Xa usiva i-N06625, okanye i-Inconel 625 njengoko abantu abaninzi kumgangatho wevenkile beyibiza, into yokuqala ethi qatha engqondweni idla ngokuba 'bubushushu obuphezulu' okanye 'i-corrosion resistant'. Ngumgibe oqhelekileyo lowo. I-nuanced kakhulu kunoko. Ndibone iiprojekthi zivaliwe ngenxa yokuba umntu othile uyicacisile ecinga ukuba yinto enye-ilingana-yonke into ephezulu kuyo nayiphi na into enobundlobongela. Ayiyo. Ibali lokwenyani kukuziphatha kwalo ngexesha lokwenziwa kunye naphantsi kweemeko ezithile zenkonzo, kungekhona nje kwi-database. Umtyholi, njengesiqhelo, ukwiinkcukacha zokusebenza ngokwenene nayo.
Ukujongwa kweNyaniso yoKwakha
Masithethe ngomatshini. Nabani na oqhuba i-lathe okanye ilitye ku-625 uyayazi imvakalelo yokuqala ethi 'oh, oku kusikeka kulungile' kunika imbeko. Isebenza-nzima. Ukukhawuleza. Ukuba awuzifumani iifidi zakho kunye nezantya kanye ukusuka ekuqaleni, awupheleli nje uguge into yokufaka; wenza umaleko womphezulu nzima kangangokuba ukupasa okulandelayo kube liphupha elibi. Ndiyifunde le ndlela inzima kwangethuba, ndizama ukuthabatha isikali sokugqiba kwishafti ejikiweyo kuphela ukuze ndibe nesixhobo sokutyibiliza kwaye sitshise umphezulu. Inxalenye yayisisilaphu. Udinga ukuseta okuqinileyo, iijiyometri zehariki ezilungileyo, kunye nokuziphatha ukugcina isixhobo sisebenzisana kunye nokusika, hayi ukuhlikihla. Ukupholisa? Yikhukulise. Ayisenzelwanga ukuthambisa kakhulu ukutsala ubushushu kude kwindawo esikiweyo ukunciphisa isiphumo sokuqina.
Kulapho ukusebenzisana nevenkile enemigama yokwenyani kwezi zixhobo kwenza umahluko. Ndijonge umsebenzi osuka kwiindawo ezifana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY). Ukugxila kwabo ixesha elide kwi CNC Machining ii-alloys ezikhethekileyo aziyondawo yembumbulu nje. Ungayibona kumaphepha enkqubo yabo - bangena kwiinkcukacha zeendlela zesixhobo ialloys esekwe nickel ukulawula ubushushu kunye noxinzelelo, yiloo nto kanye i-625 ifuna. Kukuqonda okubonakalayo okuvela ekwenzeni iinxalenye, hayi nje ukucaphula kuzo.
Emva koko kukho ukuwelda. Isigaba selaves. Yiloo boogeyman for 625 welders. Igalelo lobushushu elininzi kakhulu, okanye isigcwalisi esingafanelekanga, kwaye ufumana ezi khompawundi ze-brittle intermetallic kwi-weld zone. Ndikhumbula umbhobho wenqanawa yoxinzelelo apho i-weld yadlula yonke into ebonakalayo kunye ne-X-reyi kodwa yasilela kuvavanyo loxinzelelo. I-Microanalysis ibonise ukubunjwa kwe-laves. Ulungiso lwalungelokutshintsha nje iiparamitha; yayitshintshela kwintsimbi yokuzalisa ngokuthe ngqo elungeleleneyo ukucinezela olo kwakheka, njenge625 Plus. Yongeza iindleko, kodwa yayingumahluko phakathi kokulungiswa kunye nokusilela kwintsimi. Esi sixhobo sikufundisa ukuba isiqinisekiso senkqubo asiyonkqubo; ngundoqo wemfezeko.
Ngaphaya KokuMhlwa: Ubucacileyo boMsebenzi
Ewe, iqaqambile kwiindawo ezine-oxidizing. Kodwa ukusebenza kwayo inkwenkwezi, ngokombono wam, kukuxhathisa i-chloride-ion stress-corrosion cracking (SCC). Sasisebenzisa kwishafti zempompo zamanzi ebrackish apho i-316L yayiza kuqhekeka ngexesha lonyaka. Kodwa nantsi i-nuance: oko kuxhathisa akunasiphelo. Ndibone i-pitting iqala phantsi kweemeko ezimileyo, ezimdaka apho i-chlorides ixinana khona. I-alloy yaxhathisa ukuqhekeka, kodwa sisafumana uhlaselo lwasekhaya. Sifunda ntoni? Ukukhethwa kwezinto eziphathekayo lukhetho loyilo lwenkqubo. Usadinga ukuqwalasela ukuhamba, ukucoca ukufikelela, kunye nokuyidibanisa kunye nezixhobo ezifanelekileyo zokutywina.
