Uma onjiniyela becacisa insimbi engagqwali engu-310S yezindwangu zesithando somlilo, ama-nifold exhaust, noma amavalvu ezinga lokushisa eliphezulu, abagcini nje ngokukhetha into ethile—babheja ukuzinza kwesakhiwo esincane esingaphezu kuka-1,000°C. Kodwa nakhu okutholwa amaqembu amaningi okuthenga sekwephuze kakhulu: akuyona yonke imboni ye-310S yensimbi engagqwali eletha ukwakheka okusanhlamvu okungaguquki, ukusatshalaliswa kwe-carbide, noma ukumelana nokukhathala okushisayo-ngisho nezitifiketi ezifanayo zokugaya. Sibone ukulingwa kwe-310S okuphethwe ukushisa kuqhekeka ngemva kwemijikelezo engu-200 ku-1,150°C—hhayi ngenxa yedizayini, kodwa ngenxa yokuthi ukuhlukaniswa kwe-dendritic ye-as-cast akuzange kuhlanganiswe ngokugcwele ngaphambi kokuhlanganisa isixazululo.
Kungani Ukungaguquguquki Kwezinto Kubaluleke Kakhulu Kunezitifiketi Zokugaya Zodwa
Umbiko wokuhlola umshini wokugaya uqinisekisa ukwakheka kwegama. Kuyenzeka hhayi iqinisekisa ukusatshalaliswa okufanayo kwe-chromium-nickel yonkana odongeni lokulingisa oluwugqinsi luka-400-mm. Emkhiqizweni womhlaba wangempela, silinganisele ukuncipha kwe-Cr okungu-8% ezindaweni ezi-interdendritic ze-sand-cast 310S—okwanele ukuqalisa i-oxidation yendawo ku-1,050°C. Kungakho abasebenzisi abaholayo manje bafuna izingodo zokwelashwa kokushisa okulandelekayo, hhayi nje ukuhlaziywa kwamakhemikhali. Imboni ehamba phambili ye-310S yensimbi engagqwali ihlanganisa ukusakaza, ukuvala isixazululo, kanye nokudambisa ingcindezi ibe ukulandelana okukodwa okulawulwayo—azikho izihlambi zokushisa zangaphandle, azikho iziqephu zenqwaba. Esikhungweni sethu e-Qingdao, yonke indawo engu-310S ifakwa isixazululo esiphindwe kabili: okokuqala ku-1,060°C ukuze kuncibilike ngokuphelele i-carbide, bese ipholisa kancane ibe ngu-750°C bese ishisisa kabusha ibe ngu-920°C ukuze i-spheroidize isigaba se-sigma esiyinsalela. Lokhu akuwona umkhuba ojwayelekile—indlela esibamba ngayo izinga lokugqwala kwe-intergranular elingaphansi kuka-0.02 mm/ngonyaka ekuchazweni okushisayo okujikelezayo.
Amakhono Amathathu Angaxoxiswana Kufanele Uwaqinisekise
Ngaphambi kokugunyaza imboni ye-310S yensimbi engagqwali, qinisekisa lawa makhono amathathu—esayithini, hhayi nge-imeyili:
- Ukuqinisekiswa kwe-metallurgical okuphansi: Ingabe basebenzisa i-optical emission spectroscopy (OES) kukho konke ukushisa? Bangakwazi yini ukudonsa isampula engxenyeni ewugqinsi kakhulu yokulingisa kwakho—hhayi nje umgijimi wokungena?
- Ukwelashwa kokushisa komkhathi okulawulwayo: Ingabe ukuthungatha kwenziwa ezithandweni zengxube ye-nitrogen-hydrogen ezinamazolo ≤ -40°C? Ukuvuza komoya ngesikhathi sokupholisa kudala isikali se-chromium oxide esibukela phansi ukumelana nesikali sesikhathi eside.
- Ukuqinisekisa ukuzinza kwe-Dimensional: Ezingxenyeni ezingaphezu kuka-300 mm, ingabe ziyakala i-warpage ngemva ukwelashwa ukushisa-hhayi ngemva nje komshini? Silungise umnsalo ongu-0.8 mm eringini yokushisa engu-310S ngokuhlanekezela kusengaphambili iphethini, bese siqinisekisa nge-laser tracker ngemva komnyaka.
