Mumamva 'zigawo za cobalt based alloy' ndipo nthawi yomweyo mumaganiza 'zapamwamba,' 'mlengalenga,' 'implants zachipatala.' Izi sizolakwika, koma ndi chithunzi chosakwanira. Zowona m'malo ogulitsa makina ndizovuta kwambiri, zodzaza ndi kunyengerera ndi zizolowezi zosayembekezereka zomwe mapepala samakonzekeretsa nthawi zonse. Pali lingaliro lolakwika lodziwika kuti chifukwa ndi 'superalloy,' imakhululukira kusawongolera njira. Muzondichitikira zanga, ndi zosiyana; zimafuna kukhwimitsa kwambiri, osati zochepa, ndipo zimalanga zongoganizira mwankhanza.
Aloyi Si Aloyi Yokha
Tikamatchula ntchito, titi, gawo losindikizira la turbine cobalt zochokera aloyi, nkhondo yoyamba nthawi zambiri imakhala kufunafuna chuma. Sikuti magiredi onse a Co-Cr-W kapena Co-Cr-Mo amapangidwa mofanana, ngakhale pansi pa AMS kapena ASTM yofanana. Tsatirani zinthu zochokera kumadzi osungunuka osiyanasiyana, kapangidwe kake ka katundu wa bar kapena zinthu zobwezeretsanso - izi zimasintha mochenjera machinability ndipo, makamaka, kuyankha kupsinjika panthawi yopanga ndalama. Tinaphunzira izi movutirapo zaka zapitazo pakugwiritsa ntchito ma nozzles oyaka moto. Chemistry inali 'mwachidziwitso,' koma zigawozo zidapanga ming'alu yaying'ono pakuchotsa zipolopolo pambuyo poponyedwa. Wolakwa? Zomwe zili ndi silicon yotsika pang'ono kuchokera kwa wogulitsa watsopano zomwe zidakhudza kukana misozi yotentha. Chomwecho chinali chipata chachikulu, ndipo tidalowa momwemo.
Apa ndipamene maubwenzi anthawi yayitali ndi ogulitsa zinthu zodziwika bwino amakhala osayanjanitsika. Ndizochepa za satifiketi komanso zambiri zokhudzana ndi batch-to-batch. Kwa kampani ngati Qingdao Qiangsenyuan Technology (QSY), yomwe ili ndi zaka makumi atatu pakupanga ndi kupanga makina, kutsimikizira kuti kudalirana kwa chain kwakhala gawo lalikulu la ntchito. Simungathe kupanga zodalirika pazakudya zosagwirizana. Ntchito yawo yonse magawo a aloyi a cobalt, ma aloyi a faifi tambala, ndi zitsulo zapaderazi zimatanthawuza kuti awonapo zinthu izi zimasewera mobwerezabwereza, kupangitsa malingaliro awo ogula.
Chigawo china ndi 'mawonekedwe' a alloy. Kodi tikuyamba ndi virgin bar for Machining? Mukugwiritsa ntchito kubwereranso mu ng'anjo yathu yopangira ndalama? Kapena kugwiritsa ntchito zida zomwe zimatumizidwa kwa ife kuti timalizitse? Njira iliyonse ili ndi zovuta zosiyanasiyana. Kujambula cobalt aloyi chigawocho chidzakhala ndi chikhalidwe chosiyana chamkati chamkati komanso chotheka chophatikizira poyerekeza ndi billet yopangidwa. Pulogalamu yanu ya CNC ndi njira yazida ziyenera kuwerengera kusiyana komweku kuyambira pakudulidwa koyamba.
Kuponya Ndalama: Kumene Matsenga ndi Mutu Zimachitika
Nkhono za zipolopolo ndi kuyika ndalama ndizopitako zovuta, pafupi ndi neti-mawonekedwe magawo a aloyi a cobalt. Kukhazikika kwapang'onopang'ono ndi kumaliza kwapamwamba ndizabwino kwambiri, koma zenera lantchito ndi lopapatiza. Ma aloyi a Cobalt amakhala ndi malo osungunuka kwambiri ndipo nthawi zambiri amatenthetsa bwino. Izi zimabweretsa kutsika kwamphamvu kwamafuta panthawi yolimba. Ngati njira yanu yolowera ndi yokwera sinapangidwe mwangwiro - ndipo ndikutanthauza bwino gawo la geometry - mudzapeza shrinkage porosity kapena malo otentha omwe amakhala malo oyambitsa ming'alu.
