Xa iinjineli zichaza isanti ephosa intsimbi engatyiwayo kwi-high-pressure valves hydraulic valves okanye izindlu zempompo ze-offshore, abakhethi nje inkqubo-babheja ngokuzinza kwe-dimensional, ukumelana nokubola, kunye nokunyaniseka kwe-microstructural phantsi koxinzelelo lwehlabathi lokwenene. Ababoneleli abaninzi bathembisa ukuphoswa okuchanekileyo. Abambalwa bahambisa i-AMS 5387 i-cobalt i-alloy nozzles ehambelanayo * kunye * kunye ne-tight-tolerance 316 i-winch shafts yensimbi engenasici ukusuka kumgca ofanayo wokuvelisa-ngaphandle kwe-batch-to-batch drift kwisakhiwo sengqolowa okanye ubunzima bomhlaba. Oko kuhambelana kuqala ngokulandeleka kwezinto, kungekhona amabango okuthengisa.
I-Sand Casting Stainless Steel: Apho i-Metallurgy idibana noMsebenzi-obalulekileyo
I-Sand casting steel stainless ayiphelelwa lixesha-ikhethwe ngobuchule xa iinxalenye zidlula i-15 kg, zineepaseji ezintsonkothileyo zangaphakathi, okanye zifuna unyango lobushushu phambi komatshini wokugqibela. Ngokungafaniyo nokuphosa utyalo-mali, ukugaywa kwesanti kubamba amacandelo amakhulu angenaziphene ngaphandle kweziphene zeqokobhe leceramic okanye ukungcoliseka kwe-silica eshiyekileyo. Kodwa impumelelo ixhomekeke kwizinto ezintathu ezingaxoxiswanayo: ukufunwa kwemathiriyeli ekrwada eqinisekisiweyo (kungekhona nje iziqinisekiso zelitye lokusila, kodwa iingxelo ze-spectrographic ezithile), ulawulo lokufuma kwesanti yokungunda ngaphakathi kwe ± 0.3%, kunye namazinga okupholisa alawulwayo ukuphepha ukubunjwa kwesigaba se-sigma kumabanga aphindwe kabini.
Siye sabona abathengi besala zonke ii-CF8M castings ngenxa yokuba i-porosity eyanciphayo yenziwa kufutshane neendawo zokungena-ngaphandle kovavanyo lwe-ultrasonic. Oyena nobangela? Uxinzelelo lwe-ramming olungahambelaniyo kuzo zonke izitishi zokubumba ngesandla. Kwiziko lethu le-Qingdao, ukulungiswa kwesanti ezenzekelayo kunye nexesha lokwenyani lokujonga ubushushu bebhokisi kuphelisa oko kuguquguquka. Yonke i-stainless steel stainless ithululela i-molds yangaphambili kwi-120-150 ° C, ukunciphisa ukutshitshiswa kwe-thermal kunye nokuphucula ukugqitywa kwendawo ukuya kwi-Ra 6.3 μm njenge-cast-ixesha lokusika i-post-machining nge-22% ngokomyinge.
Kutheni uHlanganiso oluthe nkqo lubetha ababoneleli “abaphosa kuphela”
Ezinye iifektri zenza iintsimbi ezingenasici. Abanye ngomatshini kubo. Bambalwa abenza zombini-kwaye bambalwa basalawula unyango lobushushu kunye nokugqiba endlini. Xa indlu yakho yepiston yepompo yesilinda ifuna izixhobo zentsimbi ze-H13 ezifakwe kwi-brazed emzimbeni we-CF3M, emva koko lukhuni ukuya kwi-48-52 HRC * emva komatshini wokutywina iindawo ezibalulekileyo, i-handoffs phakathi kwabathengisi bazisa iimpazamo zokulungelelanisa, ukuphazamiseka kwesikali se-oxidation, kunye nembali yokushisa engafumanekiyo.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., elinye iqela lilawula ulandelelwano olupheleleyo: uyilo lwepateni → ukubumba kwesanti eluhlaza → ukugalelwa kwesithando somlilo → ukuthomalalisa isiqabu soxinzelelo → ukujika kwe-CNC/ukusila → uqinisekiso lweCMM → ukugqitha. Sihambise iziseko zempompo ze-316L apho ubukhulu bodonga buhluke ngaphantsi kwe-± 0.15 mm kwi-1.2-meter spans-ifumaneka kuphela ngenxa yokuba i-metrologist efanayo iqinisekisa imilinganiselo ngaphambi nangemva kokunyanga kobushushu usebenzisa i-CMM probe efanayo.
