Lapho onjiniyela bayacacisa igobolondo lokubumba izingxenye zensimbi, abagcini ngoku-oda ukulingisa—bafuna ukuphindaphindeka kobukhulu phakathi kuka-±0.15 mm, ukungaguquguquki kwe-microstructure kuwo wonke amaqoqo angu-500+ kg, namandla aqinile abamba ngaphansi kwamabha angu-350 ashukumisayo kagesi. Ngakho-ke ukutholakala kweqiniso igobolondo ekubumbeni cast iron izingxenye ifektri ayimayelana nenani—imayelana nokuqondiswa kwe-metallurgical, ukusebenza obala kwenqubo, kanye nokungabekezeleli nhlobo ukuhlukahluka kwamanodule e-graphite.
Kungani Ukubumba Igobolondo Kuletha Lapho Ukusakazwa Kwesihlabathi Kwehla Kafushane
Sibone amaphrojekthi amaningi kakhulu ehluleka ngenxa yokuthi amaqembu acabange ukuthi "insimbi yensimbi" isho ukuthi "ishintshashintsha." Ayikwenzi. Ezindlini zamavalvu okucindezelayo noma amabhlogo wephampu ye-piston, i-graphite morphology ilawula ukuphila kokukhathala ngokuqondile. Ukubumba igobolondo kuletha izilinganiso zokupholisa ezilawulwayo—okubalulekile ohlotsheni A lwe-graphite ye-flake enokusabalalisa okufanayo. Ngokungafani nezinqubo zesihlabathi esiluhlaza, isikhunta segobolondo sisebenzisa i-phenolic resin-coated silica sand elashwe ku-230°C. Umphumela? Ukuqedwa kobuso u-Ra ≤ 6.3 µm, ama-engeli asalungiswa aphansi njengo-0.5°, nokulawula ukujiya kodonga kuze kufike ku-4.5 mm ngaphandle kokugudluzwa kwengqikithi. Sivamise ukubamba ama-callout e-GD&T afana nokubekezelela indawo Ø0.05 mm kuzimbobo zedowel ezingu-12-mm-ububanzi—ngaphandle komshini wesibili.
Ukuhlanganiswa Okuqondile Akuyona I-Buzzword-Ukunciphisa Ingozi Yakho
Abanye abahlinzeki banikeza ukuncibilika, ukwenza isikhunta, nokwenza imishini ukuze bahlukanise abathengisi. Lokho kudala amaphuzu amathathu okwehluleka ukulandeleka kokubalulekile, ama-handoff amathathu okukhukhuleka kobukhulu, kanye namathuba amathathu okungahambi kahle kokwelashwa. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ithimba elifanayo lengamele uchungechunge olugcwele: isitifiketi sempahla eluhlaza (ASTM A48 Class 35/45, EN-GJL-250), ukukhiqizwa kwesikhunta segobolondo, 1,480°C cupola + induction duplex melting, D10 MO00RIchining final CNC, CNC NMMchining ngokumelene ne-ASME Y14.5–2018. Lapho ikhasimende lase-Europe lidinga amayunithi angu-270 epulaki ye-cobalt-alloy ehambisana ne-AMS 5387, senze ukuhlaziywa kwencibilika kuwo wonke ama-ladle, amazinga we-O₂ orekhodwa emkhathini womlilo ngesikhathi sangempela, kanye nemephu yobulukhuni bemephu engxenyeni ngayinye—ngoba ukuchezuka kweqoqo elilodwa kusho amaviki angu-12 okungasebenzi emsebenzini.