Nthawi ina tinakhala masabata kuyesa kuthetsa porosity mu flange wandiweyani wa chigawo cha valve. Dongosolo la data linanena kuti kutayika kwabwino. Kulowera kwathu koyamba kumatsatira malamulo okhazikika achitsulo. Izo zinalephera. Tinayenera kupita ku njira yaukali, yotentha kwambiri kuti tisunge madzi achitsulo m'chigawocho, chomwe chikanatha kukokoloka kwa nkhungu. Unali mchitidwe wolinganiza womwe unathetsedwa kudzera mu mayesero obwerezabwereza, osati chiphunzitso cha mabuku. Iyi ndiye R&D yoyipa yomwe imachitika pansi pashopu.
Pambuyo poponya, kuchotsa chipolopolo ndikofunikira. Ma alloys awa amagwira ntchito molimba kwambiri. Ngati ndinu okwiya kwambiri ndi makina ogogoda, mutha kuyambitsa kupsinjika komwe kumalumikizana ndi makina opanikizika, zomwe zimapangitsa kuti asokonezeke. Nthawi zambiri timagwiritsa ntchito kuphatikiza kwa vibration ndi kugwedezeka kosamala kwa kutentha. Ngakhale pamenepo, simudzatsimikiza mpaka gawo loyamba lipitirire pa CMM. Gawoli limafunikira kuleza mtima komwe kumatsutsana ndi zovuta za nthawi yopanga.
Machining: Luso Lachiwawa Cholamuliridwa
Machining magawo a aloyi a cobalt ndi pamene moyo zida zongopeka zimakumana ndi zenizeni. Zidazi zimakhalabe ndi mphamvu pakatentha kwambiri, zomwe zikutanthauza kuti 'sizifewa' pofika kumapeto. M'malo mwake, amachoka ndikugwira ntchito-kuumitsa malo omwe mukuyesera kudula. Chofunikira ndikusunga nthawi zonse, kuyanjana kwabwino ndi zida zakuthwa, zapadera - ma carbide opangidwira ma aloyi otentha kwambiri, okhala ndi zokutira zapadera monga AlTiN.
Kulakwitsa kwakukulu ndikuchepetsa mitengo ya chakudya kuti ikhale 'otetezeka.' Izi nthawi zambiri zimapangitsa kuti zinthu ziipireipire, zomwe zimapangitsa kuti chidacho chizipaka m'malo mometa ubweya, kutulutsa kutentha kwambiri ndikufulumizitsa kuuma kwa ntchito. Muyenera kukhala mwamakani mkati mwa magawo olondola. Coolant ndi mkangano wina. Zoziziritsa zoziziritsa kukhosi zothamanga kwambiri, kudzera pazida zimangofunika kutulutsa tchipisi ndikuwongolera kutentha, koma zoperekera ziyenera kukhala zopanda cholakwika. Kusokoneza kulikonse kumabweretsa kulephera kwa chida nthawi yomweyo. Ndawonapo mphero yomaliza ya $ 200 ikuwonongeka mumasekondi chifukwa mzere woziziritsa uli ndi kink yaying'ono.
Kukonzekera ndi theka la nkhondo. Chifukwa cha mphamvu zodula kwambiri komanso kupsinjika kotsalira kuchokera pakuponyedwa, magawo amatha kusuntha. Mufunika zida zolimba, zomwe nthawi zambiri zimakhazikika, zomwe zimathandizira gawolo popanda kukakamiza kupsinjika komwe kumabwera pambuyo pake. Kwa mawonekedwe ovuta a tsamba la turbine, titha kuthera nthawi yochuluka kupanga ndi kutsimikizira mawonekedwewo monga momwe makina amapangira okha. Si zachilendo kukhala ndi nkhani yoyamba yomwe gawolo liri langwiro koma osakhazikika pamndandanda chifukwa mumapeputsa mphamvu yoletsa yomwe ikufunika kuti mupewe macheza.
