Xa usiva 'i-Co 4' iphoswa ngapha nangapha kwiindibano zocweyo okanye iintlanganiso zokuthengwa kwempahla, ihlala ibangela umfanekiso othile, ngamanye amaxesha olula kakhulu: ialloyi esekwe kwi-cobalt yokunxiba kunye nobushushu obugqithisileyo. Kodwa loo leyibhile inokulahlekisa ukuba awukho nzulu kwizinto ezibonakalayo. Ayililo elinye, ibanga lehlabathi liphela elifana ne-304 engenabala; kungaphezulu kwe-shorthand yosapho, kwaye umtyholi ukwisakhiwo esineenkcukacha-umxube othile wecobalt, ichromium, itungsten, kunye nekhabhoni echaza ukuba inxalenye yakho iyasinda kwisicelo selayini yomlilo okanye iyasilela kwangaphambi kwexesha kwisitulo sevalve yoxinzelelo oluphezulu. Ndibone iiprojekthi zimile kuba umntu ebecinga ukuba zonke iCo 4 ziziphatha ngendlela efanayo. Akunjalo.
INyaniso eNgemva kwePhepha lokuCacisa
Amaxwebhu okuthenga athanda ibhokisi ecocekileyo: Izinto: Co 4. Kodwa ukunika loo nto kwi-Foundry okanye ivenkile yomatshini sisiqalo nje sencoko. Umqobo wokuqala osebenzayo kukulandeleka kunye nephepha lokusila eliqinisekisiweyo. Sithetha ngeealloyi ezihlala zisetyenziswa kwindawo ye-aerospace okanye iivalvu zenkonzo engqongqo, ngoko awunakuthatha nje igama lomthengisi ngayo. Ndikhumbula ibhetshi yamacandelo esixhobo se-downhole apho ikhemistry yayingaphakathi koluhlu olubanzi lwe-'Co 4', kodwa i-tungsten yayikumda osezantsi ngokupheleleyo. Amalungu asebenze kakuhle, kodwa ukuxhathisa ukunxitywa kwe-abrasive kuvavanyo lwangaphandle kwakumalunga ne-15% ngaphantsi koqikelelo. I-spec yahlangatyezwa, kodwa injongo yesicelo yayingekho. Lowo ngumsantsa phakathi kwamaphepha kunye nokusebenza.
Apha kulapho intsebenziswano yexesha elide kunye nabanikezeli abadityanisiweyo ngokuthe nkqo ibalulekile. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka abo ekujuleni nasekusebenzeni, ngokwesiqhelo inendlela entsonkothileyo. Abazukubona nje u-'Co 4' kumzobo; inkqubo yabo iqala ngokungqinisisa umgangatho womgangatho ochanekileyo (ngaba yiASTM F75, ukwahluka kweStellite, okanye udibaniso lobunikazi?) kwaye emva koko balungise iqokobhe labo lokungunda okanye inkqubo yotyalo-mali kuyo. Ukuziphatha kokuqina kwezi ngxubevange kuyakhohlisa-ukuncipha ngumba omkhulu. Awunakuyigalela njengentsimbi.
Icala lomatshini likhulisa ezi zinto zifihlakeleyo. I-cobalt alloys isebenza ngokukhawuleza ngokukhawuleza. Ukuba icebo lakho lendlela yesixhobo alilunganga, awuzisikeli izinto; uyawubetha nje ube lukhuni ngakumbi, umaleko womphezulu onkeke ngakumbi oya kuqhekeza i-carbide yakho elandelayo. Uxinzelelo olupholileyo kunye nomkhombandlela azixoxiswana; kufuneka ugcine ummandla osikiweyo ubanda kwaye uhlambe iitshiphusi ngoko nangoko ukunqanda ukuwelda kwakhona. Sisingqisho esahlukileyo xa sithelekiswa nentsimbi.
