Ubona 304 yonke indawo. Kuyinto ezenzakalelayo, ukuya, insimbi engagqwali abantu abaningi abacabanga ngayo. Kodwa kulapho okulele khona ugibe lokuqala – sicabanga ukuthi kuyafana. Ishidi elicacisiwe lithi 18% chromium, 8% nickel, ukumelana nokugqwala okuhle, yada yada. Esitolo, phansi, yilapho nje isiqalo. Uhlamvu lwangempela lwe-304 luziveza ngaphansi kwethoshi, ku-lathe, noma ngemva kwezinyanga eziyisithupha endaweni egudle ugu. Kuyihhashi elisebenzayo, kepha elingenangqondo uma ungahloniphi ama-quirks alo.
Ukukhohlisa Okwanele Nokukhethwa Kwezinto Ezibalulekile
Angikwazi ukubala ukuthi iklayenti licele kangaki okuthi 304 ngenxa yokuthi ayinasici futhi ilingana nesabelomali, kuphela ingxenye ehlulekayo endaweni enolaka oluncane ebingahloselwe yona. I-classic iyisebenzisela i-hardware yasolwandle ngaphandle kwe-passivation efanele. Izobhoboza, futhi uma i-pitting iqala, i-slide eyehlayo. Leyo ngxube engu-18/8 imelana nohlu olubanzi lwama-oxidizer, kodwa ama-chloride? Leso isithende sika-Achilles. Ngibone umuhle 304 insimbi engagqwali abakaki kudokhi baphenduka isiphithiphithi esinamachashaza ngaphansi konyaka. Isifundo kwakungesikho ukuthi 304 kubi; wukuthi isicelo besingalungile. Kwesinye isikhathi, udinga ukuphusha u-316, noma ngabe kubiza kakhulu ngaphambili.
Kulapho-ke ulwazi olunephothifoliyo yezinto ezigcwele lubalulekile. Endaweni efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), lapho bebambe khona yonke into kusukela kunsimbi ewugqinsi kuya ku-nickel alloys amashumi eminyaka, ukukhetha akukhona nje insimbi ngokwayo. Kumayelana neketango lenqubo. Ingabe lokhu ukulingisa okuzokwenziwa ngomshini kamuva? Ngoba indlela i-304 eziphatha ngayo ekubunjweni kwegobolondo ngokumelene nesikhunta sokutshala imali yehlukile, futhi lokho kuthinta isu lomshini kamuva. Idizayini yesango, izinga lokupholisa - konke kushiya isigxivizo seminwe esakhiweni sokugcina sokusanhlamvu uchwepheshe wemishini azozizwa lapho ethatha ukusika kokuqala.
Ngikhumbula iphrojekthi yokucubungula ukudla okuhlukahlukene. Ukuphrinta kubize i-304, i-investment cast. Kubukeke kuqondile. Kodwa iklayenti lalidinga isibuko esiphelele eziteshini zangaphakathi ukuze zihlanzeke. Indawo efana ne-cast evela kunqubo evamile ibingeke iyinqamule. Kudingeke ukuthi silungise ukwakheka kwe-ceramic slurry kanye nomjikelezo we-de-waxing ukuze sithole ukuqedwa okucolisekileyo kokuphuma kwesikhunta, okonga amahora okupholisha okukhathazayo kwangaphakathi. Yilolo hlobo lwe-nuance oyifundayo ngokwenza, hhayi etafuleni lempahla ebonakalayo. Iwebhusayithi ethi https://www.tsingtaocnc.com iklelisa okukhethekile kwabo, futhi yileyo combo - ukusakaza KANYE nemishini ye-CNC - ebavumela ukuthi babone lokhu kuncika ngokucacile.
Machining 304: The Gummy Reality
Khuluma nanoma yimuphi uchwepheshe wemishini mayelana ne-304, futhi cishe bazobubula. Akuyona into enzima kakhulu, kodwa isebenza-nzima njengompetha. Ungena ngethuluzi elibuthuntu kancane, noma uvumela ithuluzi ukuthi lihlale isekhondi elihlukanisayo, futhi usanda kwakheka indawo eqinile yetshe ezohlafuna iphasi yakho elandelayo. Ukhiye unolaka futhi ubukhali. Amazinga aphezulu okuphakelayo, isivinini esiphansi kwesinye isikhathi, futhi ungalokothi uvumele ithuluzi ukuthi lihlikihle. I-Coolant ayixoxiswana, futhi hhayi nje ukupholisa - idinga ukugcoba ukuvimbela umkhawulo owakhelwe phezulu.
