Xa iinjineli zichaza Ikhoneli 718, abagcini nje ngokukhetha izinto eziphathekayo-bazibophelela ekuzinzeni kwe-dimensional kwi-650 ° C, ukuchasana noxinzelelo-i-corrosion cracking kwiindawo zegesi ezimuncu, kunye nobomi bokukhathala phantsi kwe-cyclic loading thermal. Kodwa i-specs zemathiriyeli ekrwada zithetha kancinci ngaphandle kweqabane elikwaziyo ukuziphatha evenkileni. Kulapho a Umzi-mveliso we-Inconel 718 ifumana ubunzima bayo-kungekhona kwiincwadana, kodwa ngokuphindaphinda kwiibhetshi ezinamacandelo angama-200, ekuthotyelweni kwe-GD&T kwiimpawu zokunyamezelana kwe-0.005-mm, kunye nakwizinto ezothusayo zero ngexesha lokuhlolwa kwenqaku lokuqala.
Kutheni “Ifektri” ibaluleke ngaphezu “koMboneleli” we-Inconel 718
Siye sabona iiprojekthi ezininzi kakhulu zivaliwe ngenxa yokuba inkampani yokurhweba ifumene i-Inconel 718 bar stock kwi-mill enye, iphathwe ngobushushu kwisithando somlilo somntu wesithathu, emva koko iyithumele kwivenkile ye-CNC ngaphandle kokujonga i-metallurgical. Isiphumo? Ukwahluka kweMicrostructure phakathi kobushushu. I-decarburization yomphezulu kwiiflange ezijikiweyo. I-warpage ye-residual-induced warpage emva komatshini wokugqibela-ifunyenwe kuphela ngexesha lovavanyo lwe-hydraulic. Yinyani Umzi-mveliso we-Inconel 718 umnikazi wekhonkco: ukulandelelwa kwemathiriyeli ekrwada eqinisekisiweyo, isisombululo sangaphakathi sendlu kunye nemijikelo yokuguga, kunye neeparamitha zemachining eziqinisekisiweyo kweyona nto i-Inconel 718-hayi i-generic nickel-alloy presets.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke icandelo le-Inconel 718 liqala nge-AMS 5662-certified billet, eqinisekisiwe nge-PMI kunye ne-OES ngaphambi kokungena kwimveliso. Asilukhupheli ngaphandle unyango lobushushu. Iziko zethu zokufunxa zilandela ngqo iilogi zokulinganisa i-AMS 2750E pyrometer-kwaye sigcina iirekhodi ezipheleleyo zembali yobushushu kwiqashiso ngalinye. Oku akukho ngaphezulu. Yindlela esibamba ngayo i-±0.01 mm kwi-320-mm-diameter ye-piston yendlu yesilinda yempompo ngelixa sigcina i-Ra 0.4 µm umphezulu wokugqitywa kumhlaba wokutywina wangaphakathi.
Apho uMatshini oMgangatho usilelayo-kwaye yintoni kanye esebenzayo
Ezinye iivenkile ziphatha i-Inconel 718 njengentsimbi eqinileyo eqinileyo. Abayenzi. Izinga layo lokuqina lomsebenzi liyi-3 × ngaphezulu kwe-316SS. Amazinga okutya ahla nge-40% emva kokupasa kokuqala. Ubomi besixhobo buyehla ukuba uxinzelelo lwesipholisi luwela ngaphantsi kwe-70 bar. Sifunde oku ngendlela enzima yokwenza imilomo ye-AMS 5387 ye-cobalt-nickel yoxinzelelo oluphezulu lwe-hydraulic manifolds-de satshintshela kuxinzelelo oluphezulu ngokusebenzisa i-spindle yokupholisa, ukufaka i-ceramic-coated carbide kunye ne-rake geometry echanekileyo, kunye neendlela eziguquguqukayo eziguquguqukayo ezinciphisa ixesha lokuhlala.
Indawo yethu ehambelana ne-ISO iqhuba amaziko e-5-axis machining axhotyiswe kwi-deep-cavity milling ye-contours eyinkimbinkimbi-njengeendlela ezihamba nge-tapered flow valves ngaphakathi kwee-valve zoxinzelelo ezilinganiswe kwi-bar ye-420. Sidibanisa unyango lobushushu * phakathi * imisebenzi xa kufuneka: umatshini rough → isisombululo anneal → ukudambisa uxinzelelo → ukugqiba umatshini → ubudala lukhuni. Ukutsiba olo landelelwano kubeka umngcipheko wokugqwetheka okanye amandla angaguqukiyo esivuno. Abathengi abatsiba uphononongo lobunjineli bahlala bebuza, "Kutheni ibhetshi yethu yokuqala iphumelele iCMM kodwa ingaphumeleli kuvavanyo?" Impendulo inqabile umzobo-yindlela ye-thermal-mechanical.
