Pamene wina atchula Aloyi 6, chinthu choyamba chomwe chimabwera m'maganizo nthawi zambiri ndi aloyi wina wa cobalt-based hardfacing alloy. Ndiko kutengerako pang'ono, ndipo komwe ndimagawana nawo. Mapepala amawonetsa kukana kwake kwa abrasion komanso mphamvu zake zabwino, zomwe ndi zoona, koma nkhani yeniyeni ili m'mipata yogwiritsira ntchito komanso kusinthanitsa kosawoneka bwino komwe mumangophunzira m'sitolo kapena m'munda. Sichipolopolo chamatsenga; ndi chida chapadera, ndipo kumvetsetsa chikhalidwe chake ndikofunikira.
Pambuyo pa Deta Yambiri: Kupanga ndi Kugulitsa Kwachilengedwe
Zolemba mwadzina - pafupifupi 1% C, 30% Cr, 4.5% W, balance Co-ndi zachikale. Chromium yapamwamba imapangitsa kuti ikhale yolimba komanso kukana kwa okosijeni, ndichifukwa chake imatchulidwira zinthu monga mipando yamavavu m'malo ovuta. Tungsten carbides ndiye gwero lalikulu la kukana kuvala. Koma apa pali nuance yoyamba: kukula kwa carbide ndi kugawa. M'magulu ena, ngati kulimbitsa sikukuwongoleredwa bwino, mutha kupeza gawo logawanika pang'ono. Izi sizimawonekera nthawi zonse pa cert, koma mumazimva mukamakonza - malo omwe amakhala olimba pang'ono, zomwe zimayambitsa macheza a zida.
Takhala tikujambula kuchokera kuzinthu zosiyanasiyana m'zaka zapitazi, ndipo zomwe zakhala zikuyenda bwino kwambiri pamakina otsatirawa zinali zochokera kwa othandizana nawo omwe amatsindika za kuwongolera kwa kusungunula ndi kuthira. Ndi chikumbutso kuti nambala ya aloyi ndi njira yoyambira; Luso la ophika ndilofunika kwambiri. Apa ndipamene bwenzi lakale limakonda Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. kusonyeza mtengo wake. Ndi zaka zawo za 30+ mu chipolopolo ndi kupanga ndalama, amapeza kusasinthasintha sikungokhudza kugunda manambala a chemistry, ndi za mbiri yonse yotentha ya gawolo.
Kugulitsana, nthawi zonse, kumakhala pakati pa kuuma / kukana abrasion ndi kutengeka kwa ming'alu. Aloyi 6 nthawi zambiri amaonedwa kuti ali ndi mphamvu yolimbana ndi kuuma kwake, koma zabwino ndizofanana. Ngati mupanga gawo lokhala ndi ngodya zakuthwa zamkati ndikutchulapo gawo lalikulu la Alloy 6, mukufunsa vuto. Tinaphunzira izi kumayambiriro ndi mbale yopangira pompa. Mapangidwewo anali ndi ngodya ya madigiri 90 mu gawo lapansi. Chophimba cha Alloy 6, pamene chinkazizira ndi kufota, chinang'ambika kupyola muzitsulo zopanikizikazo. Yankho silinali aloyi yosiyana, koma kusintha kwapangidwe kukhala ngodya yozungulira. Nkhaniyo inatiuza zimene zinkafunika.
Zowona Zantchito: Casting vs. Overlay
Zolemba zambiri za Aloyi 6 Zili ndi mawonekedwe a weld overlay kapena kupopera kwa matenthedwe. Koma kugwiritsidwa ntchito kwake ngati chigawo choponyedwa ndikofunikira, ngati kocheperako, domain. Awa ndi gawo lofunikira la maziko ngati QSY. Kuponyera Aloyi 6 m'mawonekedwe ovuta - ganizirani zisindikizo za turbine kapena zida za eni - kumabweretsa zovuta zosiyanasiyana. Fluidity ndi yotsika kuposa ma aloyi opangidwa ndi faifi tambala, motero njira yolowera ndi yokwera iyenera kupangidwa kuti ipewe kusokoneza, makamaka m'zigawo zoonda.
