Xa umntu esithi 'inxalenye ye-incoloy', abaninzi bacinga ukuba bathetha nje nge-alloy ye-nickel ephezulu ekwazi ukumelana nobushushu. Nantso umphezulu. Inyaniso kukuba, kukuzibophelela. Awuyiodoli nje inxalenye; ubhalisela inkqubo yonke yetsheyini apho ulwazi lwezinto eziphathekayo yinxalenye elula. Olona celomngeni lusekukwenziweni—ukwenza izinto—ukubunjwa, ukwenza oomatshini, umdaniso wonyango olushushu. Ndibone uyilo oluninzi lusilela ngenxa yokuba baphatha i-Incoloy 825 okanye i-925 njengentsimbi enkulu engenasici. Ayiyo. Lirhamncwa elifuna intlonipho kwipateni yokuqala.
Inyani yoMgangatho weFoundry
Masiqale apho iqala khona: ukugalela. Ngezi ngxubevange, ngakumbi ezona chromium ziphezulu zinjalo I-Icoloy I-800H, inkqubo yokubumba iqokobhe incinci malunga nobugcisa kwaye ngakumbi malunga nolawulo olukhohlakeleyo. Uyilo lokungena ayisiyohambo nje; yeyokuqinisa umkhombandlela ukunciphisa ukukrazuka okushushu. Oku sikufunde kabuhlungu kwibhetshi yemizimba yevalvu kwiminyaka eyadlulayo. Amalungu abonakala egqibelele, kodwa uvavanyo loxinzelelo luveze iintanda ezincinci ecaleni kwecandelo elibonakala lingenamkhethe. Umoni? Ukupholisa izinga lokungahambelani kwinqanaba elishinyeneyo. Umahluko wobushushu bomngundo wawuyi-30 ° C ukusuka kwelinye icala le-autoclave ukuya kwelinye. Kuphelele apho.
Apha kulapho umnombo we-Foundry's ubonisa khona. Ivenkile ethengisa kakhulu intsimbi iyasokola. Iiprofayili ze-thermal zihlukeneyo zehlabathi. Ndikhumbula ndindwendwela I-Qingdao Qiangsenyuan Technology (QSY) ixeshana emva. Eyona nto yayibalasele yayingengomthamo wabo weziko, kodwa amaxwebhu enkqubo yawo yealloyi esekwe nickel. Babeneendlela ezikhethekileyo zokulawula indawo yombethe ukulungiselela umjikelo wabo wokomisa ukungunda kweqokobhe. Elo nqanaba leenkcukacha likuxelela ukuba bakhe balwa idabi lokufunxa-kunye nerhasi-porosity ngaphambili. Ixesha labo leminyaka engama-30 ekulingeni alilonani nje; lithala leencwadi leengxaki ezisonjululweyo.
Unyango lobushushu bePost-cast yenye indawo yemigodi. Isisombululo esidibanisa la malungu ayisiyiyo 'ukuseta kwaye uyilibale' umjikelo wesithando somlilo. Ixesha phakathi koluhlu olubalulekileyo lobushushu bemvula ye-carbide linzima kakhulu. Ukucotha kakhulu i-ramp-up, kwaye ufumana isigaba se-sigma kwimida yeenkozo, ukubulala ukuqina. Kwake kwafuneka ukuba silahle yonke into eninzi yezindlu zempompo kuba iziko lomlilo laline-thermocouple engalunganga, iqhuba i-25°C epholileyo kunokuba ibonisiwe. La malungu aphumelele iitshekhi ezilinganayo kodwa aqhekeka ngenxa yoxinzelelo. Sifunda ntoni? Izatifikethi zilungile, kodwa ukuqinisekiswa kwenkqubo kuyo yonke into.
