Xa abantu abaninzi besiva 'utyalo-mali olungenasiphelo', baba nomfanekiso wenxalenye egqibeleleyo, emenyezelayo, elungele ukusetyenziswa. Yeyona nto ifanelekileyo yokuthengisa. Inyani, ukugaya imihla ngemihla, imalunga nokulawula umsantsa phakathi kwaloo nto ifanelekileyo kunye nefiziksi yentsimbi etyhidiweyo kunye namaqokobhe eceramic. Ayikokufumana nje ukwakheka 'okungatyiwanga'; imalunga nokulawula lonke uhambo ukusuka kwi-wax ukuya kwinxalenye egqityiweyo ukuze uxhathiso lwendalo lwe-corrosion lungaphazanyiswa ngumngxuma wokushwabana ofihlakeleyo, ukuqukwa kwe-slag, okanye ubume benkozo eyingxaki. Ndibone iiprojekthi ezininzi kakhulu zikhubeka ngokujolisa kuphela kwibakala lemathiriyeli kwiphepha elithile, ukutyeshela ama-nuances enkqubo achaza ngokwenene ukusebenza.
Umdlalo weShell: Ngakumbi kuneMngundo nje
Iqokobhe liyinto yonke. Sisithuba esibi esichaza inxalenye yakho yokugqibela, kodwa nge utyalo-mali olungenasiphelo, indima yayo ibaluleke ngakumbi. Iqokobhe elibuthathaka linokujija phantsi kobushushu obuyi-1500°C+ yentsimbi engatyiwayo, nto leyo ekhokelela kwidimensional drift. Iqokobhe elingaqhawukiyo ibhondi ngokuchanekileyo ngexesha lenqanaba lokuthotywa kwewaxing linokubangela iintanda ezigcwala isinyithi, zenze iifins kunye nokudanyaza okuyingozi kakhulu ukucima umatshini, ngakumbi kwizinto ezintsonkothileyo ezinodonga olubhityileyo. Oku sikufunde kabuhlungu kwangethuba ngeqela lemizimba yevalvu. I-viscosity ye-slurry yacinywa ziinwele, nto leyo eyakhokelela kwidyasi yokuqala eyayingqindilili kakhulu. Kwabonakala kulungile de waxing, apho ukothuka thermal kubangele micro-crazing. I-316L etyhidiweyo yafumana zonke iintanda zeenwele. Isiphumo asikokusilela ekuphoseni, kodwa yintlekele yobuchwephesha. Ixesha elongezelelweyo elichithwe ekususeni umbane ontsonkothileyo, owenziwe lukhuni uliphinde kabini ixabiso leyunithi.
Kulapho amava e-Foundry abonisa khona ngokwenene. Kukwiiresiphi zokuthengisa eziludaka, ukufuma okulawulwayo kwegumbi lesicelo sestucco, kunye nemijikelo echanekileyo yokomisa phakathi kweedyasi. Ndikhumbula ndindwendwela Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ixeshana emva. Eyona nto yayibalasele yayingezoziko zabo, kodwa isebe labo lokwakha amaqokobhe. Ukuhambelana kwakuphawuleka-iqela ngalinye kwibhetshi lalibukeka lifana, uphawu lolawulo oluluqilima lwenkqubo. Kuba utyalo mali yayo nayiphi na ialloyi, kodwa ingakumbi xa kugqitywe umphezulu kudla ngokuba luphawu olubalulekileyo, oko kuhambelana kwiqokobhe kulapho umgangatho ubhakwa khona, kudala phambi kokuba kugalelwe intsimbi.
Kwakhona kufuneka utshatise inkqubo yeqokobhe kwi-alloy. Iqokobhe le-silica eliqhelekileyo elidityanisiweyo linokusebenzela intsimbi yekhabhoni, kodwa kwi-alloys ephezulu yobushushu obuphezulu okanye amabanga athile angenasici emartensitic, unokufuna idyasi esisiseko esekwe kwi-zircon ukunqanda ukusabela kweqokobhe lesinyithi, elinokubangela ukugcwala komhlaba. Yinkcukacha engenzi ukuba ifike kwincwadana ekhanyayo, kodwa luhlobo lwesigqibo esenzeka kumgangatho wevenkile. Awukwazi uku-odola nje iqokobhe.
Apho I-Stainless ifumana intsonkothe
Ukucacisa insimbi engenasici kukuphela komgca wokuvula incoko ende. Thatha i-304 iphikisana ne-316. Ubulumko obuqhelekileyo ngu-316 bungcono ukuxhathisa ukubola ngenxa ye-molybdenum. Yinyani, kodwa ngaphakathi utyalo-mali olungenasiphelo, ubumanzi be304 bungcono kancinci. Kwinxalenye enamacandelo abhityileyo ngokugqithisileyo okanye iinkcukacha ezintsonkothileyo, i-304 inokuba lolona khetho lunokukhelwa ngakumbi, kwaye ukuba imeko-bume enomhlwa yesicelo ayifuni oko, ulondoloze iindleko zemathiriyeli ngaphandle kokuncama ukusebenza. Ukutyhala u-316 kuyo yonke indawo ngenxa yokuba inqanaba eliphezulu kunokuba yimpazamo ye-rookie.