Ukwenziwa koTyalo-mali: Apho iGeometry kunye neAlloy zidibana khona
Kwizinto ezintsonkothileyo-cinga iiblade zeinjini yeinjini okanye iindawo ezintsonkothileyo zesitofu se-petroli-utyalo-mali ludla ngokuba yeyona ndlela isebenzayo ye-Co 4 alloys. Inkqubo yepateni ye-wax ivumela ezo ziteshi zangaphakathi kunye neendonga ezincinci ezingenakulinganiswa. Kodwa nantsi inkcukacha ehlala ingahoywa: ukwenziwa kweqokobhe leceramic. I-cobalt alloys ine-high melting point kwaye inokuphinda isebenze. Iqokobhe eliqhelekileyo elenzelwe intsimbi engatyiwayo linokubangela ukungcoliseka komphezulu okanye ukuphela kakubi. Ababoneleli abanamava ezinto ezinzulu, onokuthi ubalinganise kwiipotfoliyo zabo kwiindawo ezifana https://www.tsingtaocnc.com, iya kuba neenkqubo ezinikezelweyo zeqokobhe zealloys ezisebenzayo. Lutyalo-mali oluyinkunzi kunye nolwazi olwahlula iingcaphephe kwiingcali ngokubanzi.
Sizame ukutshintshela kwi-caster entsha, enexabiso eliphantsi lotyalo-mali kwiipleyiti zokunxiba impompo. Imizobo ibize i-Co 4. Iisampulu zijonge ngokugqibeleleyo ngokubonakalayo. Kodwa ngexesha lovavanyo lokuqala loxinzelelo oluphezulu lwe-slurry, i-micro-cracks yasasazeka ukusuka kwinto eyaba yi-ceramic inclusions kwi-shell mold edibeneyo kunye ne-alloy surface. Uhlalutyo lokusilela lwalathe kwinkqubo yokubopha iqokobhe. Kwafuneka siyilahle yonke ibhetshi kunye nomthombo kwakhona. Iindleko zokungaphumeleli zinciphise nakuphi na ukonga okokuqala. Isifundo yayikukuba ngezi zixhobo, inkqubo ye-Foundry ibaluleke kakhulu njengetikiti lengxubevange.
I-Post-casting, unyango lobushushu yenye indawo yemigodi. Ukunciphisa uxinzelelo luhlala luyimfuneko, kodwa ukunyanga isisombululo kunye nemijikelo yokuguga ye-cobalt alloys inovakalelo olumangalisayo. Ixesha elininzi kakhulu okanye amadigri ambalwa aphezulu kakhulu, kwaye unokunyusa izigaba ezibhityileyo ezibulala ukuqina. Asiyoseti kwaye ulibale umjikelo we-oveni. Udinga ulawulo oluchanekileyo lwesithando somlilo kwaye rhoqo, i-vacuum okanye umoya olawulwayo ukunqanda ukuthotywa komphezulu. Ukukhankanywa kwe-QSY yokusebenza kunye ne-alloys ezikhethekileyo kubonisa ukuba baye bahamba ngale nto; ayisosakhono osiphuhlisayo ngobusuku.
I-CNC Machining: Ubugcisa bokususa ezona zinto zinzima
Apha kulapho ulwazi lwethiyori ludibana khona nesikhalo sokusonta. Machining cast Co 4 amacandelo ukuba imilinganiselo yokugqibela apho imida inzuzo inokususwa. Ukunxitywa kwezixhobo kuyacaca. Senze umgangatho osemgangathweni kumabakala athile e-sub-micron grain carbide, ngamanye amaxesha sisiya kwi-ceramic okanye kwi-CBN (cubic boron nitride) ukuze sigqibezele ukupasa. Kodwa nangona kunjalo, ubomi besixhobo bulinganiswa ngemizuzu, hayi iiyure. Ukubaleka okuyimpumelelo kuxhomekeke ekubambeni isixhobo esingqongqo (akukho kukhutshwa kuvumelekileyo), isixhobo somatshini esomeleleyo, kunye nokutya okulungiselelwe ngokupheleleyo kunye nezantya.
Ingcebiso esebenzayo esiyifunde kabuhlungu: ungaze uphazamise ukusikwa. Ukuba uthe wanqumama okanye wenze isikwa esiphazamisekileyo ngoyilo, umema ukusilela kwesixhobo esiyingozi. Isicwangciso-qhinga kukusebenzisa iindlela zokusila zetrochoidal ukugcina ukubandakanyeka kwesixhobo rhoqo kunye nokulawula ubushushu. Iyacotha kwiprogramu kodwa ikhawuleza ngexesha lomatshini wehlabathi lokwenyani kuba awutshintshi ukufakwa kuzo zonke ezinye iindawo.
Ngaphezu koko, i CNC Machining kwezi ngxubevange zivelisa umtya, iitshiphusi ezibukhali ezibomvu-kushushu. Ulawulo lwe-chip ngumba wokhuseleko kunye nomgangatho. Kuye kwafuneka sibuyisele iinkqubo zokupholisa zoxinzelelo oluphezulu ngokukodwa ukuze le misebenzi iqhawuke kwaye ikhuphe iitshiphusi. Umgangatho wevenkile we-Co 4 run ujongeka ngokwahlukileyo-uyangxola, ushushu, kwaye kukho ukuxinana okubonakalayo de kuphume indawo yokuqala elungileyo.