Machining: Apho ithiyori idibana neSixhobo
Ukuba ukuphosa kukutsha okulawulwayo, ukwenza i-Incoloy yimfazwe yokulwa. Isantya sokusebenza nzima siyingozi. Ungena ngokufaka okubuthuntu kancinci, kwaye ngelixa u-2mm kwi-cut, imathiriyeli iye yaqina ngaphambi kwesixhobo, ekhokelela ekuqhekekeni komphetho kunye nokugqitywa komphezulu ongalunganga. Ayithethi ngamandla ehashe; imalunga nobungqongqo kunye nokuqina okungayekeleliyo.
Inkqubo ye-CNC yala malungu ifuna ifilosofi eyahlukileyo. Awunakusebenzisa iindlela ezinesantya esiphezulu, iindlela zokupasa ukukhanya onokuthi uzisebenzisele ialuminiyam. Imalunga nesantya esiphantsi, ukondla okuphezulu, kunye nokuzibandakanya rhoqo ukuze ungene phantsi komgangatho onzima womsebenzi. Isipholisi asenzelwa ukupholisa nje; sisithambisi sokuthintela ungqameko olwakhiweyo. Ndinezona ziphumo zintle ngoxinzelelo oluphezulu ngesixhobo sokupholisa, ngokuchanekileyo ukuphula itshiphu kwaye ndiyihlambe ngaphambi kokuba iphinde itshise. Iqabane elinje QSY, kunye nemigca ye-CNC ezinikeleyo yealloyi ezikhethekileyo, ngokuqhelekileyo inale siseko esidayiweyo. Bayaqonda ukuba ukwenza machining i Inxalenye ye-Icoloy ayingomsebenzi osecaleni kwisebe labo elingenasici.
Ukukhethwa kwezixhobo kucacile-i-ceramic okanye i-carbide eneengubo ezithile. Kodwa iqhawe ekungathethwa ngalo kakhulu ngumdlalo. Ufuna ubunzima kunye namanqaku okubamba angenzi ukungcangcazela kwe-harmonic. Nayiphi na incoko ikhawuleza isebenze-yenza lukhuni umphezulu, yonakalise ipasi elilandelayo. Sakhe sachitha iintsuku ezimbini sizama ukuqonda ukuba kutheni sifumana i-taper kwi-operation elula ekruqulayo. Kwavela ukuba i-vacuum chuck yayivuza i-microscopic, ivumela i-5-micron flex. Kwiimathiriyeli ezininzi, azibalulekanga. Kwi-Incoloy 925, yajika utyando lwaphela.
I-Special Alloys Niche kunye ne-Real-World Fit
Igama elithi 'ialloys ezikhethekileyo' liphoswa ngapha nangapha ngokukhululekileyo. Kumyili woyilo, kudla ngokuthetha 'ixabiso eliphezulu nelinzima.' Kodwa kumsebenzisi wokugqibela ekusetyenzweni kweekhemikhali okanye ukuveliswa kwamandla, kuthetha 'into engaqhekeziyo emva kweenyanga ezintandathu kwi-asidi eshushu.' Eli lixabiso lengcali. Bavala loo msantsa ekuqondeni.
Ukujonga iprofayile yenkampani efana ne-QSY's, ibinzana eliphambili yindibaniselwano: ukubunjwa kwegobolondo, ukuphosa utyalo-mali, kunye nomatshini we-CNC we-alloys ezikhethekileyo. Idityaniswe ngokuthe nkqo ukuntsokotha. Kuthetha ukuba banokuthatha udonga olunzima kakhulu, olubhityileyo Inxalenye ye-Icoloy uyilo-uthi, intloko ye-swirl burner eneziteshi zangaphakathi-yiphose ngotyalo-mali ukuya kwimilo ekufutshane, emva koko ugqibezele ubuso obubalulekileyo bokutywina kwi-CNC, yonke iphantsi kophahla olunye. Izinto eziphathekayo azikhe zithunyelwe phakathi kwe-Foundry kunye nevenkile yomatshini, enciphisa umngcipheko wosulelo kwaye, okona kubaluleke kakhulu, igcina ulwazi lwenkqubo luqhubekayo.