Tinali ndi pulojekiti yopangira gawo lowongolera ma valve omwe amafunikira njira zamkati zamkati. Chitsanzo choyambirira, chopangidwira chitsulo chokhazikika, chinalephera kwambiri ndi Aloyi 6. Chitsulocho sichikanadzaza bwino kwambiri chisanayambe kuzizira. Kukonzekera, komwe kunapangidwa mogwirizana ndi gulu lawo la uinjiniya, kunakhudzanso kusintha magawo opangira ndalama - makamaka kutentha kwa nkhungu kusanachitike komanso kutentha kothira kosinthidwa pang'ono. Sikunali kusintha kwakukulu, koma kunali kusintha kolondola kobadwa ndi zochitika. Mutha kupeza njira yawo yopangira ma aloyi apadera mwatsatanetsatane patsamba lawo https://www.tsingtaocnc.com, yomwe imasonyeza ntchito yawo ndi cobalt ndi nickel-based alloys.
Pambuyo poponya, kufunikira kwa chithandizo cha kutentha ndi mfundo ina yosankha. Kuti musavutike kwambiri ndi abrasion, nthawi zambiri mumayisiya ngati ikutayidwa. Koma ngati mukufuna kuthetsa kupsinjika kuti mukhazikike pakupanga makina omaliza, kuzungulira kwapang'onopang'ono ndikofunikira. Chinyengo ndikusunga kutentha ndi nthawi pazenera zomwe sizimayambitsa kukula kwambewu kapena carbide coalescence, zomwe zingafewetse zinthuzo. Ndikuchita bwino.
Kugaya Machining: Kwenikweni
Apa ndi pamene chiphunzitso chimakumana ndi gudumu lopera. Makina opanga Aloyi 6 sikuli kwa anthu ofooka mtima kapena opanda zida. Zimagwira ntchito-zimalimba mwamakani. Ngati chida chanu sichili chakuthwa, ngati liwiro lanu ndi ma feed anu ndi amantha, mudzayang'ana pamwamba ndikusandutsa chiphaso chotsatira kukhala chowopsa. Timakhazikika pamakhazikitsidwe olimba a CNC, zoyika za ceramic kapena CBN zotembenuza, ndi mawilo a diamondi pogaya. Ngakhale zili choncho, moyo wa zida ndi kachigawo kakang'ono ka zomwe mungapeze ndi chitsulo.
Malangizo othandiza: pobowola, kubowola ndikofunikira kuti muthyole chip ndikuchichotsa. Kusiya chitoliro kuti chikhudze chitolirocho kumapangitsa kutentha kokwanira kuti chigwire ntchito - kuumitsa pansi pa dzenje, zomwe zingathe kuyimitsa kubowola kapena kuswa. Tinawononga zigawo zingapo zamtengo wapatali izi zisanakhale gawo losakambirana la ndondomekoyi. Zikumveka ngati zofunikira, koma pansi pa kukakamizidwa kwa kupanga, zoyambira ndizofunikira kwambiri kuti zifulumire.
Mapeto ndi ofunikanso. Pansi pa nkhope ya chisindikizo cha Alloy 6 idzachita mosiyana kwambiri ndi yotembenuzidwa ponena za kuvala ndi kutayikira. Mafotokozedwewo ayenera kutchula osati aloyi, koma mapeto omaliza ndi momwe angakwaniritsire. Mzerewu watsatanetsatane umalekanitsa chojambula chomwe chimagwira ntchito kuchokera ku chimodzi chomwe chimayambitsa mutu pakupanga ndi kulephera muutumiki.
