Xa iinjineli zichaza 410 intsimbi engenasici kumandla aphezulu, amacandelo aphathwa ngobushushu-njengemizimba yevalvu ye-hydraulic, izindlu zempompo, okanye i-winch shafts-ayikhethi nje into. Bazibophelela kwiqabane lokuvelisa eliqondayo indlela i-410's martensitic structure eziphatha ngayo phantsi koxinzelelo, indlela ukuxhatshazwa kwayo okulinganiselweyo kufuna ulawulo oluchanekileyo lomphezulu, kwaye kutheni i-batch-to-batch hardness ibaluleke ngaphezu kwamanani e-tensile yedwa.
Kulapho amava ahlula khona ababoneleli kwiifektri. Nge QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., senze oomatshini abangaphezu kwe-12,000 410 yentsimbi engenasici kwiindibano zempompo ye-oilfield yaseMntla yaseMelika ukususela ngo-2021-nganye ifuna i-Rockwell C42-48 ubulukhuni emva kokucima kunye nokutshisa, ± 0.015 mm ukunyamezela kwejometri ebusweni bokutywinwa, kunye nokulandelwa okupheleleyo kwi-ASTM ye-A276 yezinto eziluhlaza. Siye sabona abathengi begatya iinxalenye ngenxa yokuqhekeka kancinci kufutshane neefayili ezibukhali emva konyango lobushushu-kwaye bafunda ukuguqula iindlela zesixhobo kunye nemijikelo yokutshisa kwangaphambili ngokufanelekileyo. Siye sabona abathengi bengayihoyi into yokuba umxholo we-nickel ophantsi we-410 uwenza uvakale ekuhlaselweni kwe-intergranular kwiindawo ezityebileyo ze-chloride ngaphandle kokuba igqitywe ngokuchanekileyo. Le ayingombhalo osemazantsi wencwadi. Ziizifundo zasendle ezibhakwe kuyo yonke into 410 umzi-mveliso wentsimbi inkqubo esiyiqhubayo.
Ukuchaneka akukhethi-kwakhiwe kwindlela yokuziphatha ye-alloy
I-410 yensimbi engenasici ihambisa amandla ngokuguqulwa kwe-martensitic-kungekhona iifilimu ze-chromium oxide. Oko kuthetha ukuba ukusebenza kwayo kuxhomekeke kwizinto ezithathu ezidityaniswe ngokuqinileyo: ukwakheka kweekhemikhali (ingakumbi ikhabhoni kunye ne-chromium balance), imbali yobushushu, kunye nokugqiba koomatshini. Isiqinisekiso sokusila esisemgangathweni asiqinisekisi ukuqina okungaguqukiyo. Sifumana iibhilithi ezingama-410 eziqinisekisiweyo kwi-AMS 5504 kwaye siqinisekisa ubushushu ngamnye nge-OES spectroscopy phambi komatshini. Ukuba i-carbon drifts ngaphezu kwe-0.15%, silungisa amazinga okucima. Ukuba i-chromium yehla ngaphantsi kwe-11.5%, sifaka iflegi ibhetshi-nokuba idibana nobuncinci be-ASTM-kuba ihlabathi lokwenyani linxiba ubomi.
Sidibanisa unyango lobushushu ngokuthe ngqo kwi-CNC yethu yokuhamba komsebenzi. Iinxalenye zisuka kumaziko ojiko ziye kwiziko lokufunxa ngaphantsi kwemizuzu engama-90—akukho kuvezwa kwe-ambient. Ukucima kusebenzisa igesi yenitrogen kwisantya esilawulwayo, hayi i-oyile okanye amanzi, ukuphelisa iingozi ezigqwethekileyo kwizindlu ezinemibhobho ebhityileyo. Ukufudumala kwenzeka kwiiyure ezi-4 zokucima, kungekhona iintsuku kamva. Ngoba? Ngenxa yokuba i-austenite egciniweyo iguqula ngokungalindelekanga ngaphaya kwefestile, iphosa ubunzima bokugqibela kunye nozinzo lwe-dimensional. Eli nqanaba loqeqesho lwe-metallurgical alunakuxoxisana xa inxalenye yakho itywina kwi-3,000 psi okanye ijikeleza phantsi kwemithwalo ye-winch yeetoni ezili-15.