Lokhu sikufunde kanzima eqoqweni lemizimba yama-valve. I-geometry yayinebhobo elijulile, elinobubanzi obuncane. Konke bekuhamba kahle kwaze kwashaya isikhathi sokugcina. Ukuchezuka kwethuluzi, kuncane njengoba kwakunjalo, kubangele ukuhlikihla okwanele ukuze kusebenze-kuqinise indawo. Ithuluzi elilandelayo laphuka. Kudingeke ukuthi sishintshele ethuluzini lereki elikhethekile, eline-engeli eliqinile le-helix kanye nokupholisa ithuluzi ukuze siphushe ama-chips aphume ngamandla. Ixazulule inkinga, kodwa yadla emaphethelweni. Kuyisenzo sokulinganisa phakathi kwezindleko zamathuluzi, isikhathi somjikelezo, nezinga le-scrap.
Yilapho izinsiza ezididiyelwe zikhombisa khona ukubaluleka kwazo. Ngenxa yokuthi i-QSY iphatha imishini ye-CNC yasendlini ngemva kokusakaza, ingakwazi ukuthuthukisa inqubo yokusakaza ukuze yenze umsebenzi ube lula. Isibonelo, bangase balungise ukwelashwa kokushisa kwe- 304 insimbi engagqwali ukusakaza ukuze kuzuzwe iphrofayili yobulukhuni obungaguquguquki futhi obuphathekayo kuyo yonke ingxenye, okuthile isitolo somshini esizimele esithola ukulingisa okuluhlaza besingeke sibe namandla okulawula phezu kwayo. Lowo mbono ophelele uvimbela amakhanda amaningi ku-spindle.
Ukucatshangelwa kokusakaza: Okungaphezu Kokuncibilika Nje
Ukuthela u-304 akufani nokuthela insimbi ye-carbon. Konke kumayelana nokulawula amakhemikhali kanye nomkhathi. Ngisho ne-carburization encane evela endaweni yesikhunta ingaqeda i-chromium phezulu, ibeke engcupheni ukumelana nokugqwala lapho uyidinga khona kakhulu. Ekwenziweni kwesikhunta segobolondo, i-QSY egxile kukho, izinhlelo zokuhlanganisa i-resin zingaba luqili. Udinga inqubo eshisa ihlanzekile ngaphandle kokushiya izinsalela zekhabhoni.
I-Shrinkage ingesinye isilo. 304 inenani elibalulekile lokushwabana. Uma isistimu yakho yokudla kanye ne-gateing ingaklanywanga kahle, uzothola ukushwabana kwe-porosity, ngokuvamile kufihlwe ngaphakathi. Ingase idlule ekuhlolweni okubonakalayo, kodwa yehluleke ngaphansi kwengcindezi noma ibonakale njengendlela evuzayo. Sake saba nendlu yephampu eyaphumelela kukho konke ukuhlolwa kobukhulu kodwa yavuza ngesikhathi sokuhlolwa kwe-hydrostatic. I-Radiography yembula inethiwekhi yomgodi wokushwabana omncane, oxhumene. Ukulungiswa kwaba ukuhlelwa kabusha okuphelele kwezikhuphukeli nokubandayo. Yengeza isisindo ekubumbeni (izindleko zempahla ezengeziwe) kodwa kwakuwukuphela kwendlela yokuqinisekisa ukuzwakala.
Bese kuba khona ukulungiswa kokushisela. Ama-specs amaningi avumela ukulungiswa okuthile kwe-weld kuma-castings. Kodwa nge-304, kufanele uhlinzwe. Okokufaka ukushisa kushintsha i-microstructure endaweni ethinteke ukushisa. Uma unganakile, ungayazisa indawo, uyenze ithambekele ekugqwaleni kwe-intergranular. Kwesinye isikhathi, kungcono ukulahla iphutha elincane kunokulishisela bese udala iphuzu elingase lihluleke esikhathini esizayo. Le kholi yokwahlulela ivela ekuboneni amakhulukhulu abalingiswa bedlula ku-QC.
