Lapho onjiniyela bayacacisa carbon steel utshalomali izingxenye casting, abagcini ngoku-oda insimbi kuphela—bafuna ukuzinza kobukhulu ngaphansi kwengcindezi ye-hydraulic yamabha angu-350, ukungaguquguquki kwe-microstructural kuwo wonke amayunithi angamayunithi angu-500, nobuqotho obungaphezulu obusinda ekugelezeni kwe-slurry okulimazayo amahora okusebenza angu-12,000. Lelo zinga lokusebenza aliveli kuma-generic foundries. Kudinga a imboni ye-carbon steel investment casting parts yakhelwe phezu kokuqondisa kwe-metallurgical-hhayi nje amandla okuphonsa.
Kungani Ukutshala Kwezimali Kuwina Ngezinsimbi Ezibalulekile Ze-Carbon Steel
Ukukhishwa kwesihlabathi kubusa ukukhiqizwa kwe-carbon steel yevolumu ephezulu-kodwa kuyahluleka lapho ubunkimbinkimbi bejometri buhlangabezana nobunzima bokusebenza. Sibone izindlu zesilinda sephampu ye-piston zinqatshwa kabili: okokuqala ngo-0.18 mm ukujiya kodonga endaweni yembobo yamavalvu, bese kuba ngenxa ye-micro-porosity eduze nezindawo ezithinteke ukushisa ngemva kokudambisa ingcindezi. Ukukhishwa kwe-investimenti kuxazululwe kokubili. Inqubo yegobolondo layo le-ceramic iletha ukubekezelela komugqa okungu-±0.05 mm ezicini ezifana namashaneli okupholisa angaphakathi nama-bores athwele agxilile—ngaphandle kwama-engeli asalungiswa noma imigqa yokuhlukanisa. Okubaluleke nakakhulu, isilawuli sokuqinisa ukuqondisa kunciphisa imigodi eshwabene ekuguqukeni okuwugqinsi kuya-kuya-mncane okuvamile emizimbeni yamavalvu okucindezelayo namarola e-winch centre shaft. Ukuhwebelana? Izindleko eziphakeme ngengxenye ngayinye. Inzuzo? Ukungasebenzi kabusha kwe-Zero kumadatha abalulekile e-GD&T. Kuzinhlelo zokusebenza lapho ukwehluleka kusho ukuthi isikhathi sokuphumula sibiza u-$18,000/ihora, leso zibalo akunakuxoxiswana ngaso.
Ubuqotho Bempahla Buqala Ngaphambi Kokuthela
Ukulingisa insimbi ye-Carbon akuphumelelanga—hhayi ngenxa yendlela yokuphonsa engalungile—kodwa ngenxa yesitoko esingaguquki. Sake salandelela ukuqhekeka okuphindelelayo kuzisekelo zephampu ze-ASTM A216 WCB ukuya ekuhlukaniseni i-manganese kumaqoqo e-billet athathwe ezigayweni ezintathu ezihlukene. Namuhla, konke ukuncibilika kuqala ngama-ingots ebanga elingu-1020–1045 aqinisekisiwe, aqinisekiswa nge-OES spectroscopy ngaphambi kokushaja. Okubi kakhulu, sihlanganisa ukulinganisa kokushisa ngamabha azo okuhlola afanayo—akukho ukuqagela “kokumela isampula”. Lokhu kuqinisekisa ukuziphatha kwesigaba esifanayo phakathi kwengxenye nombiko wayo wokuhlola wokusebenza. Ezingxenyeni ze-AMS 5387 ingxubevange ye-cobalt (evame ukuhlanganiswa kumahlanganisela ensimbi ye-carbon), sigcina ukulandeleka kwe-dual-melt: ibheshi eyodwa yomlomo we-cobalt, enye eyendlu yensimbi ye-carbon steel—kanye nemibhalo egcwele exhuma kokubili kulogu olufanayo lwesithando somlilo wokushisa ukushisa. Azikho izinqamuleli. Akukho ukuhlanganisa inqwaba.
Lapho Ukusakaza Kuphela Khona, Ukunemba Kuqala
Ukulingisa okuphelele akuqediwe ekunyakazeni. Iqedwa lapho indawo engu-0.002″ iqeda esihlalweni sevalvu yokucindezela idlula ukuhlolwa kokuvuza kwe-helium ku-10.−9 mbar·L/s. Lokho kudinga ukuhlanganiswa okuqondile—hhayi nje ukusakaza, kodwa ukwenziwa kwemishini ye-CNC, ukwelashwa kokushisa, kanye ne-metrology ngaphansi kophahla olulodwa. Isikhungo sethu se-ISO 9001 sisebenzisa i-5-axis milling kuma-post-annealed castings ukuze sibambe isikhundla sangempela ngaphakathi kuka-0.01 mm kumaphethini we-flange wemigodi engu-12. Sisebenza ngomshini izindawo zokugcina zokuvala *ngemuva* kokukhululeka kwengcindezi, hhayi ngaphambili—ukuqeda izindlela zokuvuza ezibangelwa yi-warpage. Ukuhlolwa kwe-CMM akulona isango lokugcina; ishumekwe phakathi nenqubo. Ngemuva komshini onzima, siqinisekisa ukugxila kwe-bore ebalulekile. Kungaleso sikhathi kuphela lapho siqhubeka nokuqeda ukusikeka. Lokhu kubamba ukuhlanekezela okushisayo kusenesikhathi—konga amahora angama-72 okumosha isikhathi sokuqeda indlu ngayinye enkulu.
Ukuqinisekiswa Komhlaba Wangempela, Hhayi Ukuthobela Amaphepha Kuphela
Amakhasimende ayabuza: “Ingabe uyakwazi ukuphatha amapulaki e-T800 cobalt alloy ashiselwe abe yizinqwaba zensimbi ye-carbon?” Yebo—kodwa kuphela ngenxa yokuthi siqinisekise inhlanganisela yensimbi engafani ngemijikelezo yokushisa engu-500 (-40°C kuya ku-+250°C) ngemephu yobuqotho bebhondi ye-ultrasonic. Bayabuza: “Ingabe amasilinda enu ayasinda ekugugulekeni kwamaphampu amanzi olwandle?” Yebo—ngoba siyawahlola ku-recirculating slurry rig yethu enokuqukethwe kwe-silica engu-12% ku-2800 RPM amahora angu-400, sikala ukulahleka kwezinto nge-laser profilometry. Ukuthola isitifiketi kubalulekile, kodwa ukuziphatha kwenkundla kubaluleke kakhulu. Kungakho konke ukuthunyelwa kuhlanganisa ukulandeleka okugcwele: inombolo encibilikayo, i-ID yomjikelezo wokuphatha ukushisa, i-serial yombiko we-CMM, nokuphuma komqhubi—hhayi nje isitifiketi sokuthobelana.
Ezingxenyeni zokusakazwa kwe-investimenti ye-carbon steel ebaluleke kakhulu, amandla awalinganiswa ngamathani noma isithombe esiyisikwele. Kukalwa ngama-microns wokubekezelelana okubanjiwe, amahora okulethwa kwesevisi, nokwehluleka kuvinjwe ngaphambi kokusebenza kokuqala. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge-a imboni ye-carbon steel investment casting parts lapho i-metallurgy ishayela imishini—futhi lapho konke ukubunjwa kuthwala isisindo sokusetshenziswa kwayo, hhayi nje ishidi lakho elicacisiwe.