Ndikhe ndajongana nenye indlela: indlu yokuphosa igxeka ivenkile yomatshini ngokubangela uxinzelelo, ivenkile yoomatshini igxeka indlu ephoswe ngamabala anzima. Liphupha elibi. Ukudibanisa kuyayinqumla loo nto. Ivumela ukuphonononga impendulo. Mhlawumbi oomatshini bafumanisa ukuba iflange ethile isoloko ilukhuni kakhulu ukusika ngokufanelekileyo. Banokuhamba babuyele kwiqela labasunguli kwaye bacebise uhlengahlengiso kumjikelo we-annealing yaloo geometry ethile. Yigolide esebenzayo.
Ukungaphumeleli njengoMsebenzi wokunyanzelisa
Awuzifundi ngokwenene ezi mathiriyeli de kwaphuke into. Olunye ukusilela kwethu kwezemfundo yayiyisethi yeetreyi zokunyanga ubushushu ezenziwe kwi-Incoloy 601. Isicelo sasichanekile: ukuthwala iinxalenye ngesithando somlilo se-carburizing. Baphila isinye kwisithathu sobomi obulindelweyo, behexa kakubi. Uhlalutyo lubonise ukuba siyichazile ingxubevange ngokuchanekileyo yokumelana ne-oxidation, kodwa asikuhoyanga kwaphela amandla okurhubuluza phantsi komthwalo kwelo qondo lobushushu lithile. Sasikwintsapho efanelekileyo yezinto eziphathekayo, kodwa ibakala elingalunganga. I-601 ilungile, kodwa kumthwalo oqhubekayo kolu luhlu, i-DS (isisombululo esiphindwe kabini) i-800H yayiza kuba yifowuni.
Apha kulapho iitshati zokukhetha imathiriyeli yegeneric zisilela khona. Bakuxelela into echasene nokubola, hayi into ebambe imilo phantsi kobunzima bayo kwi-2100 ° F kwiiyure ezingama-5000. Olu hlobo lwe-nuance yinto oyihlawulayo kunye nomenzi onamava. Bayenze impazamo ngokwabo okanye babone umthengi eyenza. Xa ndibona umthengisi edwelisa ngokucacileyo iintsapho ezifana ne-cobalt-based kunye ne-nickel-based alloys, kubonisa ukuba baziqhelile ezi ncoko. Bayazi ukuba umbuzo awukho nje Ngaba ungayenza? kodwa Ngaba iya kusinda apho iya khona?
I-Takeaway: yiNtsebenziswano, hayi ukuThenga
Ke, xa ukhangela i Inxalenye ye-Icoloy, awuthengi nje i-hunk yentsimbi. Uthengela umthengisi amava aqokelelweyo kunye ne-thermal dynamics, utshintsho lwesigaba se-metallurgical, kunye ne-physics yomatshini okhohlakeleyo. Umzobo sisiqalo nje. Owona msebenzi ukwincoko yababini: Yeyantoni le? Yintoni umjikelo we-thermal? Ngaba kukho uxinzelelo lwebhayisikile? Umthengisi olungileyo uya kubuza le mibuzo. Enkulu, efana nezo zineengcambu ezinzulu ekujuleni nasekusebenzeni ezi rhamncwa, ziya kucebisa ezinye iindlela ongakhange uzithathele ingqalelo-utshintsho oluncinci lweradiyasi ukuphucula ukuhamba okusalayo, ukuphumla kokunyamezela okonga iiyure ezingama-20 zoomatshini, inqanaba eliphantsi le-Incoloy.
Ekugqibeleni, inxalenye efika kwi-dock yakho ibubungqina baloo ntsebenziswano. Asiyonto yorhwebo. Sisiqwenga sobunjineli esisonjululweyo, sikhenkcezwe kwi-alloy enenkani, eluncedo ngendlela emangalisayo. Injongo kukuba loo nxalenye ithembeke ngendlela engenakuthelekiswa nanto enkonzweni kangangokuba wonke umntu uyayilibala intlungu efunekayo ukuze ayenze. Kulapho uyazi ukuba wenze kakuhle.