I-Alloy Vala Izingcingo nokuthi Kungani 304 Endures
Ngawo wonke lawa ma-nuances, kungani i-304 ihlala ivame kangaka? Izindleko nokutholakala, ngokuqinisekile. Kepha futhi, ngohlelo olukhulu lwezinhlelo zokusebenza zezimboni nezentengiso, lusebenza ngokweqiniso. Ukuphushela kwezinye izinto ezifana ne-304L (ikhabhoni ephansi) ivumeleke ezingxenyeni ezizoshiselwa kakhulu, njengoba ikhabhoni ephansi inciphisa ubungozi bokuzwela. Kodwa ezingxenyeni eziningi, izinga elingu-304 lanele ngokuphelele uma licutshungulwe ngendlela efanele.
Ngibambe iqhaza kumaphrojekthi lapho saphikisana khona izinsuku ezingama-304 ngokumelene no-316L, ngenza izivivinyo zokugqwala kumakhuphoni oketshezi lwesevisi olulingiswayo. Kwesinye isikhathi imiphumela ibisondele kakhulu ukuthi ishayelwe ucingo, futhi isinqumo sehlele izindleko zomjikelezo wempilo kanye nezici zokuphepha. Kwesinye isikhathi, sasibheka ibanga lokuphathelene lemishini 304 insimbi engagqwali izinhlobonhlobo ezine-sulphur eyengeziwe noma i-selenium. Basebenza njengephupho, kodwa ukumelana kwakho nokugqwala kuthatha ukushaya, futhi ukushisela kuba yinkinga. Kuhlala kuwukuhwebelana.
Yilokho okuwumongo wokukhethwa kwezinto ezibonakalayo ekusebenzeni. Akuvamile ukuba kube impendulo ecacile, yencwadi yokufunda. Iwuchungechunge lokuvumelana phakathi kwezidingo zemishini, izidingo zokugqwala, ukwenziwa, kanye nezindleko eziphelele. Okuhlangenwe nakho kwenkampani kuzo zonke izinqubo ezihlukene, njengeminyaka engu-30 yokusakaza nokwenza imishini ephawulelwe i-QSY, yakha umuzwa walokhu kuhwebelana. Uthuthukisa umuzwa wokuthi kufanele unamathele nini ku-18/8 yakudala nokuthi uqondise nini iklayenti ku-alloy ekhetheke kakhulu, noma ngabe iphuma emndenini ofanayo. Umgomo awukona ukusebenzisa izinto ezingavamile, kodwa ezifanele kakhulu inhloso. Futhi ngokuvamile, ngezilawuli zenqubo ezifanele kanye nokuqwashisa ngedizayini, i-304 iyona kanye leyo.
Umcabango wokugcina: Indaba inguzakwethu
Ekupheleni kosuku, insimbi engagqwali engu-304 ayiyona nje impahla. Yimpahla enobuntu. Awukwazi ukuvele uwuphonse emdwebeni bese ulindela imiphumela ephelele. Kufanele uhlanganyele nayo. Idizayinelwe ukushwabana kwayo. Umshini onemvelo yawo ye-gummy engqondweni. Cacisa ukwelapha okungaphezulu njengokudlula ukuze uvule amandla ayo okugqwala aphelele. Bese ukhetha umenzi noma umsunguli oqonda lobu budlelwano.
Ukubheka uhlu lwamakhono omhlinzeki kuxoxa indaba. Uma ubona ukwakhiwa kwesikhunta segobolondo, ukutshala imali, kanye nemishini ye-CNC konke ngaphansi kophahla olulodwa, njenge-QSY, kuphakamisa ukuthi kungenzeka ukuthi babambene nalokhu kusebenzelana kwenqubo yezinto ezibonakalayo esitezi sesitolo. Kungenzeka ukuthi babonile ukuthi i-tweak encane emjikelezweni wokusakaza ithinta kanjani ukusebenza kwe-a 304 insimbi engagqwali isihlalo se-valve. Lolo lwazi olusebenzayo, oluxhunywe iketango yilona oluhlukanisa umphakeli wezingxenye nozakwethu wokukhiqiza.
Ngakho-ke ngokuzayo lapho ucacisa i-304, dlulela ngale kwezinga le-ASTM. Cabanga ukuthi izokwenziwa kanjani, izosikwa kanjani, nokuthi iyohlala kuphi. Yilapho ubunjiniyela bangempela buqala khona. I-data sheet yisethulo; phansi esitolo yilapho ujwayelana khona ngempela.