Ubonelelo lweMathiriyeli kunye neLensi yesiXeko soBonelelo
Ivela phi ingxubevange ye-Co 4 ekrwada? Lo ngumbuzo we-geopolitical and logistical question kanye njengowobugcisa. I-Cobalt yimathiriyeli yeqhinga. Ikhonkco layo lokubonelela linokuguquguquka. Iqabane elithembekileyo aliyishiyi nje loo nto; bayakunceda ukuba uyikhusele. Baye baseka ubudlelwane nabavelisi be-alloy abakhulu okanye banokucebisa ngamanye amabakala amkelekileyo kusapho lwe-Co 4 olunokuba nokufumaneka okungcono ngaphandle kokubeka esichengeni owona msebenzi ungundoqo.
Ngexesha lokuphazamiseka kobonelelo kwiminyaka embalwa edlulileyo, sasineprojekthi yeeprototypes zokufakelwa kwezonyango ezichaza ialloyi yotyando lweCoCr. Ixesha elikhokelayo ukusuka kumatshini wokuqala wokusila iiveki ezingama-40. Umnikezeli onobuchule odibeneyo ucebise ukutshintshela kwisitokhwe somgangatho ofanayo ababewuqinisekisile umsebenzi we-aerospace yangaphambili, kunye nohlengahlengiso oluncinci kunyango lobushushu lwasemva kokuphosa ukuhambelana neempawu zomatshini ezifunekayo. Igcine iprojekthi. Olo hlobo lokusombulula iingxaki luvela kumava, hayi nje incwadi yokuthenga oomatshini.
Eli lixabiso lemodeli yenkonzo yokuma enye kumacandelo abalulekileyo. Xa uphosa, unyango lobushushu, kunye CNC Machining ziphantsi kophahla olunye, njengomboneleli odibeneyo, iilophu zempendulo ziqinile. Oomatshini banokuxelela iqela labasunguli ukuba ibhetshi ethile iyintsini okanye ibangela ukunxitywa kwesixhobo esingaqhelekanga, esinokubuyela emva ekuphambukeni okuncinci kwikhemikhali yokunyibilika okanye izinga lokupholisa. Loo ngxoxo yangaphakathi ayinakwenzeka xa ulima inyathelo ngalinye kubathengisi abahlukeneyo.
Iingcamango Zokuqukumbela: Yinkqubo, Hayi nje Ukuthenga
Ke, xa ujongana neCo 4, awuthengi nyani imathiriyeli. Uthenga isakhono senkqubo yokuvelisa ehlanganisiweyo. Igama elingundoqo yindawo yokungena. Iindleko zangempela kunye nempumelelo zigqitywa yiyo yonke into eyenzekayo emva kokuba i-PO isikiwe: i-melt practice, i-mold design, imijikelezo ye-thermal, kunye nesicwangciso somatshini.
Ukujonga iprofayile yenkampani efana ne-QSY's-iminyaka engama-30 ekujuleni nasekusebenzeni, ebiza ialloys esekwe kwi-cobalt ngokukodwa-endixelela ukuba kusenokwenzeka ukuba baye bakhe ulwazi lweziko malunga nale mingeni. Iwebhusayithi yabo, https://www.tsingtaocnc.com, ayisiyondawo yokuthengisa; kumthengi wobugcisa, luphawu lweendawo zabo ezikhethekileyo ezixeliweyo. Uya kuphinda uphicothe amandla abo, kodwa iyayicutha intsimi ukusuka kwiivenkile zoomatshini ngokubanzi ukuya kwabo mhlawumbi bayasiqonda isizathu sokuba icandelo lakho le-Co 4 lingaphathwa njengebhloko yentsimbi ethambileyo.
Ekugqibeleni, impumelelo ngezi ngxubevange imalunga nokuhlonipha ukuntsonkotha kwazo. Yintsebenziswano phakathi komyili oyiqondayo imeko yenkonzo, i-metallurgist echaza ibakala elichanekileyo, kunye neqabane lokuvelisa elinezivali kunye nezisombululo zokuyenza ngaphambili. Igama elithi 'Co 4' sisiqalo nje saloo ncoko.
