I-investment casting steel stainless steel iletha izingxenye ezinemba ezinemba lapho ukukhanda kwendabuko kufinyelela emikhawulweni—ikakhulukazi kumajiyometri ayinkimbinkimbi, izindonga ezincanyana, noma amaphaseji angaphakathi kuma-hydraulic valves, izindlu zephampu, nezingxenye zenkundla kawoyela. Senze izingxenye zensimbi engagqwali ezingaphezu kuka-2,400 ezinyangeni eziyi-18 kuphela—futhi ngayinye ibidinga ukulawulwa kobukhulu obunamandla kuno-±0.05 mm, ukulandeleka okugcwele kwe-microstructure, kanye ne-zero porosity ezindaweni ezithwala ingcindezi. Lokho akulona ithiyori. Kungumsebenzi wansuku zonke endaweni yethu eqinisekisiwe ye-ISO e-Qingdao.
Kungani ukutshala imali kwensimbi engagqwali kwehlula ezinye izinhlelo zokusebenza ezibaluleke kakhulu
Onjiniyela abaningi bazenzakalela ku-CNC-machined 316 noma 17-4PH lapho bedinga ukumelana nokugqwala namandla. Kodwa ukwenza imishini kuqala ngesitokwe sebha esiqinile—ukumosha u-60–85% wezinto ezibonakalayo ezingxenyeni ezifana nezindlu zesilinda sephampu ye-piston ezinamabhore agxilile, amachweba ama-radial, nama-flanges asymmetrical. I-investment cast steel stainless steel iqeda lokho kumosha kuyilapho ilondoloza izakhiwo zokuwalungisa: amandla aqinile ahlala phakathi kuka-±3% ekushiseni okukodwa, ukugeleza okusanhlamvu kulandela izindlela zokulayisha ezisebenzayo, futhi ukuqedwa okungaphezulu njengoba ukusakaza kufinyelela ku-Ra 3.2 µm—ilungele ukuvala indawo ngaphandle kokugaya.
Sibone amakhasimende eshintsha kusukela ekubunjweni kwesihlabathi ukuya ekutshalweni kwensimbi engagqwali ngemuva kokuhluleka okuphindaphindiwe kuma-hydraulic manifolds womjikelezo ophezulu. Ukukhishwa kwesihlabathi kuqhekeke kuma-fillet ngaphansi kwe-35 MPa pulsation. Ukukhishwa kwe-investimenti kudlule imijikelezo engu-500,000 ku-42 MPa-ngoba iphethini ye-wax ithwebula i-radii phansi ku-0.3 mm, iqeda amakhona abukhali agxilisa ukucindezeleka. Umehluko awukona nje izimonyo. Ubuqotho be-metallurgical, buqinisekiswa nge-ASTM A743/A744 ngayinye futhi busekelwa izitifiketi zokushisa ezithize ze-batch.
Izinzuzo ezibalulekile azibonakali—ziyalinganiseka:
- Ukuphindaphinda kobukhulu: Ukuhambisana nokubekezelela okuqinisekisiwe kwe-CMM ku-99.7% kuzo zonke izindawo zokukhiqiza ezingu-12,000+
- Ukusetshenziswa kwezinto: 82% isivuno esimaphakathi vs. 28% sezingxenye ezifanayo zomshini
- Inkululeko yokuklama: Awekho ama-engeli asalungiswa adingekayo; ama-undercuts, izimbobo eziyimpumputhe, nezici zokukhweza ezihlanganisiwe kusakazwa ngokuqondile
- Ikhwalithi yobuso: Ayikho imigqa ehlukanisayo, i-flash, noma i-core shift—ibalulekile ekuxhumaneni kophawu oluguquguqukayo
Izindleko ezifihliwe zokweqa impahla kanye nokuqondanisa kwenqubo
Abanye bacabanga ukuthi noma yiliphi ibanga lensimbi engagqwali lisebenzela ukutshala imali. Akulungile. Silahle amahemuhemu amathathu e-prototype angu-2205 ngoba igobolondo le-slurry alikwazanga ukumelana nokuncipha kwalo kokuqina. Ibanga libalulekile—kodwa kanjalo nendlela oyidlala ngayo. 304 kanye no-316 ziziphatha ngokubikezela kumagobolondo asekelwe ku-silica ajwayelekile. Kodwa ama-superaustenitics afana ne-AL-6XN afuna amagobolondo e-ceramic-bonded zirconia kanye namazinga aqondile erempu yokukhipha waxing. I-317LMN eqiniswe yi-Cobalt? Idinga ukuthululwa okusizwa yi-vacuum ukucindezela umgodi wegesi.
