Xa indlu yakho yempompo ye-hydraulic iqhekeka kwi-420 ° C, okanye umbhobho we-cobalt alloy usilela emva kweeyure ezingama-380 kwinkonzo yegesi emuncu, awujongani nengxaki yomatshini-ujongene ne Ubushushu obuphezulu be-alloy factory umsantsa wokukwazi. Siye sayibona rhoqo kakhulu: amaqela obunjineli afumana izixhobo ze-AMS 5387 ukusuka kwisiseko senjongo ngokubanzi, kuphela ukufumanisa i-microsegregation kumacandelo aphethwe ubushushu, ukuhamba okuziinkozo okungahambelaniyo kwizikhewu ezikhexiweyo, okanye ukutenxa kwe-GD&T okuphumela ekuvuzeni kwendibano. Ukusebenza kwehlabathi lokwenyani phantsi kokuhamba ngebhayisikile eshushu, uxinzelelo oluphezulu, kunye nemithombo yeendaba erhabaxa ayixoleli ulawulo lwempahla esecaleni okanye ubunini benkqubo.
Kutheni “i-High-Temp Alloy” Ingeyiyo nje ileyibhile-kukuzibophelela kwenkqubo
Ayinguye wonke umenzi wesinyithi ofaneleka njengenyani Ubushushu obuphezulu be-alloy factory. Abaninzi baphatha i-nickel-based castings-kodwa bambalwa bagcina ukulandeleka okugcweleyo kwirisithi ye-billet ye-T800 eqinisekisiweyo ngokusebenzisa i-annealing yesisombululo, i-multi-axis contouring, kunye nokugqitywa komphezulu oqinisekisiweyo we-CMM. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-cobalt-nickel alloys kungekhona njengezinto ezingaqhelekanga, kodwa njengeenkqubo ezixhomekeke kwizinto ezixhomekeke kuzo: izinga lokuqina lichaphazela ukuhanjiswa kwe-carbide; ulandelelwano lomatshini lumisela uxinzelelo olushiyekileyo kwizindlu zesilinda ezibhityileyo; Nokucima iqondo lobushushu eliphakathi litshintsha idelta phakathi kwe-ASTM A995 yeBanga le-CD4MCu kunye nokumelana nokutyiwa kokwenyani kwiindawo ezityebileyo kwi-oyile.
Sakhe saphinda sakha indlu yesilinda yempompo yepiston eyasilelayo kwiyunithi yokutofa yolwandle oluseMantla. Inxalenye yokuqala ibisebenzisa igeneric IN718 kodwa ibingenalo ulawulo lokuqina. Uhlaziyo lwethu lwazisa ukupholisa okulawulwayo ngexesha lotyalo-mali, lulandelwa yi-HIP + ukuguga kabini-kunye nokwandisa ubomi benkonzo ukusuka kwiinyanga ze-14 ukuya kwi-42. Oko kwakungeyona nje into engcono yokukhetha i-alloy. Ibiyi-casting-machining-heat treatment ulungelelwaniso akukho mthengisi-nkqubo omnye unokuzisa.
Izakhono ezine ezingaxoxisiyo ongenakukwazi ukuzikhupha ngaphandle
A ethembekileyo Ubushushu obuphezulu be-alloy factory Kufuneka ibe ngabanini ezi ntsika zine—ingabi ngabangaphandle kuzo:
- Ubugosa ngezinto eziphathekayo: Intsebenziswano ethe ngqo yobugcisa kunye nee-mills, kungekhona nje ukuthenga ii-odolo. Siqinisekisa zonke isatifikethi sobushushu se-AMS 5387 ngokuchasene ne-ASTM E112 ubungakanani beenkozo, isithuba sengalo ye-ASTM E1268 dendrite, kunye neengxelo zovavanyo lwe-batch-specific intergranular corrosion.
- Ukuphosa-ukudityaniswa komatshini: Iziseko zentsimbi ezifakwe esantini ziba nzima ngaphambi kokuba zithobe uxinzelelo. Imilomo ye-cobalt yotyalo-mali idlula emva *emva kwe-HIP-hayi ngaphambili. Oku kuthintela ukugqwetheka okutshabalalisa ukunyamezelwa kwe-positional kwi-0.015 mm yeempawu zendawo yokwenyani.
- Ukunyanzeliswa komda: Hayi nje "i-CMM-ijongiwe." Sisebenzisa i-profilometry ye-optical kwiindawo zokutywinwa, ukuqinisekiswa kwe-laser tracker kwisiseko esikhulu sempompo (ukuya kwi-2.8 m), kunye nenkqubo yokuqinisekisa i-touch-probe kwi-5-axis CNCs-kuba i-thermal drift ngexesha lomjikelo omde we-machining yecandelo elishinyeneyo le-T800 inokutshintsha i-bore concentricity nge-0.022 mm.
