Uma uzwa 'izingxenye zemishini yensimbi engagqwali ye-Sanicro 28,' umcabango osheshayo uvame ukugxumela 'ku-super austenitic, ukumelana nokugqwala okuphezulu, okulungele izindawo ezinokhahlo.' Leyo yinkulumo yencwajana. Kuworkshop, indaba imayelana nokuphatha okulindelekile—le alloy akuyona intonga yomlingo. Ixazulula izinkinga ezithile, zokugqwala okukhulu, kodwa ukwakhiwa kwayo, ikakhulukazi ukulinganisa okuyinkimbinkimbi nezinto eziwumshini, kwethula isethi yezinselele amashidi edatha ajwayelekile angakulungiseleli kuzo. Igebe phakathi kwezakhiwo zayo zethiyori kanye neqiniso lokuyiguqula ibe umzimba wevalvu othembekile, othwala ingcindezi noma i-pump casing yilapho isipiliyoni, futhi ngezinye izikhathi izifundo ezibizayo, kungena khona.
Isithembiso se-alloy vs. Iqiniso le-The Machinist
Ephepheni, Sanicro 28 uyakhazimula. I-nickel ephezulu, i-chromium, kanye nokuqukethwe kwe-molybdenum kuyinikeza ukumelana ne-pitting, ukugqwala kwe-crevice, kanye nokuqhekeka kokugqwala kwengcindezi kuma-chloride nemidiya ene-asidi. Sikhuluma phesheya kwezilwandle, ukucutshungulwa kwamakhemikhali, ukuchithwa kwegesi ephuma emanzini—izinto ezimbi. Ngikhumbula iphrojekthi yesistimu yokupholisa amanzi olwandle ehlukahlukene lapho izingxenye ezingu-316L zazihluleka phakathi nezinyanga. Iklayenti linqume ukuthi i-Sanicro 28 izongena esikhundleni. Ukweqa ukusebenza kwakungenakuphikwa; lezo zingxenye zisasebenza. Kodwa ukufika lapho kwakungaqondile.
Isithiyo sokuqala yizinga layo lokuqina komsebenzi. Kuyaphinyiswa. Uma uhlelo lwakho lwe-CNC nendlela yamathuluzi ikuthatha njengokujwayelekile 304 noma 316, uzosha ngokufaka, ubangele ukushisa okudlulele, futhi kungenzeka usebenze wenze lukhuni indawo uze wenze amaphasi alandelayo abe nzima. Udinga ukusethwa okuqinile, amajiyometri e-positive rake, futhi kufanele ngokuphelele ugcine ukuphakelayo okungaguquki, okulawulwayo kanye nesivinini. Vumela ithuluzi ukuthi lihlale, futhi usanda kwakheka indawo eqinile engase iqalise ukuqhekeka kamuva. Kuyinto edinga inhlonipho kanye nokuthintwa okulula, okucijile.
Bese kuba khona i-chip enezintambo. Ayinqamuki kahle. Ngaphandle kokulawula amashiphu okulungile—ngejiyomethri yamathuluzi, isipholile esinengcindezi ephezulu, noma ukupeyinta okuhleliwe—ugcina usunesidleke senyoni esingonakalisa indawo yokusebenza noma, okubi nakakhulu, sibangele ukuphahlazeka komshini. Sifunde lokhu kusenesikhathi ekukhiqizeni inqwaba yamaflange angokwezifiso I-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD.,(QSY). Iminyaka yabo engamashumi amathathu ekulingiseni nasekukhiqizeni imishini yayisho ukuthi bayakuqonda ukuziphatha kwezinto ezibonakalayo, kodwa nalapho, ukudayela amapharamitha aphelele ejiyomethri entsha, eyinkimbinkimbi kwakuyinqubo yokuhlola nephutha phansi esitolo. Ukusebenzisana bekuyisihluthulelo; isipiliyoni sabo se-Foundry esinezici zokuqinisa ingxubevange yazisa indlela yethu yokwenza imishini.
Izingqinamba Zokusakaza: Lapho I-Microstructure Ibalulekile
Yilapho i- izingxenye zemishini uhambo luqala ngempela ezingxenyeni ezifana nemizimba yama-valve noma ama-impeller. Indlela yokulingisa ye-Sanicro 28 ihlukile. Ithambekele ekuhlukaniseni okuncane kwezinto ezihlanganisiwe, ikakhulukazi i-molybdenum, ngesikhathi sokuqina. Uma ukupholisa kungalawulwa ngendlela efanele—yisho, ohlelweni lokutshala imali lokho QSY igxile kakhulu—ungathola ukusatshalaliswa okungalingani kwalezi zici ezibalulekile. Lokhu akuthinti nje ukumelana nokugqwala endaweni; kuthinta izakhiwo zemishini ngokufanayo.