Kungakho sihlanganisa ama-specs wezinto ezibonakalayo nabaphakeli—hhayi nje ukuthenga ama-ingots “aqinisekisiwe”. Lapho ikhasimende lase-Europe lidinga izindlu zamaphampu ezithobela i-AMS 5387 ezithobela i-AMS 5387, sihlole amaqoqo amahlanu ancibilikayo ngokumelene namajika anwebekayo ashisayo, isikhala sengalo ye-dendrite, kanye namamephu wokuhlukaniswa kwe-interdendritic. Amabili kuphela ayehlangabezana nemfuneko yokuphila kokukhathala ku-120°C. Okunye kuye kwalahlwa—hhayi i-inventory yakho, hhayi uhlelo lwakho.
Umphumela womhlaba wangempela: Iklayenti laseNingizimu-mpumalanga ye-Asia lehlise ukuhluleka kokuvuza kwe-valve ngo-94% ngemva kokusuka ekutshalweni kwezimali okujwayelekile okungu-316 kuya emkhathini wethu olawulwayo othele u-316L ngensalela ye-oxygen engu-≤12 ppm. Ukulungiswa bekungeyona idizayini entsha. Kwakuyi-metallurgy enembile, eyenziwa ngokuqhubekayo.
Yini eyenza umphakeli akwazi ngempela—hhayi nje ukuqinisekiswa
Izitifiketi zibalulekile-kodwa aziqinisekisi ukusebenza kwengxenye. Sihlola wonke umphakeli ongase abe umhlinzeki ezintweni ezine okungaxoxiswana ngazo:
- Ukulandeleka kwempahla eluhlaza: Inombolo yokushisa egcwele ingena kusuka ku-ingot kuya engxenyeni yokugcina, nokuqinisekiswa kwe-spectrographic ekuhlolweni okungenayo
- I-metrology engaphakathi kwenqubo: I-CMM ihlola amaphethini we-wax *kanye* namagobolondo—hhayi nje ukulingisa okuqediwe
- Ukuqinisekiswa kwe-Microstructure: Izigaba ezihlanganisiwe ezihlanganisiwe zibuyekezwa nge-ASTM E112 ngayinye ngosayizi wokusanhlamvu, ukusatshalaliswa kwe-carbide, nokuqukethwe kwe-delta ferrite
- Ukuhlola okusebenzayo: Ukuhlolwa kokubola kwengcindezi ku-1.5× ingcindezi yokusebenza, nokutholwa kokuvuza kwe-helium kuze kufike ku-1×10⁻⁹ mbar·L/s
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. kusebenza zozine—hhayi njengezindawo zokuhlola, kodwa njengezilawuli ezishumekiwe. Uma u-oda izingxenye zensimbi engagqwali ezitshaliwe ezivela kithi, uthola imibiko enobukhulu, izifinyezo zokuhlaziya okubonakalayo, nezithombe ze-microstructure—hhayi nje isitifiketi sokuhambisana. Ngoba idokhumenti esayiniwe ayivimbi indlu yephampu kusukela ekuqhekekeni ekuqaleni.
Izinyathelo ezilandelayo: Ukusuka ekudwebeni kuya ekulethweni, ngaphandle kwezimanga
Uma ngabe iphrojekthi yakho elandelayo ifaka utshalomali olufaka insimbi engagqwali endaweni enengcindezi ephezulu, egqokwa kakhulu, noma enamakhemikhali anolaka—qala ngokubuyekezwa kokwenziwa. Thumela iphakheji yakho ye-GD&T. Sizomaka izici ezishayela izindleko (njengezigaba zodonga ezingu-0.1 mm kokuthi 316) noma ukwenqatshwa kwengozi (ubulukhuni obungacacisiwe obuphezulu ezindaweni zokuvala). Sizophakamisa ukushintshwa kwe-alloy okuthuthukisa ukugaywa ngaphandle kokudela umsebenzi—njengokushintsha ukusuka ku-17-4PH ukuya ku-15-5PH ukuze uthole ukumelana okungcono kwezinyembezi ezishisayo kumarola e-winch shaft esigaba esincane.
Akukho ukugcinwa kwesango. Azikho izikripthi zokuthengisa. Ingxoxo nje yobunjiniyela esekelwe kulokho okusebenzayo-nokuthi yini ehlulekayo-emkhiqizweni wangempela. Uzokwazi kungakapheli amahora angama-72 ukuthi idizayini yakho izosakazwa ngokuhlanzekile, umshini ngokuthembekile, futhi usebenze ngaphansi komthwalo. Lelo jubane livela ngokwenza lokhu nsuku zonke—hhayi ngezikhathi ezithile.
Ukutshala imali ngensimbi engagqwali akuphathelene nokunethezeka. Imayelana nokuxazulula izinkinga zemishini ayikwazi ukuthinta-ngaphandle kokuhweba kude nokuthembeka. Ukunemba kwakhelwa ngaphakathi. Ukuthenjwa kuyatholwa—ukushisa okukodwa, indawo eyodwa, ukuhlolwa kwengcindezi okukodwa ngesikhathi.