Lapho Amakhathalogi Ajwayelekile Ehluleka—futhi Ubunjiniyela Bangokwezifiso Buwina
Ama-flange e-off-the-shelf 310S asebenza kahle ku-850°C. Kodwa uma uhlelo lwakho lokusebenza ludinga ukuhamba ngebhayisikili okungu-1,100°C ngama-syngas agcwele isibabule, ama-generic specs ayahlukana. Yilapho udinga umlingani ophatha i-chemistry njengesiqalo-hhayi umugqa wokugcina. Kumakhasimende aseYurophu amavalufu e-biomass gasifier, silungise ukuncibilika kwe-310S: sanyusa i-silicon yaba ngu-1.8% ukuze kuthuthukiswe ukumelana ne-slag, sehlise i-manganese yaba ngu-0.4% ukuze sicindezele ukwakheka kwe-delta-ferrite, futhi sengeza u-0.15% we-cerium ukuze uphine imingcele yokusanhlamvu. Umphumela: 3.2× impilo yesevisi ende uma iqhathaniswa ne-ASTM A297 Ibanga HK40. Asikho isitifiketi esifaka lokho—kodwa ukuhlolwa komhlaba wangempela kuyakwenza.
Okufanele Ukubuze Ngaphambi Kokuthumela I-PO Yakho Yokuqala
Ungabuzi ukuthi "Ungakwazi ukwenza i-310S?" Buza esikhundleni salokho:
- “Ngibonise amamephu amathathu okugcina e-EDS e-310S ewugqinsi kuno-250 mm—ikakhulukazi isixhumi esibonakalayo phakathi kwesikhuphukeli nokulingisa.”
- "Isiphi isikhathi sakho esiphezulu sokubamba phakathi kwe-shakeout kanye ne-annealing yesisombululo sendlu engu-120-kg 310S?" (Impendulo kufanele ibe amahora angu-≤ 4)
- “Ingabe uyazigcina izibonelo eziqinile kukho konke ukushisa—futhi ngingayicela idatha yomthelela kaCharpy ku-1,000°C?”
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. igcina ukulandeleka okugcwele ukusuka kulogi ye-ladle ukuya embikweni wokugcina we-CMM. Lonke i-oda le-310S lihlanganisa izitifiketi zempahla yokusetshenziswa, amashadi okwelapha ukushisa, nezithombe ze-metallographic zesigaba esiwugqinsi—ezitholakala ngaphambi kokuthunyelwa. Isizinda sabo esithobela i-ISO siqhuba utshalomali kanye nokusakazwa kwesihlabathi ngapha nangapha, okubavumela ukuba bakhethe inqubo enciphisa ukuthambeka okushisayo ezindaweni ezibucayi. Kumajiyometri ayinkimbinkimbi afana nama-multi-port exhaust manifolds, zisebenzisa i-hybrid casting-machining: i-rough-cast near-net shape, bese izindawo zokuvala umshini we-CNC ziye ku-±0.05 mm ngemva kokukhululeka kwengcindezi—ukuqeda ukuhlanekezela kokuphathwa kokushisa.
Bheka Ngale Kwesitifiketi—Bheka Indawo Eyaphukile
Ukuhlolwa kwangempela kwemboni yensimbi engagqwali engu-310S akuwona amaphepha ayo. Ukuthi izindawo zayo zokuphuka zibonisa okuhlanzekile, okusanhlamvu okulinganayo—hhayi ama-dendrites ahlukanisiwe noma amanethiwekhi esigaba se-sigma. Uma uthola isampula yakho yokuqala, cela ingxenye ephambanayo epholishiwe odongeni olusinda kakhulu. Ngaphansi kokukhuliswa okungu-100×, kufanele ubone usayizi wokusanhlamvu ofanayo (ASTM 4–6), uqhekeko oluyiziro, futhi awekho amabhande aphelelwe yi-chromium. Leyo isiginesha yomhlinzeki ophatha i-310S hhayi njengensimbi yempahla—kodwa njengengxenye yesistimu yokushisa enembayo. Njengoba amaphrojekthi omhlaba ecindezela amazinga okushisa okusebenza aphezulu, lowo mehluko uhlukanisa ozakwethu abathembekile ekubaleni kabusha okubizayo. Ngokuzayo uma ucacisa i-310S, ungamane uhlole ishidi elicacisiwe. Hlola i-microstructure.