Lapho Amakhathalogi Avamile Ephela—Izimfuneko Zakho Zangempela Ziqala
Amamaki ensimbi ajwayelekile awazixazululi izinkinga ezifana nokuguga kwama-winch center shaft roller noma ukuhamba ngebhayisikili okushisayo kusisekelo sephampu kawoyela negesi. Kungakho umsebenzi wethu uqala ngaphambi kwesikhunta: ukubuyekeza izindlela zakho zomthwalo osebenzayo, ukuhlonza ukugxila kwengcindezi ngokuqinisekisa kusengaphambili kwe-FEA, nokukhetha ama-alloys ayisisekelo afana nezimo zesevisi—hhayi izihloko zemininingwane yedatha. Ezimpahleni ezigqokwa kakhulu, sishintsha okulingana ne-carbon (CE) kuya ku-3.1–3.3 futhi sengeze u-0.25% Cu ukuze sicwengisise isikhala se-pearlite. Ezingxenyeni ezibalulekile zokudlidliza, sisebenzisa imijovo ene-Ba-Ca-Si ukucindezela ukwakheka kokugodola. Futhi yebo—sibhala zonke izinqumo kuphakheji ye-PPAP, okuhlanganisa imibiko yokuhlaziywa kwe-spectral namashadi kasayizi wokusanhlamvu nge-ASTM E112 ngayinye.
- Ama-valve okucindezela: Kwenziwe umshini kusukela ku-ASTM A278 Grade 65-45-12 i-ductile iron, ilashwe ngemva kokushisa yaya ku-220–240 HBW
- Izindlu zesilinda sephampu yePiston: I-EN-GJS-400-15 eyenziwe ngegobolondo enezibhobo zomshini ezigcinwe ku-ISO IT6
- Amawintshi emoto yobunjiniyela: I-T800 cobalt-based alloy castings enokulawulwa kokuqina kokuqondisa
- Imibhobho engajwayelekile: Ingxubevange ye-cobalt ye-AMS 5387, isixazululo-ifakwe ku-1,175°C ±5°C, bese icishwa ngamanzi
Buza Le mibuzo Emihlanu Ngaphambi Kokukhipha I-PO
Akuzona zonke izimboni zokubumba amagobolondo ezisebenza ngezinga elifanayo. Buza umphakeli wakho:
- Ungakwazi yini ukunikeza amashidi elogi ancibilikayo abonisa izinga lokushisa leladle, ukwakheka kwe-slag, kanye nesikhathi sokugoma kumaqoqo amathathu okugcina?
- Ingakanani isisindo sakho esiphezulu sesiqephu esisodwa—futhi ubuqinisekisa kanjani ubuqotho besikhunta ezigabeni ezinogqinsi olungaphezu kuka-120 mm?
- Ingabe wenza ukuhlolwa kwe-ultrasonic kukho konke ukulingisa >50 kg, nge-ASTM E186 ngayinye?
- Ukuqinisekisa kanjani ukuhlobana kokuqina kobuso phakathi kwe-Brinell ne-Rockwell ezingxenyeni eziphethwe ukushisa?
- Ingabe i-ISO 9001:2015 yesitifiketi sakho siqondene ngqo nokubumba igobolondo nokwenza umshini onembile—noma “ukukhiqiza okuvamile”?
Uma izimpendulo zingacacile noma zibambezelekile, hamba. Ukulingisa okunembayo kudinga ukuziphendulela okunembayo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge-a igobolondo ekubumbeni cast iron izingxenye ifektri lapho ama-metallurgists abuyekeza khona imidwebo ehambisana nochwepheshe bemishini—futhi lapho wonke umjikelezo wokuphatha ukushisa ufakiwe, uphenyo ngalunye lwe-CMM lulinganiswa nsuku zonke, futhi konke okuthunyelwayo kuhlanganisa ukulandeleka okuphelele kwempahla kuze kufike enambeni ye-ingot. Asithumeli izingxenye. Sithumela izimvilophu zokusebenza eziqinisekisiwe. Kuzinhlelo ezisebenza ngogesi eziphusha ibha engu-400, kumaphampu aphesheya kwezilwandle asebenza amahora angu-20,000 ngaphandle kokulungiswa kabusha, ezimotweni zobunjiniyela ezisebenza -40°C izimo ze-Arctic—umehluko awukho eshidini le-specpe. Kukumaqhuqhuva, imingcele yokusanhlamvu, kanye nezinqumo ezibhaliwe ezenziwe ngaphambi kokuthululwa kokuqala.