Amandla ayo obushushu obuphezulu yenye indawo yokungaqondi kakuhle. Abantu bajonga kwi-1000 ° F+ amanani e-tensile kwaye bacinga ukuba yeyamacandelo ashushu kwiiinjini zomoya. Ngelixa isetyenziswa apho, i-niche yayo ihlala iyindawo ephakathi- yithi, iisistim zokukhupha okanye ukulungiswa kobushushu-apho ufuna amandla alungileyo okurhubuluza kodwa kunye nokuxhathisa okumangalisayo kwe-oxidation. Umxholo wechromium wenza ukuba uzinzile, isikali esikhuselayo. Sasisebenzisa iityhubhu ezikhazimlayo kwiziko elitshisayo. Baye bagqithisa izinto zangaphambili ngomlinganiselo wesithathu, kungekhona ngenxa yokuba bomelele kwiqondo lobushushu, kodwa ngenxa yokuba bengazange balinganise kwaye bathobe isidima. Imowudi yokungaphumeleli itshintshile ukusuka ekuncipheni kancinci kancinci ukuya ekudinweni okuthe gqolo kokuqhekeka emva kweminyaka emininzi yenkonzo.
Oku kudibanisa emva kwicala le-Foundry. Iimpawu zokuphosa ze N06625 zi… ngokukodwa. Iqhelekile kwi-microporosity kunye nokwahlula ukuba i-temp yokugalela kunye ne-mold preheat ayilawulwa ngokuqinileyo. Ivenkile eyenza utyalo mali okanye iqokobhe ngundo ukuphosa ngale ngxubevange ngempumelelo hayi nje ukugalela isinyithi; balawula idrama yobushushu ukusuka kwiziko ukuya kwi-shakeout. I QSY iwebhusayithi ikhankanya umsebenzi wabo kunye ialloys ezikhethekileyo, ebandakanya ngokufihlakeleyo eli nqanaba lolawulo lwenkqubo. Xa ukhangela icandelo le-625, uthenga iprothokholi ye-thermal ye-Foundry.
Ikhonkco loNikezo kunye neQuirk yokuQubeka
Ukufumana i-625 bar engaguqukiyo okanye ipleyiti kulula ngoku kuneshumi leminyaka eyadlulayo, kodwa kufuneka ubukele iicerts zemill njengokhetshe. Ayisiyiyo nje ikhemistri, kodwa yeyomsebenzi oshushu kunye nembali yokucoca. Sakhe safumana ipleyiti edibana ne-AMS kunye ne-ASTM specs ephepheni kodwa yabonisa ukwahluka kwasendle kubuchule kubude bayo. Uphando lwalatha kwi-anneal engalinganiyo yokugqibela kwindawo yokusila, eshiya ezinye iindawo ezinobunzima, ubume obuncinci be-ductile. Isixhobo sokusila siyenze yalunga, kodwa yasixabisa iveki yokuphumla. Ngoku, asikhankanyi nje umgangatho, kodwa amaxesha amaninzi indlela ethile yokuqhubela phambili okanye umvelisi okhethiweyo wezicelo ezibalulekileyo.
Ukuyibumba kubanda yibhere. Ine-springback ephezulu. Ukuba uyayigoba, uyigoba ngaphezulu kwesixhobo kwaye unethemba lokuba iya kubuyela kwi-spec. Kwimilo entsonkothileyo, ukubumba okushushu kudla ngokuba yeyona ndlela iphilileyo. Senze imivumbo yokwandisa ngokwesiko ukusuka kwiphepha elicekethekileyo. Umzamo wokuqala wokubanda-wasebenza loo nto kangangokuba yaphulukana ne-ductility kwaye yaqhekeka ngexesha le-hydrotesting. Isisombululo yayikukuba malunga ne-1200 ° F, efuna izixhobo ezikhethekileyo kunye nolawulo lwe-atmosphere ukuthintela i-oxidation egqithisileyo. Yayiyimeko eqhelekileyo yezinto eziyalela yonke indlela yokuvelisa.
Yiloo nto imodeli yenkonzo epheleleyo yabanye ababoneleli ibalulekile. Ukuba umthombo omnye, njengoko kukhankanywe ngasentla QSY, inokusingatha i utyalo mali ukwenza imilo ekufutshane ne-net kwaye emva koko ulandele ngokuthe ngqo CNC Machining kwi-alloy efanayo, baphelisa kakhulu ukuphathwa, ukuvunyelwa, kunye nobungozi bokulandelwa. Awuthumeli imveliso ekrwada kwivenkile yomatshini enokuthi ungayiqondi i-idiosyncrasies yayo. Ulwazi luhlala kwi-ecosystem enye.