Isibonelo: sake sathola ukusakazwa kwesixhumi esibucayi. Iphumelele ukuhlola okujwayelekile kwe-PMI (Positive Material Identification). Kodwa ngaphansi komthwalo ovivinyweni, yehlulekile ngaphambi kwesikhathi ezingeni lengcindezi elibonakala lilungile. Ukuhlaziywa kwe-Metallurgical kwembula imvula encane ye-carbide eduze kwemingcele yokusanhlamvu esigabeni esasiphole kancane. Ikhemistri eyinqwaba yayilungile, kodwa i-microstructure yasendaweni yonakaliswa. Siyini isifundo? Ku-Sanicro 28, ukulawulwa kwenqubo ye-Foundry—i-gating design, izinga lokushisa elithelayo, ukushisa kwangaphambi kwesikhunta, kanye nokwelashwa kokushisa kwangemva kokusakazwa (isixazululo se-annealing and quench)—akusona nje isinyathelo; kuyisici esichazayo sengxenye yobuqotho. I-Foundry efana nengemuva https://www.tsingtaocnc.com ebala ama-alloys akhethekile ngokusobala kungenzeka ilwe nalawa manuances, ithuthukisa izinqubo zobunikazi ukuze kuqinisekiswe ukufana.
Ukwelashwa kokushisa kwangemva kokusakazwa akuxoxiswana ngakho. Akusona isinyathelo uma kudingeka. Ukubunjwa kufanele kube yisixazululo esinamathiselwe kumazinga okushisa aphezulu (cishe u-°C ngokuvamile) bese kucishwa ngokushesha ukuze kuncibilike noma yiziphi izigaba zesibili futhi kugcinwe zonke lezo zinto ezibizayo zengxubevange kusixazululo esiqinile. Noma yikuphi ukuchezuka lapha, futhi uvaleleka ebuthakathakeni ngaphambi kokuthi umshini uqale ngisho nokuqala. Empeleni ukhokhela i-premium alloy kodwa uthola ukusebenza kwe-sub-par.
I-Welding and Fabrication Tightrope
Abaningi insimbi engagqwali imihlangano idinga i-welding. Nge-Sanicro 28, ukushisela kuyisiyalo ngokwakho. Okuqukethwe kwayo kwe-alloy ephezulu kusho ukuthi kulula ukwenza izigaba ze-intermetallic yesibili endaweni ethinteke ukushisa (HAZ) uma okokufaka ukushisa kungalawulwa ngokuqinile. Lezi zigaba, njengesigaba se-sigma, zingabhubhisa ngokuphelele ukuqina nokumelana nokugqwala endaweni.
Senza ulayini wegumbi elikhulu, elishiselwe. Ama-welds abukeka emuhle, adlulile ekuhlolweni kokungena okubukwayo nodayi. Kodwa enkonzweni, ithuthuke ukuvuza eduze kwe-HAZ, hhayi insimbi yokushisela ngokwayo. Umlandu? Okokufaka ukushisa okudlulele ngesikhathi sokudlula imanuwali yokulungisa i-TIG, engazange ibhalwe phansi enqubweni. Yakha ibhande elincane lezinto ezibolile ezagqwala ngokushesha. Ukulungiswa kwakuhilela ukufaneleka kabusha kwayo yonke inqubo yokushisela (i-WPS) ngezilawuli eziqinile kuzinga lokushisa eliphakathi nendawo kanye nokusebenzisa insimbi yokugcwalisa ene-nickel ephezulu, efana ne-Alloy 625 noma isigcwalisi esifanayo se-Sanicro 28, ukuze kulondolozwe iphrofayela yokugqwala. Kuyisikhumbuzo sokuthi amandla okokusebenza ancike kubuqotho bayo yonke inqubo yokushisa edlulayo.
Lena enye indawo lapho ukubambisana nomhlinzeki wesevisi ephelele kubalulekile. Inkampani ephethe kokubili ukusakaza/umshini futhi eqonda izinqubo zokujoyina ezansi nomfula inganikeza ukuqhubeka okubalulekile. Bangakwazi ukweluleka ngedizayini yokwenziwa—njengokuphakamisa ushintsho oluncane lwedizayini ukuze kuncishiswe ivolumu yokushisela noma ukuthola izindawo zokushisela kude nezindawo ezinengcindezi ephezulu—ngokusekelwe endleleni okokusebenza okuziphatha ngayo kulo lonke iketango.