Emva koko kukho unyango lobushushu. I-As-cast stainless structures ayilunganga. Bahlala be-dendritic kwaye bahlulwe. Kwiindawo ezifuna ukuxhathisa okukhulu kwe-corrosion, unyango lwe-annealing yesisombululo esilandelwa kukucinywa okukhawulezileyo akunakuxoxisana ukunyibilikisa kwakhona i-carbides kunye ne-homogenize isakhiwo. Kodwa nanku umqobo: ukugqwetheka. I-complex, i-asymmetrical casting inokujika ngexesha lobushushu obuphezulu. Sakhe saba nendlu yempompo, intle kodwa i-cored-out casting, eyaphuma kwiziko lobushushu eliphethe i-oval kancinane. Kwakusengaphakathi kunyamezelo lomzobo, kodwa nje kancinci. Oomatshini bayithiyile kuba i-clamping yaba yinkohliso. Ngamanye amaxesha, kufuneka uyile kwaye uxhase iqela le-wax ngokwayo ngokugqwetha unyango lobushushu engqondweni, engumdaniso obuyela ngasemva phakathi koyilo, isiseko, kunye nokulungiswa kwangemva.
Umatshini ngumlamli wokugqibela. Ukuphosa kunokubonakala kugqibelele kodwa ukufihla ukuguquguquka kobunzima obutshabalalisa isixhobo sesixhobo. Iziseko ezilungileyo, njengalezo ezidityanisiweyo CNC Machining izakhono, baqonde le loop ingxelo. Bayazi ukuba imilenze yabo iyancipha njani. QSY, umzekelo, dwelisa zombini ukwenza kunye nomatshini njengowona msebenzi ungundoqo. Oko kudityaniswa kuyaxela. Kuthetha ukuba inkqubo yokuphosa inokwenzeka ukuba iphuhliswe nge-machinability engqondweni-ubunzima obungaguqukiyo, izibonelelo eziqikelelwayo zesitokhwe, kunye nokuqonda indawo yokubeka imigca yokwahlula ukunciphisa ukusetwa komatshini. Enye indlela kukuthumela ii-castings eluhlaza kwivenkile yoomatshini bomntu wesithathu, apho nasiphi na isiphene esingaphantsi komhlaba siba kukufunyanwa kweendleko kunye nomdlalo otyholwa.
Ukwandiswa kweAlloy: Xa iStainless Ayonelanga
Imigaqo ye utyalo mali iingcango ezivulekileyo ngaphaya kwamabanga asemgangathweni angenasici. Ngamanye amaxesha, isicelo siyayifuna. Siye sangena ialloys esekwe nickel njengeInconel 718 yamacandelo aphezulu obushushu. Iinkqubo ezisisiseko ziyafana, kodwa yonke into iyandiswa. Iqondo lobushushu lokunyibilika liphezulu, intsimbi ayinalwelo oluncinci, kwaye ithanda ukwahlulahlula. Iimfuno zeqokobhe zingqongqo. Iindleko zenxalenye ye-scrap yi-astronomical. Iphakamisa izibonda kwipharamitha yenkqubo nganye.
Apha kulapho iminyaka engama-30 yokusebenza inkampani ithanda QSY ucaphula uba yi-asethi ebonakalayo, hayi nje inani kwiwebhusayithi. Loo mbali ithetha ukuba babone ukusilela, bahlengahlengisa iiparamitha, kwaye bakha isiseko sedatha solwazi ngendlela yokuphatha okwahlukileyo. ialloys ezikhethekileyo. Yinkumbulo yeziko. Akukho ncwadi yesikhokelo ethi kule cobalt-chromium alloy, sebenzisa obu bushushu bangaphambi kobushushu beqokobhe ukunqanda ukungahambi kakuhle. Oko kufundwe ngolingo, impazamo, kunye namaxwebhu kumashumi eminyaka.
Nokuba ungenayo i-stainless, inyathelo eliya ngakwi-duplex okanye i-super duplex amabakala anika umdla. Banikezela ngamandla amangalisayo kunye nokumelana nokubola, kodwa badume ngobuqhetseba ukuphosa. Ibhalansi yesigaba phakathi kwe-austenite kunye ne-ferrite ibaluleke kakhulu kwaye iphenjelelwa yizinga lokupholisa. Ukukhawuleza, kwaye ufumana isakhiwo esingalinganiyo esibulala iipropati. Ifuna i-Foundry ukulawula kungekuphela nje ukugalela, kodwa yonke indawo yokuqina kunye nokupholisa ngaphakathi kwesikhunta. Linyathelo elingaphaya kwesiseko iqokobhe ngundo ukuphosa.