Iindleko vs. Ixabiso: Ubalo lokwenyani
Masibe neentloni: N06625 iyabiza. Umxholo we-nickel kunye ne-niobium uyakubona oko. Ukuthetheleleka akuveli ekubeni 'kumnandi ukuba' okanye 'ipremiyamu.' Ivela kuhlalutyo olupheleleyo lweendleko-zobunini ezibandakanya ixesha lokuphumla, ukutshintshwa kwabasebenzi, kunye nezinto zokhuseleko. Sitshintshe i-carbon steel quench tank agitator shaft enye eyenziwe kwi-625. Intsimbi yentsimbi yahlala iinyanga ezi-8 kwindawo ye-caustic, i-chloride-laden. I-625 shaft isasebenza emva kweminyaka esi-7. Iindleko zangaphambili zaziyi-5x, kodwa ukuphepha ukuvalwa okuhlanu ukuyibuyisela endaweni yayo kuzihlawulele kwiinyanga ezili-18. Ixabiso likwinkonzo engapheliyo, hayi ixabiso lokuqala.
Nangona kunjalo, kufuneka ulumke ungasebenzisi kakhulu. Ayisoloko iyimpendulo. Kwimekobume engcolisekileyo apho i-2205 duplex steel stainless inokwanela, ukusebenzisa i-625 yimpazamo yezoqoqosho kwaye ngamanye amaxesha yobugcisa. I-Duplex inamandla aphezulu, ngoko ke ungasebenzisa ngaphantsi kwayo, kwaye ihlala ilula ukuyidibanisa. Ukhetho lufuna ukuphononongwa okungathandekiyo kokuvezwa kweekhemikhali, amaqondo obushushu, uxinzelelo kunye nobomi obunqwenelekayo. Ndibe yinxalenye yeeseshoni zobunjineli bexabiso apho siye saxoxa ngempumelelo ukuba sithobe ukusuka kwi-625 ukuya kwi-super duplex, ukonga i-30% kwiindleko eziphathekayo ngaphandle kwelahleko yokusebenza kwelo tyala likhethekileyo.
Oku kujikeleza emva kobuchule bomenzi. Iqabane elilungileyo alineli nje ukuthi 'ewe' kwizinto eziphathekayo. Bayayibuza. Basenokujonga umzobo wenxalenye engama-625 baze babuze, 'Ibona ntoni? Ngaba ukhe wayiqwalasela ialloyi X kweli candelo?' Loo ngxoxo, ezalwa ngamava ngamava kunye nempumelelo kunye nokungaphumeleli kwezi zinto, kulapho ubunjineli bokwenyani kwenzeka. Ngumahluko phakathi kokuthenga iqhekeza lesinyithi kunye nokuphuhlisa isisombululo.
Ukuqukumbela Ngaphandle Kwesaphetha Kuyo
Ke, N06625. Lihashe lomsebenzi, kodwa linomsindo. Ixabiso layo alizuzwa; ifunyanwa kuphela ngokuyilwa okuchanekileyo, okunolwazi kunye nokusetyenziswa okuchanekileyo. Amaxwebhu edatha akunika imida, kodwa ulwazi lwendlela ehamba ngayo phantsi kwesixhobo, ukuba sibaleka njani sibe ngumbumba, indlela esisabela ngayo phantsi kwetotshi – bubuchule obo. Yiloo nto eyahlula icandelo elisebenzayo elithembekileyo.
Xa ujonge ababoneleli, obo bugcisa buyimetric engundoqo. Ngaba banokuxoxa ngemingeni yobushushu be-interpass kwi-weld yokupasa emininzi? Ngaba banayo indlela ebhaliweyo yokunciphisa ukuqina komsebenzi ngexesha lomatshini? Kumacandelo atyhidiweyo, ngaba abonisa ulawulo kuwo wonke umjikelo wokunyibilika kokunyibilika? Ezi ziimpawu ezibonakalayo zobuchule.
Ekugqibeleni, ukusebenza nale alloy yinkqubo yokufunda eqhubekayo. Yonke iprojekthi yongeza inqaku ledatha. Ukubaleka ngempumelelo kukufundisa oko kusebenzayo. Ukungaphumeleli, okuhlala utitshala onamandla ngakumbi, kukubonisa apho imida efihlakeleyo iphi. Injongo kukwakha ithala leencwadi langaphakathi lamava, ke kwixesha elizayo i-N06625 ifika ngapha kwedesika, isigwebo sakho malunga nendlela yokuyiqhuba kunye nokuyisebenzisa ibukhali kancinane, isekelwe ngakumbi, kwaye isebenza ngakumbi. Leyo yimvelaphi yokwenyani yobuchwephesha kunye nale nto.
