Lapho onjiniyela bayacacisa Izingxenye zemishini ye-Sanicro28 yensimbi engagqwali, abakhethi enye nje ingxubevange—bakhetha into eklanyelwe ukusinda ku-chloride enamandla, i-asidi, nezimo ezishisa kakhulu. Kodwa ukuthola okuthembekile I-Sanicro28 yensimbi engagqwali izingxenye zefekthri ozakwethu basalokhu kuyinselelo eqhubekayo. Abahlinzeki abaningi kakhulu bathembisa ukuhambisana—bese beletha ukwakheka okusanhlamvu okungaguquki, ukuqedwa komphezulu onqenqemeni, noma ukukhukhuleka okunohlangothi ngemva kokwelashwa kokushisa. Sizibonele mathupha: indlu yepompo ye-hydraulic iqhekeke kubha engu-42 ngenxa yokuthi umphakeli weqe ukuqinisekiswa kwe-annealing yesisombululo; i-valve yomjovo wamanzi olwandle yehlulekile ukuhlolwa kokugqwala ngemva kwezinyanga eziyisithupha—hhayi ngenxa yekhemistri ye-Sanicro28, kodwa ngenxa yokuthi ukubunjwa akuzange kulungiswe *futhi* kufakwe emanzini anosawoti ku-ASTM A967 Class VI.
Kungani i-Sanicro28 Idinga Okungaphezu Kokukwazi Kwensimbi Engagqwali Okujwayelekile
I-Sanicro28 (UNS N08028) ayiyona nje “insimbi engagqwali ene-nickel eyengeziwe.” I-chromium engu-27%, i-nickel engu-31%, i-molybdenum engu-3.5%, nokuqukethwe kwe-nitrogen elawulwayo kuletha ukumelana okukhethekile nokubhoboza, ukugqwala kwe-crevice, kanye nokuqhekeka kokugqwala kwengcindezi—kodwa kuphela lapho ubuqotho be-metallurgical bulondolozwa kuzo zonke izinyathelo. Lokho kusho ukuthi azikho izinqamuleli ekulandelekeni kwezinto ezingavuthiwe, akukho kuyekethisa ekulawuleni izinga lokushisa le-annealing (1120–1180°C), kanye nokungabekezeleli nhlobo ukuzwela kwe-intergranular ngesikhathi sokushisela noma ukufaka ukushisa ngomshini. Izitolo eziningi zensimbi engagqwali ezijwayelekile azinakho ukulinganiswa kwesithando somlilo, ukuqapha isimo sezulu, noma izinqubo zokudlula zangemuva komshini ezidingekayo. Bawenza ngomshini—kodwa *abawazi kahle*.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha i-Sanicro28 njengohlelo olusebenzayo—hhayi nje into ethile. Iqoqo ngalinye lifika nemibiko egcwele yokuhlolwa komshini (MTRs) eqinisekisa ukuthobela kwe-ASTM B673. Amabha angenayo athola i-spark spectrometry nokuqinisekiswa kwe-PMI ngaphambi kokusikwa. Ngesikhathi sokushintshwa kwe-CNC kwemizimba yamavalvu okucindezelayo, sikhawulela i-spindle RPM kanye nezinga lokuphakelayo ukuze sibambe izinga lokushisa lethuluzi elingaphansi kuka-300°C—ukuvimbela izendlalelo eziqiniswe ngumsebenzi ezivalela ama-chloride. Ngemva komshini, izingxenye ziqonda ngqo esithandweni somlilo esihlanzwe nge-nitrogen ukuze kufakwe isixazululo esigcwele, okulandelwa ukucisha kwamanzi ngokushesha okuqinisekiswe imephu ye-thermocouple. Akukho ukupholisa komoya. Akukho ukuxutshwa kwenqwaba. Akukho ukucabanga.
Ukuhlanganisa Okuqondile Kuxazulula Igebe Lokungaguquguquki le-Sanicro28
Amafekthri amaningi akhipha imithombo yokusakaza, ukwenza imishini, noma ukuqeda—akha izindawo lapho ukusebenza kwe-Sanicro28 kwehlisa khona. I-Foundry ingase ithulule ngendlela efanele, kodwa uma umakhi wemishini engalungiseleli i-Sanicro28's 40% ephansi ye-thermal conductivity uma iqhathaniswa ne-316 stainless, ithuluzi lokuchezuka lichitha ama-callouts e-GD&T. Uma umshini wokushisa usebenzisa umoya ongangenisi, i-chromium carbides igxuma eduze kwemingcele yokusanhlamvu—ibulala ukumelana nokugqwala.