- Uzinzo lweDimensional: ≤0.05 mm ukutenxa kwiimpawu ezingaphezulu kwe-300 mm ubude
- Ulawulo lweMicrostructure: ASTM A957 Level 2 dendrite spacing iqinisekisiwe ngebhetshi nganye
- Umphezulu wengqibelelo: Akukho zintanda zangaphantsi komhlaba zifunyenwe ngokuhlolwa kwe-fluorescent penetrant (FPI) kwi-10× yokukhulisa
Intsebenzo yeHlabathi yokwenyani: Ngaphaya kwePhepha eliKhethekileyo
"Intsimbi engenasici" ayithethi nto ngaphandle komxholo. I-304 yokuphosa inokusinda kwinkonzo yamanzi ahlaziyekileyo-kodwa ingaphumeleli ngentlekele kwiindawo zerhasi emuncu ngenxa ye-chloride-induced pitting. Yiyo loo nto sivavanya lonke ubushushu bentsimbi engenastainless kwiimeko zokwenyani zesicelo: ukutshizwa ngetyuwa kwibhayisekile yewinch rollers, thermal cycling ukusuka ku -40°C ukuya +200°C kubuninzi behydraulic manifolds, kunye nokulinganisa okukhawulezileyo kokutya kweoli kunye nemizimba yevalvu yegesi.
Kunyaka ophelileyo, umxhasi waseYurophu wayefuna iirola zeshaft ezitshintshwayo kwiifestile zemoto yobunjineli ezisebenza kwiimeko zentlango. Umthengisi wabo wangaphambili wasebenzisa i-G-X6CrNi18-10 eqhelekileyo kunye ne-220 HB ubunzima-ubomi be-roller obuphakathi kweeyure ze-470. Siye satshintshela kwi-custom-sand-cast-cast 1.4408 (CF3M) kunye nesisombululo se-annealing kwi-1050 ° C + ukucinywa kwamanzi ngokukhawuleza, ukufezekisa i-285 HB kunye ne-32 J yempembelelo yokuqina kwi -20 ° C. Idatha yasendle ibonisa iiyure eziyi-1,850+ zithetha ixesha phakathi kokusilela. Umahluko wawungekho nje ibakala lezinto eziphathekayo-lalilawulwa izinga lokuqiniswa kunye nokusabalalisa kwe-carbide.
Ukukhetha iFactory yakho yeNtsimbi eNyenziwe ngeSanti: Imibuzo emithathu eDiza iNyaniso
Ngaphambi kokusayina i-NDA, buza:
- "Ndibonise iingxelo zakho ezintathu zokugqibela ze-316L ze-heat's spectrographic-kunye neziphumo zovavanyo oluhambelanayo." Ukuba bayathandabuza, ukuqinisekiswa kwezinto zabo kusekelwe ephepheni, kungekhona inkqubo-edibeneyo.
- "Ukuthintela njani ukucholwa kwekhabhoni ngexesha lokugalela?" Iileyile ezingacocekanga okanye ixesha lokuhlala eligqithileyo li-oxidize ichromium. Sisebenzisa ivacuum degassing kunye nezongezo zetitanium ukutshixa ikhabhoni ngaphantsi kwe-0.03%.
- "Yeyiphi eyona nto ide iqhubela phambili kwimidlalo yeqonga efanayo ngaphandle kwesiqinisekiso?" Impendulo yethu: Iibhetshi ezingama-47 ze-AMS 5387 i-cobalt alloy pump parts-abasebenzi abafanayo be-Foundry, inkqubo yesanti efanayo, ukulinganisa kwesithando somlilo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwi-santi casting steel stainless factory eyakhelwe ukusebenza okuphindaphindiweyo-hayi iprototypes enye. Asithengisi iicastings. Sihambisa isiqinisekiso esisebenzayo: iivalve zoxinzelelo ezitywina kwi-bar ye-350, izindlu zempompo ezixhathisa ukuguguleka kwe-cavitation kwiiyure ze-12,000 +, ii-winch shafts ezigcina ukuqina kwe-torsional emva komjikelezo we-50,000 womthwalo. Yiloo nto eyenzekayo xa i-metallurgy, machining, kunye nolawulo lomgangatho lukwabelana ngesicwangciso somgangatho omnye-kunye nekhonkco lokuphendula.