I-Cast + Machine = iNtsebenzo yokwenyani yehlabathi onokuthi uyilinganise
I-Inconel 718 ayenziwanga nje okanye yenziwe. Kumaziko amakhulu, abaluleke kakhulu—iziseko zempompo, iirola zeshafti ezikwiziko le-winch, iivalve ezikude nonxweme—utyalo-mali luzisa imilo ekufutshane nenetha ngokuqukuqela okuziinkozo okugqwesileyo. Kodwa ukuphosa yedwa akwanele. Umphezulu we-As-cast akanako ukumelana nokudinwa okufunekayo kumalungu ajikelezayo. Yiyo loo nto wethu Umzi-mveliso we-Inconel 718 idibanisa utyalo-mali kunye nokugqiba kwe-CNC ngokuchanekileyo: ukuphoswa kwi-± 0.3 mm, emva koko ubuso bokutywinwa komatshini, iijenali ezithwele, kunye neefom zentambo ukuya ku-±0.008 mm kunye nokuqinisekiswa okupheleleyo kwe-GD&T.
Sigcina ulungelelwaniso lobugcisa kunye nabanikezeli bezinto eziphathekayo ekulawuleni ubungakanani bengqolowa (ASTM E112), ukulinganiswa kokufakwa (ASTM E45), kunye nomxholo we-delta-ferrite. Yonke into yokuphosa ifumana ukuhlolwa kwe-radiographic (ASTM E94) kunye novavanyo lokungena kwamanzi (ASTM E165). Akukho ngaphandle-nakwiprototypes. Kuba kwi-oyile kunye negesi okanye ukusetyenziswa kwe-subsea, iqela elinye le-porosity kwindawo yokunyuka koxinzelelo "ayisiyontlukwano encinci." Kukungaphumeleli kwentsimi elindele ukwenzeka.
Ukukhetha i-Inconel yakho ye-718 Partner: Izinto ezintathu ezingaxoxiswanga
Ngaphambi kokusayina i-PO, buza le mibuzo-kwaye ufune ubungqina:
- Ngaba ungandibonisa iilog zakho ezintathu zokugqibela ze-Inconel 718 zokuphatha ubushushu? Akunjalo nje amagophe obushushu—kodwa ukwakheka kwe-atmosphere ye-ournace, iremp rates, amaxesha okufunxa, namazinga okupholisa nge-AMS 2750E nganye.
- Ngaba uyayenza i-post-heat-treat microstructure verification? Senza i-SEM/EDS kwi-cross-sections ukuqinisekisa ukuba γ′ ukuhanjiswa kwesantya kunye nokungabikho kwe-δ-isigaba kwimida yengqolowa.
- Liliphi ixesha lakho elibi kakhulu lokuhamba kwe-15-part order ye-220-mm-diameter ye-cylinder yezindlu-kunye ne-certs epheleleyo yezinto eziphathekayo, iingxelo ze-CMM, kunye neerekhodi ze-NDT? Impendulo yethu ziintsuku ezingama-28 zekhalenda. Hayi "iiveki ezi-4-6." Hayi "kuxhomekeke." Siyilandelela ngexesha lokwenyani.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayizibeki njenge "Inconel 718 factory" yokuthengisa. Sibanye—kuba yonke imihla, oomatshini bethu bahlengahlengisa ukutya okusekwe kwidatha yokwenyani yokunxiba isixhobo, iimetallurgists zethu zijonga ukuqina kofundo ngokuchasene neziphumo zovavanyo lokuqina, kwaye iqela lethu le-QA lisayina kuphela emva kovavanyo olusebenzayo luhambelana nemijikelo yomsebenzi ochaziweyo ngabathengi. Lowo ngumahluko phakathi kokukhangela kunye nokusombulula.
Ukuba iprojekthi yakho elandelayo ifuna i-Inconel 718 iinxalenye ezisinde kwiiyure ze-10,000 kwi-600 ° C, itywina ngokuthembekileyo kwi-bar ye-400, okanye ujikeleze ngaphandle kokukhathazeka kwi-1,800 rpm-qalisa kunye neqabane elithembekileyo lihlala kwiilogi zabo zomlilo, kungekhona i-tagline yewebhusayithi yabo. Ilungelo Umzi-mveliso we-Inconel 718 ayithembisi imfezeko. Inika uqikelelo-indawo enye enyangwa ngobushushu, echanekile, nenxalenye enokulandeleka ngokupheleleyo ngexesha.