Siyawaqeda lawo magebe. Isikhungo sethu esithobela i-ISO siphatha yonke into yasendlini: ukutshala imali kwezindlu zamasilinda ayinkimbinkimbi, ukwenziwa kwemishini ye-CNC ye-multi-axis yamaflange epompo ye-piston ano-±0.01 mm wokubekezelela indawo, kanye nokuqedwa kwe-electropolished ku-Ra ≤ 0.4 µm. Kumarola e-Sanicro28 winch center shaft, senza umumo osondelene nenethi, bese senza i-annealing ekhulula ukucindezeleka ngaphambi kokujika kanzima kokugcina—ukuqinisekisa ukuzinza kwe-microstructural ngaphansi komthwalo we-cyclic torsional. Yonke ingxenye iphethe ukulandeleka okugcwele kwempahla: inombolo yenkatho, i-MTR ID, ilogu yokwelashwa kokushisa, umbiko we-CMM, nesitifiketi sokumahhadla kwendawo.
- Amavalvu omfutho we-Sanicro28 - enziwe ngomshini asuka ku-billet emgunyathi, akalwe nge-ASME B16.34, afakwe emanzini ku-1.5× MAWP
- Izisekelo zephampu — i-sand-cast enamalugi ahlanganisiwe afakwayo, edambisa ingcindezi, kanye nomhlabathi ophansi ukuze ube flat ≤ 0.05 mm/m
- Izingxenye zomshini ze-Sanicro28 ezingajwayelekile - eziklanywe ngempendulo ye-DFM, okuhlanganisa ukuqina kodonga ukuze kunqandwe ukuklebhuka okushisayo ekubumbeni
Ukuqinisekiswa Komhlaba Wangempela, Hhayi Ukuthobela Amaphepha Kuphela
Amakhasimende ayabuza: “Ungahlangana ne-NACE MR0175/ISO 15156 ukuze uthole isevisi emuncu?” Yebo—kodwa kuphela ngemva kokuqinisekisa ukukhiqizwa ngakunye kwendlela ye-ASTM G48 A (ukuhlolwa kwe-ferric chloride pitting) kanye ne-ASTM G123 (ukuhlolwa kokugqwala kwe-crevice). Asithembeli kuma-generic alloy certs. Sihlola *ingxenye yakho*, *kwijiyomethri* yakho, sisebenzisa *indawo yesevisi oyihlosile*. Umsebenzisi oyedwa waseNorth Sea udinga ukucwiliswa amahora angu-1,000 emanzini olwandle okwenziwa ku-80°C. Silethe amasampula amathathu wokufaneleka—ngalinye lihlolwe ngokuzimela, nge-metallography yezigaba ezihlukene eqinisekisa ukuthi akukho sigaba se-sigma esakhiwe.
Leso siyalo sidlulela ku-logistics. Izingxenye ze-Sanicro28 zihamba nge-vacuum evalwe ngephepha le-VCI—elingasongwe ngepulasitiki elivalela umswakama. Amadokhumenti ahlanganisa amarekhodi okuhlola aphelele, hhayi nje isitatimende sokuvumelana. Futhi ukwesekwa konjiniyela kuqala ngaphambi kwe-PO: ithimba lethu libuyekeza i-GD&T yakho, lihlaba umkhosi okungenzeka liphazamiseke umashini ezibhodleleni ezibekezelela ngokuqinile, futhi lisikisela ukuguqulwa kwama-radiusing ukuze kuncishiswe ukugxilwa kwengcindezi—mahhala.
Ukukhetha I-Sanicro28 Yakho Yezingxenye Zensimbi Engagqwali Mechanical Factory
Uzakwethu ofanele akamane nje acaphune i-Sanicro28—uyaqonda ukuthi kungani uyikhethile. Bayazi ukuthi ukuchezuka okungu-0.02 mm ku-seal groove akukhona nje “ukungabekezelelani”—kuyindlela yokungena kwe-chloride. Abawuphathi umdwebo wakho njengohlu lokuhlola, kodwa njengemephu esebenzayo.
Uma uhlelo lwakho lokusebenza ludinga ukumelana nokugqwala okubikezelwayo, ubuqotho besakhiwo ngaphansi komthwalo ojikelezayo, nokuzinza kwe-dimensional kuyo yonke imijikelezo yokushisa—khona-ke ukunemba kubaluleke ngaphezu kwentengo. Udinga a I-Sanicro28 yensimbi engagqwali izingxenye zefekthri elawula lonke uchungechunge: impahla eluhlaza eqinisekisiwe, ukucutshungulwa kwe-thermal okulinganiselwe, ukuhlolwa kwebanga le-metrology, nokulandeleka okubhaliwe. Hhayi noyedwa ohlola amabhokisi. Lowo ovimbela ukwehluleka ngaphambi kokuthi kwenzeke.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha lezo zingxenye—nsuku zonke, kumakhasimende kulo lonke elaseYurophu, eNyakatho Melika, naseNingizimu-mpumalanga Asia. Ngoba ezimweni ezinzima, ukwethembeka akuyona inketho. Yakhiwe.