Kusanthula Kulephera: Pamene Aloyi 6 Si Yankho
Ndimakumbukira nkhani ina yokhudza choyimbira pampu yamatope. Wogulayo anaumirira Aloyi 6 kutengera kupambana kwam'mbuyomu mu ntchito ina. Kulephera kunali kofulumira komanso koopsa - osati kutha, koma kusweka kophwanyika. Nkhani yake? The slurry mu ntchito yatsopanoyi anali lalikulu, lakuthwa m'mphepete silika particles ndi kwambiri cavitation. Aloyi 6 anakana abrasion bwino, koma ophatikizana zotsatira za mkulu-liwiro zimakhudza kuchokera particles ndi cavitation thovu analenga yaying'ono ming'alu kuti zimafalitsidwa mofulumira kudzera ndi Chimaona masanjidwewo.
Ichi chinali cholakwika posankha zinthu. Chinthu cholimba, chochulukira ngati chitsulo choyera cha chrome chikhoza kukhala chopunduka m'malo mosweka, kapena alloy yopangidwa ndi faifi yokhala ndi mawonekedwe onyowa bwino akanafufuzidwa. Zinatiphunzitsa kuti kukana abrasion si chinthu chimodzi. Muyenera kuthyola makina ovala: kodi ndi kutsetsereka kotsetsereka, kukanda pang'onopang'ono, kugaya kwambiri, kapena kukwapula kophatikizana? Alloy 6 imapambana mu ziwiri zoyambirira, koma magwiridwe ake amatsika pazovuta kwambiri.
Apa ndipamene kukhala ndi bwenzi lapamtima lomwe limamvetsetsa nkhani ndikofunika. Kukambitsirana kwaukadaulo wabwino ndi mainjiniya ogwiritsira ntchito pakampani ngati QSY sikutanthauza kuti mungapange izi? Ndi za chiyani gawo ili likuyenera kupirira? Zomwe amakumana nazo pamitundu yosiyanasiyana zimawalola kufunsa mafunso olondola ndipo nthawi zina amawonetsa njira zina zomwe zingakhale zoyenerera bwino, ngakhale zitatanthawuza zinthu zosiyana ndi mbiri yawo.
Sourcing ndi Supply Chain Reality
Zomwe zili mu cobalt zimapanga Aloyi 6 kutengera kusinthasintha kwamitengo ndi geopolitics zaupangiri. Ndizowona zomwe zakakamiza mainjiniya ambiri kuti awunikenso zomwe zanenedwa. Kodi ntchito ingatheke ndi chitsulo chosinthidwa kapena aloyi wina wopanda cobalt? Nthawi zina inde, nthawi zina ayi. Pazinthu zovuta zomwe kuphatikiza kwake kwapadera kwa kuuma kotentha ndi kukana kwa dzimbiri sikungalowe m'malo, muyenera kungoyang'anira ngoziyo.
Izi zimapangitsa kuti ubale wanthawi yayitali ndi ogulitsa odalirika ukhale wofunikira. Mufunika malo osungira omwe ali ndi mayendedwe okhazikika komanso kuya kwake kwaukadaulo kuti muthe kusintha ma alloying achiwiri mkati mwazofunikira kuti muchepetse mtengo popanda kusokoneza magwiridwe antchito - ngakhale uku ndi kuvina kosakhwima. Mbiri yogwira ntchito yazaka 30 yamakampani ngati Mtengo wa QSY akuwonetsa kuti adayendapo m'misika iyi m'mbuyomu ndipo ali ndi mphamvu zogulira zinthu kuti akhale gwero lokhazikika, lomwe ndi lofunikira monga luso lawo laukadaulo.
Pomaliza, nthawi zonse, yesetsani kuyesa nkhani yoyamba. Ngakhale ndi ogulitsa odalirika, yendetsani magawowo kudzera mumayendedwe awo - macheke akuuma, ma micrography kuti muwone mawonekedwe a carbide, ndipo ngati kuli kotheka, kuyesa koyeserera. Ndilo gawo lomaliza, lofunikira kuti mutsimikizire Aloyi 6 mumalandira machitidwe ngati Aloyi 6 omwe mudapanga nawo. Imatsekereza kusiyana pakati pa lonjezo lachindunji ndi zenizeni za gawo lomwe lili m'manja mwanu.
