwa ntchito kuwonjezera kukana kuwonongeka ndi kuuma pamwamba. Poyerekeza ndi kukonza kaboni, kufalikira kwa kaboni ndi nayitrogeni kumawonjezera kulimba kwa kaboni wamba ndi zitsulo zochepa.

Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:magiya ndi ma shaftma pisitonima rollers ndi ma bearingma levers mu machitidwe oyendetsedwa ndi hydraulic, pneumatic ndi mechanical.

Njira yochepetsera mpweya wa carbonitriding (AvaC-N) imagwiritsa ntchito acetylene ndi ammonia. Monga momwe zimakhalira ndi carburizing, gawo lomwe limatuluka lili ndi bokosi lolimba komanso losawonongeka. Komabe, mosiyana ndi carburizing ya AvaC, kuya kwa nayitrogeni ndi carbon case komwe kumachitika kuli pakati pa 0.003″ ndi 0.030″. Popeza nayitrogeni imawonjezera kulimba kwa chitsulo, njirayi imapanga zigawo zomwe zimakhala ndi kulimba kwakukulu mkati mwa kuya kwa bokosi lomwe lasonyezedwa. Popeza carbitriding imachitika pa kutentha kochepa pang'ono kuposa carburizing, imachepetsanso kusokonekera chifukwa cha kuzimitsidwa.

Kutulutsa Nitriding & Nitrocarburizing

Kuyika nitriding ndi njira yolimbitsira chitsulo yomwe imafalitsa nayitrogeni pamwamba pa chitsulo, chomwe nthawi zambiri chimakhala ndi kaboni yochepa, komanso chopanda aloyi. Chimagwiritsidwanso ntchito pa zitsulo zapakati ndi zapamwamba, titaniyamu, aluminiyamu ndi molybdenum.

Nitrocarburizing ndi njira yosaya kwambiri yopangira nitriding pomwe nayitrogeni ndi kaboni zonse zimafalikira pamwamba pa gawolo. Ubwino wa njirayi ndi kuthekera kolimbitsa zinthu pa kutentha kochepa komwe kumachepetsa kupotoka. Nthawi zambiri imakhala yotsika mtengo poyerekeza ndi carburizing ndi njira zina zolimbitsira zikwama.

Ubwino wa Nitriding ndi Nitrocarburizing ndi monga kulimba bwino komanso kukana dzimbiri.

Kuyika nitriding ndi nitrocarburizing zimagwiritsidwa ntchito pa magiya, zomangira, masipiringi, ma crankshaft ndi ma camshaft, pakati pa zina.

Mafuko ophikira amalangizidwa kuti azigwiritsidwa ntchito poika mafuta m'zitini ndi kuyika nitriding.