- Ukuqinisekiswa okusebenzayo: Yonke ivalve yoxinzelelo ivavanywa ngobungqina be-hydrostatic kwi-1.5 × yoxinzelelo olulinganisiweyo, kunye novavanyo lokuvuza kwe-helium nge-ISO 15848-2. Akukho "isampulu-kuphela" ngaphandle.
Iindleko ezifihliweyo zokufumana amaqhekeza
Abanye abathengi bahlukanise umsebenzi: ukuphosa kwi-Foundry A, unyango lobushushu oluvela kwi-Heat Treater B, ukugqiba ukusuka kwi-Machine Shop C. Kodwa xa iplagi ye-AMS 5387 iphuhlisa i-microcracks kufuphi nengcambu yentambo, ngubani ophethe unobangela? I-Foundry A ithi ulwakhiwo lwabo lwe-as-cast lwadibana ne-spec. IHeat Treater B iqinisekisa ukuba umjikelo wabo ungqamane nedatha yedatha. Ivenkile yoomatshini C ibonisa iilog zendlela yesixhobo egqibeleleyo. Ngeli xesha, iprojekthi yakho ibaleka iiveki ezintandathu.
Silandele umkhondo we-31 engaphumelelanga ukuhanjiswa kwecandelo lobushushu obuphezulu kule minyaka mithathu idlulileyo. I-68% ilandelelwa kwii-interface gaps phakathi kwamanyathelo enkqubo-kungekhona iziphene zezinto eziluhlaza. Enye indawo yokucokisa eSoutheast Asia yalile iibhetshi ezili-17 zeeplagi ze-cobalt alloy kuba umphezulu wesanti awuzange ube ngoomatshini bokususa iileyiti ze-decarburized phambi konyango lobushushu. Olo maleko lwaba yindawo ye-nucleation yokuqhekeka phantsi komthwalo we-thermal ojikelezayo. Ulawulo oludibeneyo luphelisa ezo ndawo zingaboniyo.
Yintoni omawuyifune kwiFactory yakho ye-alloy yobushushu obuphezulu-Okwangoku
Phambi kokusayina i-NDA, buza le mibuzo mihlanu-kwaye ujonge ukuba iphendula njani:
- "Sibonise izatifikethi zakho zokugqibela ze-AMS 5387-kunye nengxelo ye-post-HIP microstructure ehambelanayo kunye nohlalutyo lwe-carbide morphology."
- "Uqinisekisa njani uzinzo emva konyango lobushushu kwiindawo ezine> 3: 1 umahluko?"
- "Ngobuphi ubushushu bakho obuphezulu obuvumelekileyo bokugqitha ngexesha le-TIG ye-welding ye-cobalt ye-cobalt-kwaye uyijonga njani ngexesha lokwenyani?"
- "Ngaba unokubonelela ngomkhondo ogcweleyo wendlu enye yempompo yepiston-ukusuka kwi-ID ye-log yokunyibilika ukuya kwingxelo yokugqibela yokuhlola?"
- "Sithini isivuno sakho sokuqala sokupasa kwiijiyometri ezingekho mgangathweni ezifunekayo <0.01 mm ukunyamezela iprofayile?"
Ukuba iimpendulo azicacanga, zilibazisekile, okanye zicaphula “imigangatho yeshishini” ngaphandle kokukhankanya iindlela zovavanyo ezithile—hamba uhambe. Ukuchaneka akuxoxiswana xa kusebenza kwi-70% yendawo yokunyibilika.
Ukusebenza kwe-alloy yokushisa okuphezulu kuqala ixesha elide ngaphambi kokusikwa kokuqala okanye ukuthulula. Iqala ngoqeqesho lwe-metallurgical, lunyanzeliswa ngapha nangapha ukuphosa, umatshini, kunye nokugqiba-unganikezelwanga kwimida yesebe. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakhela udumo lwayo ekwaleni oko kuqhekeka. Indawo yayo ehambelana ne-ISO eQingdao ayenzi nje iinxalenye ezidibana nespekthi. Ihambisa izinto ezisindayo kwizinto ezingazibambiyo: ukudinwa okushushu, ukhukuliseko lwamasuntswana, i-hydrogen embrittlement, kunye nemfuno engapheliyo yexesha lokuphumla elingacwangciswanga. Xa isicelo sakho sityhala ngaphaya kwe-500 ° C, ngaphaya kwe-10,000 psi, ngaphaya kwemijikelo yomgangatho wesiqinisekiso-kulapho inyani Ubushushu obuphezulu be-alloy factory iyeka ukuba ngokuzikhethela.