Real-World Application ndi Mitundu Yolephera
Zambiri mwa zigawozi sizingokhala pa alumali; iwo ali m'malo olanga. Ganizirani za ma valve otulutsa mpweya m'mainjini ochita bwino kwambiri kapena kuvala mapepala mu zida zopangira mankhwala. Njira yolephereka yomwe nthawi zambiri timayesetsa kuipewa si kuthyoka kowopsa, koma kuwonongeka kwapang'onopang'ono monga kutentha kwambiri kwa okosijeni, sulfidation, kapena kuvala kovutitsa.
Ndikukumbukira nkhani ina ya kasitomala yemwe amafunikira zilolezo zosamva kuvala pamzere wotentha. Poyamba adagwiritsa ntchito chida cholimba chachitsulo, chomwe chinalephera mofulumira. Tinapanga a cobalt zochokera aloyi monga Stellite 6 chifukwa cha kuuma kwake kotentha komanso kukana kwa galling. Ziwalozo zidachita bwino, koma patatha miyezi isanu ndi umodzi, zidawoneka mosayembekezereka. Chifukwa chake? Opaleshoniyo inachititsa kuti pakhale kutentha kwambiri, komwe sitinadziwe bwinobwino. Thermal shock inachititsa kutsindika kuti, kuphatikizidwa ndi alloy's low ductility pa kutentha kotsika, kumayambitsa kutopa kwa ming'alu. Yankho silinali kusintha kwakuthupi, koma kapangidwe kake kuti muwonjezere mpumulo kuti muchepetse kupsinjika. Linali phunziro poyang'ana kupyola katundu deta datasheet kuti zonse dongosolo mogwirizana.
Apa ndipamene zokumana nazo za opanga zinthu pa ma aloyi osiyanasiyana zimapindula. Sitolo yomwe yagwira ntchito kwambiri ndi zitsulo zosapanga dzimbiri chifukwa cha dzimbiri ndi cobalt zochokera aloyi chifukwa kuvala kumapanga chidziwitso cha kulephera kwa malonda awa. Atha kufunsa mafunso oyenera okhudza malo ogwirira ntchito omwe wopanga sangaganize kuti afotokoze.
Bizinesi Yowapanga: Kusagwirizana Pa Hype
Pamapeto pake, kupanga odalirika magawo a aloyi a cobalt sizokhudza kukhala ndi makina owoneka bwino kwambiri a 5-axis (ngakhale izi zimathandiza). Ndizokhudza kayendetsedwe ka kayendetsedwe kake ndi chidziwitso cha mabungwe. Ndizolemba zomwe zidagwira ntchito komanso, koposa zonse, zomwe sizinagwire ntchito yomaliza yofananayo. Ndizokhudza kukhala ndi metallurgists omwe amatha kuwerenga malo ophwanyika ndi makina opangira makina omwe amatha kumvetsera phokoso la kudula ndikudziwa kuti zikuyenda molakwika.
Makampani omwe amakhala mu niche iyi, monga QSY (Qingdao Qiangsenyuan Technology), amakhala ndi kuya kwake. Mbiri yawo yazaka 30 pakupanga nkhungu ndi kupanga ndalama, kuphatikiza makina amkati a CNC, akuwonetsa kuti adayika maphunzirowa mkati. Sakungogulitsa gawo; akugulitsa luso loyendetsa ulendo wonse kuchokera ku chitsulo chosungunula kupita ku chinthu chomalizidwa, cholondola chomwe chitha kugwiritsidwa ntchito movutikira. Kwa wogula, kuwongolera komaliza mpaka kumapeto nthawi zambiri kumakhala kwamtengo wapatali kuposa kupulumutsa mtengo wocheperako, chifukwa kumachepetsa chiopsezo cha kulephera kowopsa, kokwera mtengo.
Msika wa zigawozi ukukula, makamaka mu mphamvu ndi makina apadera mafakitale. Koma chotchinga cholowera ndi chachikulu. Si bizinesi yogulitsa. Kupambana kumatengera kulemekeza umunthu wazinthu, kuyika ndalama mwa anthu oyenera ndi njira, ndikumvetsetsa kuti nthawi zina, njira yabwino kwambiri imaphatikizira kulankhulana ndi kasitomala. cobalt aloyi ndi muzitsulo zosapanga dzimbiri zosapanga dzimbiri zomwe zidzachita mokwanira pamtengo wamtengo wapatali ndi mutu. Kudziwa nthawi yoti musagwiritse ntchito ndikofunikira monga kudziwa kupanga.