Izindleko-Inzuzo: Ukuqinisekisa I-Premium
Masikhulume ngokungagwegwesi: Izingxenye ze-Sanicro 28 ziyabiza. Izindleko zempahla eluhlaza ziphezulu, ukukhanda kuhamba kancane futhi kusebenzisa amathuluzi abizayo, futhi izilawuli zekhwalithi ezidingekayo zengeza phezulu. Awuyicaciseli ukuzijabulisa. Ukulungiswa yizindleko eziphelele zomjikelezo wokuphila endaweni edla ezinye izinto.
I-matrix yesinqumo iyasebenza. Ingabe iyindawo emile, eyonakele kancane? 316L kungenzeka kwanele. Ingabe i-chloride stress corrosion iyingozi enkulu? Mhlawumbe i-duplex 2205 inikeza ibhalansi engcono yamandla-ukugqwala ngezindleko eziphansi. Kodwa uma ubhekene nokushisa, i-sulfuric acid egxilile, i-phosphoric acid ene-fluoride, noma amanzi olwandle ane-chlorination, futhi udinga i-ductility enhle kanye nokushisela phezu kokumelana, leyo yi-Sanicro 28 niche. Ingcweti, hhayi i-generalist.
Kumakhi, lokhu kusho ukuba nezingxoxo eziqotho namakhasimende. Ukuhlehlisa isicaciso esibonakala singaphezu kwamandla, kodwa futhi siyimela lapho uhlelo lokusebenza lugunyaza ngempela. Ngibone amaphrojekthi lapho izindleko zangaphambili zibangele ukushaqeka kwesitikha, okuholela ekwehliseni kwenani elishibhile. Eminyakeni emibili kamuva, izindleko zesikhathi sokuphumula, ukushintshwa, kanye nokugcinwa kwemvelo ngenxa yokwehluleka kwanciphisa ukonga kwasekuqaleni. Inani langempela le-a I-Sanicro 28 insimbi engagqwali ingxenye ayikho entweni yomugqa we-oda lokuthenga; kusekusebenzeni kwayo okuthulile, okuthembekile iminyaka eminingi endaweni lapho kungekho okunye okubambelelayo.
Ukuthola Nokubambisana: Isici Esingabonakali
Awukwazi ukuvele uthenge lezi zingxenye kukhathalogi. Ukukhiqiza Izingxenye zemishini ye-Sanicro 28 ukusebenzisana kwezobuchwepheshe. Lapho uhlola umphakeli, awubheki nje imishini ye-CNC; uhlola ukuqonda kwabo kwe-metallurgical. Ingabe bayakuthola ukubaluleka kwamashadi okwelapha ukushisa? Ingabe banganikeza imibiko yokuhlaziywa kwe-micrographic? Ngabe omashini babo bayawuqonda umuzwa wendaba?
Yingakho ulwazi lomkhiqizi olushiwo, njengengemuva le-QSY leminyaka engu-30 ekusetshenzisweni kokutshalwa kwezimali kanye nomshini wama-alloys akhethekile, linesisindo. Kusikisela inqolobane yolwazi oluthulile—uhlobo olukhumbulayo ukuthi yimuphi umklamo wesango onciphise isiyaluyalu ngokusakazwa kwengxubevange ye-Ni-based efanayo, noma yikuphi ukwakheka kokupholisa okusebenze kangcono kakhulu ukuphatha ukunamathela kwe-chip. Iwebhusayithi yabo, https://www.tsingtaocnc.com, ibala ingxubevange ye-cobalt ne-nickel eceleni kwe-stainless, okuwuphawu oluhle; iphakamisa ukujwayelana nawo wonke umndeni wezinto zokwakha eziyinselele, ezisebenza kahle kakhulu.
Ubudlelwano buba ubambiswano lwezobuchwepheshe. Imiphumela engcono kakhulu engiyibonile ihlanganisa ukwabelana ngemininingwane egcwele yendawo yesevisi (izinga lokushisa, ukugxila kwamakhemikhali okunembile, imithwalo yamabhayisikili) nomsunguli kanye nochwepheshe bemishini. Lokhu kuzivumela ukuthi zenze izinguquko ezicashile—mhlawumbe ukulungisa kancane esikhathini sokuvala isixazululo, noma izincomo zokuqeda okuthile ukuze kuncishiswe ingozi yokuqalisa umgodi. Ingxenye iba yisixazululo esenziwe ngokubambisana, hhayi nje impahla ethengiwe. Emhlabeni wama-alloys asezingeni eliphezulu, lokho kujula kokuhlanganyela kuvamise ukuba umehluko phakathi kwengxenye ehlangabezana nje nokuphrinta naleyo ehamba kahle kakhulu kusevisi.
