Xa iinjineli zichaza iinxalenye zokugalela iintsimbi zekhabhoni, abagcini nje uku-odola isinyithi-bafuna uzinzo lwe-dimensional phantsi kwe-350 bar hydraulic pressure, i-microstructural consistency kuwo wonke ama-500-unit batches, kunye nokunyaniseka komphezulu osinda ukuhamba kwe-slurry e-abrasive kwiiyure ze-12,000 zokusebenza. Elo nqanaba lokusebenza aliveli kwiziseko eziqhelekileyo. Ifuna a carbon steel utyalo-mali lokugalela iinxalenye umzi-mveliso yakhiwe malunga noqeqesho lwe-metallurgical-hayi nje amandla okuphosa.
Kutheni uTyalo-mali luphumelela kwiCarbon Steel Components
I-Sand casting ilawula imveliso ye-carbon steel ephezulu-kodwa iyasilela apho ubunzima bejometri budibana nobunzima obusebenzayo. Siye sabona izindlu ze-piston pump cylinder zikhatywa kabini: okokuqala ngo-0.18 mm ukuguquguquka kodonga kwi-valve port zone, emva koko kwi-micro-porosity kufuphi neendawo ezichaphazelekayo kubushushu emva kokunciphisa uxinzelelo. Utyalo mali lusonjululwe zombini. Inkqubo yayo ye-ceramic shell ihambisa i-± 0.05 mm ukunyamezela komgca kwiimpawu ezifana neeshaneli zokupholisa zangaphakathi kunye ne-concentric bearing bores-ngaphandle kwee-angles zedrafti okanye imigca yokuhlukana. Okubaluleke ngakumbi, ulawulo lokuqinisa umkhombandlela lunciphisa imingxunya ecuthekileyo kuguquko olutyebileyo ukuya-obhityileyo oluqhelekileyo kwimizimba yevalvu yoxinzelelo kunye ne-winch center shaft rollers. Urhwebo-off? Ixabiso eliphezulu ngenxalenye nganye. Imbuyekezo? Ukungasebenzi kwakhona kwi-GD&T-critical dataums. Kwizicelo apho ukungaphumeleli kuthetha ukuba ixesha lokuphumla lixabisa i-$ 18,000 / iyure, loo mathematika ayinakuxoxisana.
Ingqibelelo Yezinto Ezibonakalayo Iqala Phambi Kokugalela
Ukufakwa kwentsimbi yekhabhoni kuyasilela-kungekhona kwindlela engafanelekanga yokuphosa-kodwa kwisondlo esingaguqukiyo. Sakhe salandelela ukuqhekeka okuphindaphindiweyo kwisiseko sempompo ye-ASTM A216 WCB ukuya kulwahlulo lwe-manganese kwiibhetshi ze-billet ezithathwe kwii-mill ezintathu ezahlukeneyo. Namhlanje, yonke inyibilika iqala nge-1020-1045 yebakala le-ingots eqinisekisiweyo, engqinwe nge-OES spectroscopy ngaphambi kokutshaja. Okubaluleke kakhulu, sidibanisa ukutshisa ukushisa kunye nemivalo yovavanyo ehambelanayo-akukho "isampulu emele" ukucinga. Oku kuqinisekisa indlela yokutshintsha kwesigaba esifanayo phakathi kwenxalenye kunye nengxelo yovavanyo lomatshini. Kwi-AMS 5387 i-cobalt alloy alloy components (ehlala idityaniswe kwiindibano zentsimbi ye-carbon), sigcina ukulandelwa kwe-double-melt: enye ibhetshi ye-cobalt nozzle, enye i-carbon steel house-kunye namaxwebhu apheleleyo adibanisa zombini kwi-log yokushisa yokushisa okufanayo. Akukho ndlela zimfutshane. Akukho kudityaniswa kwebhetshi.
Apho ukuCasa kuphele khona, ukuchaneka kuyaqala
Ukuphosa okugqibeleleyo akugqitywanga xa kushukunyiswa. Igqitywe xa i-0.002 ″ yokugqiba umphezulu kwisitulo sevalve yoxinzelelo idlula uvavanyo lokuvuza kwe-helium nge-10.−9 mbar·L/s. Oko kufuna ukudityaniswa ngokuthe nkqo-hayi nje ukuphosa, kodwa umatshini we-CNC, unyango lobushushu, kunye ne-metrology phantsi kophahla olunye. Indawo yethu ye-ISO 9001 iqhuba i-5-axis milling kwi-post-annealed castings ukubamba indawo yokwenyani ngaphakathi kwe-0.01 mm kwiipateni ze-flange ezinemingxuma eli-12. Sisebenza ngomatshini iindawo zokutywina zokugqibela *emva* kwesiqabu soxinzelelo, hayi ngaphambili-ukuphelisa iindlela zokuvuza ezibangelwa yimfazwe. Ukuhlolwa kweCMM akulosango lokugqibela; ifakwe phakathi kwenkqubo. Emva komatshini ongqongqo, siqinisekisa ukugxila okubalulekileyo. Kuphela emva koko siye siqhubele phambili ukugqiba ukusikeka. Oku kubamba ukuphazamiseka kwe-thermal kwangoko-ukugcina iiyure ezingama-72 zokuchitha ixesha lokugqiba kwindlu nganye enkulu.
Ukuqinisekiswa Kwehlabathi Lokwenyani, Hayi Ukuthotyelwa Kwephepha Kuphela
Abathengi bayabuza: "Ngaba uyakwazi ukuphatha iiplagi ze-T800 cobalt alloy ezidityaniswe kwi-carbon manifolds yentsimbi?" Ewe-kodwa kuphela ngenxa yokuba siqinisekisile i-dissimilar-metal joint ngokusebenzisa i-500 ye-thermal cycles (-40 ° C ukuya ku-+250 ° C) kunye ne-ultrasonic bond integrity mapping. Babuza oku: “Ngaba izindlu zemibhobho yakho ziyasinda kukhukuliseko lwemibhobho yamanzi olwandle?” Ewe-kuba siyabavavanya kwi-recirculating slurry rig kunye ne-12% ye-silica content kwi-2800 RPM ngeeyure ze-400, ukulinganisa ukulahlekelwa kwezinto eziphathekayo nge-laser profilometry. Izatifikethi zibalulekile, kodwa ukuziphatha endle kubaluleke ngakumbi. Yiyo loo nto yonke into ethunyelwayo ibandakanya umkhondo opheleleyo: inombolo enyibilikayo, i-ID yomjikelo wokuphatha ukushisa, i-CMM yengxelo ye-serial, kunye nokusayinwa kwabaqhubi-kungekhona nje isatifikethi sokuthotyelwa.
Kwi-mission-critical carbon steel investment parts, ikhono alilinganiswa ngeetoni okanye umfanekiso osisikwere. Ilinganiselwa kwii-microns zonyamezelo ezibanjiweyo, iiyure zenkonzo ezinikezelweyo, kunye nokusilela kuthintelwe ngaphambi kokusebenza kokuqala. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge carbon steel utyalo-mali lokugalela iinxalenye umzi-mveliso apho i-metallurgy iqhuba umatshini-kwaye apho yonke into yokuphosa inobunzima bokusebenza kwayo, kungekuphela nje iphepha layo leenkcukacha.