Udibaniso oluthe nkqo lusombulula ukuba yintoni ikhefu lokuthengisa ngaphandle
Abanye ababoneleli bangaphandle bephosa, ukwenza machining, kunye nonyango lobushushu ukwahlula abathengisi. Oko kudala iindawo ezingaboniyo: i-Foundry ayizazi ii-callouts zakho ze-GD&T; isixhobo sokufudumala asikwazi ukubona iimfuno zakho zokugqiba umphezulu; umgqibi ufumana iinxalenye ezinemilinganiselo engahambelaniyo okanye i-decarb layers. Singabanikazi bazo zontathu izigaba-kwindawo enye eqinisekisiweyo ye-ISO 9001 eQingdao.
- Iyaphosa: Izindlu ze-Sand-cast ze-410 kunye nokulawulwa kokuqina kolwalathiso-ukunciphisa i-porosity ye-shrink kwiindawo zomthwalo onzima nge-62% ngokubhekiselele kwi-molds eqhelekileyo
- Umatshini: Amaziko e-CNC e-5-axis anenkqubo yokuphanda echanekileyo yokukhula kwe-thermal ngexesha lokusika okude kwi-120-mm-diameter piston bores.
- Ukugqiba: Imiphezulu yombane ifezekisa iRa ≤ 0.4 µm kwindawo yokutywina-ingqinwe ngeeprofilometers, hayi uqikelelo olubonakalayo
Oku akukho malunga nokulula. Imalunga nokuthintela iindlela zokungaphumeleli ukuba akukho mthengisi umnye umnikazi wawo: isiphene sokuphosa esigqunywe sisitokhwe soomatshini, ukunyanga kwe-warp engalunganga yonyango njengempazamo yokulungisa, okanye ifilimu ekhutshiweyo ngexesha lokugxothwa. Xa uodola kwinyani 410 umzi-mveliso wentsimbi, ufumana iqela elinye elijongene nekhonkco lonke-ukusuka kwintsimbi etyhidiweyo ukuya ekuqinisekiseni ukusebenza.
Ukuqinisekiswa kwehlabathi lokwenyani koyisa iinkcazo zephepha ngalo lonke ixesha
Sivavanya iindawo ezingama-410 njengabasebenzisi bokugqibela-kungekhona nje kwimigangatho ye-ASTM, kodwa kuxinzelelo lwesicelo. Yonke indlu yevalve yoxinzelelo ivavanywa ngobungqina be-hydrostatic kwi-1.5 × yoxinzelelo olulinganisiweyo, kunye nokuhlolwa kwedayi kuzo zonke iindawo zokulungisa i-weld. Yonke i-winch centre shaft roller iqhuba umjikelo wokunxiba okhawulezileyo weyure ezingama-72 ngokuchasene nokuqina kobuso be-42CrMo4-ukulinganisa ilahleko enkulu, utshintsho olurhabaxa lomphezulu, kunye nobunzulu bobunzima obuncinci. Singena iziphumo ngenani leqashiso ngalinye. Ufumana idatha-kungekhona nje "ukudlula / ukungaphumeleli" isitampu.
Abathengi bahlala bebuza: "Ngaba ungabamba ±0.005 mm kwi-shaft engama-300-mm-ubude be-410?" Ewe—kodwa kuphela ukuba siwumatshini ngokweendlela ezimbini zokuseta: vula ngokurhabaxa kwi-lathe eqinileyo, emva koko ugqibezele ukugaya emva kokunciphisa uxinzelelo kwi-650°C. Siza kukuxelela kwangaphambili. Asiyi kucaphula unyamezelo esingakwaziyo ukubamba kwiiyunithi ezingama-500. Kwaye ukuba umzobo wakho ubiza i-radius ye-0.2-mm apho uvakalelo lwe-notch ye-410 lufuna i-0.5 mm-siya kukubonisa itshathi ye-fracture mechanics kwaye sicebise utshintsho ngaphambi kokusika isinyithi.
Ukuthembeka kwi-410 yensimbi engenasici iqala ixesha elide ngaphambi kokuba i-chip yokuqala ihambe. Iqala ngokwazi ukuba i-alloy iphendula njani-kungekhona ukuba imele iphendule njani. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke into 410 umzi-mveliso wentsimbi umyalelo njengentsebenziswano yesinyithi. Sinikezela ngamacandelo achanekileyo. Kodwa okona kubaluleke kakhulu, sihambisa ukuqikelela-ubukhulu, oomatshini kunye nokuhanjiswa. Ngenxa yokuba iinkqubo ezibaluleke kakhulu zobuthunywa azisileli kwizinto ezimbi. Bayasilela kwiinguqu ezingalawulwayo. Kwaye ezo ziguquguqukayo zihlala kwiinkcukacha esizilawulayo.