Izinto ezenziwayo kunye noMda oLungileyo owaneleyo
Kwihlabathi lokwenyani, ayizizo zonke iindawo ezizezenjini yejethi okanye isityalo senyukliya. Uninzi lwenzelwe ukulungisa ukutya, izixhobo zaselwandle, okanye izixhobo zekhemikhali. Injongo kaninzi kukufumana eyona ndlela ineendleko eziphezulu ukuya kwindawo eyenza umsebenzi wayo ngokuthembekileyo kubomi obucetyiweyo. Apha kulapho ukuguquguquka kwe utyalo-mali olungenasiphelo liyakhazimla. Unokudibanisa iziqwenga eziyilwe ezininzi zibe yinto enye, engenanto, entsonkothileyo. Ixabiso alikho nje kwizinto eziphathekayo, kodwa kwinxalenye yokudibanisa kunye nokunciphisa umsebenzi wokuhlanganisa kunye neendlela ezinokuthi zivuze.
Nangona kunjalo, kuya kufuneka ungabinanceba kuyilo lwakho lokuphononongwa kwe-manufacturability (DFM). Olo yilo luhle, lwendalo oluneegalari zangaphakathi lunokwenzeka, kodwa buza: ngaba kuyafuneka? Ngaba obo bukhulu bodonga bunganyuswa nge-0.5mm ukuze kuphuculwe ngokumangalisayo isivuno? Ngaba loo kona yangaphakathi ebukhali ingasasazwa ukuthintela uxinzelelo kunye nokukrazula okushushu? Iqabane elisisiseko elilungileyo liya kubuyisela umva kuyilo. Ndingalumkela omnye othi ewe, singayiphosa loo nto ngaphandle kwengxelo ye-DFM eneenkcukacha eqaqambisa iindawo ezinokuba ngumngcipheko. I-back-and-out kumzobo kulapho intsebenziswano yenziwa khona.
Ekugqibeleni, ukuhlolwa ngumgcini-sango. Ukungena kwedayi ngenxa yeziphene zomhlaba, iradiography yokuthembeka kwangaphakathi, kunye nokulungelelanisa oomatshini bokulinganisa (CMM) ukwenzela ukuqinisekiswa kwe-dimensional. Kwiindawo ezibaluleke kakhulu, unokufuna isatifikethi semathiriyeli epheleleyo (izatifikethi zokusila zealloyi, kunye neengxelo zovavanyo zoomatshini ezivela kwiikhuphoni eziphoswe ngeqela). Oku akunakuxoxwa kumashishini alawulwayo. Yongeza iindleko kunye nexesha, kodwa bubungqina bolawulo lwenkqubo. Ukuvuma kwe-Foundry kunye nokukwazi ukubonelela ngeli nqanaba lokulandeleka, ukusuka kwinyibilika ukuya kuhlolo lokugqibela, ngumahluli ophambili. Ijika ukuphosa ukusuka kwimpahla yorhwebo ibe licandelo elichanekileyo.
Ukuyisonga: Inkqubo, hayi iMveliso
Ngoko, utyalo-mali olungenasiphelo asiyonto uyithengayo nje. Yinkqubo ozibandakanya nayo. Yintsebenziswano phakathi komyili kunye nenjineli esisiseko, uthotho lokuyekelela kunye nokwenza ngcono phakathi koyilo olufanelekileyo kunye nesinyithi esisebenzayo. Amabali empumelelo avela kwiiprojekthi apho wonke umntu eqonda ukuba inxalenye ekhanyayo, egqityiweyo sisiphumo samanyathelo alawulwayo alikhulu, ngalinye lithuba lokuba into ethile ihambe kakubi. Ukungaphumeleli, kumava am, ngokuqhelekileyo kuvela ekuqhekekeni kolo nxibelelwano-ukulindela okungenangqiqo, inkcazo engayinakiyo imida yenkqubo, okanye ukhetho olwenziwa ngokuthe ngqo kwixabiso leyunithi ngaphandle kokuqonda urhwebo lobugcisa.
I-landscape inabadlali abafumana oku. Xa ujonga umnikelo wenkampani, njengokudibeneyo ukuphosa kunye nomatshini imodeli igxininiswe ngu QSY e https://www.tsingtaocnc.com, ibonisa ukuqonda kwekhonkco lexabiso lilonke. Ayikokwenza nje imilo; imalunga nokuzisa icandelo elisebenzayo, elilungele ukuhlohla. Oko kufuna ulawulo ngaphezulu kwamanyathelo enkqubo, ukusuka kwipateni yewax kunye neqokobhe ukuya kumphezulu owenziwe ngoomatshini.
Ekugqibeleni, kwehla kwintembeko eyakhelwe phezu kokungafihli kunye nolwimi ekwabelwana ngalo lokusombulula iingxaki. Ezona ziphumo zintle ndizibonileyo zihlala ziqala ngencoko ehambayo, Nantsi into esifuna ukuyenza le nxalenye. Yeyiphi eyona ndlela ilungileyo, ngokwenyani yenkqubo, yokusifikisa apho? Kulapho ubuchwephesha bokwenyani utyalo-mali olungenasiphelo ubomi.
