Xa iinjineli zichaza 304L intsimbi engenasici kwi-corrosion-resistant fabrication, abakhethi nje ibakala-bazimisele ukuthembeka ixesha elide kwiindawo ezinobundlobongela. Siye sabona abathengi besala iindawo ezinomda ngokugqibeleleyo ngenxa yokungangqinelani kwe-microstructural kukhokelela ekufakweni kwangaphambi kwexesha emanzini olwandle apholiseke kwii-hydraulic manifolds. Abanye bavuma ukuhanjiswa kuphela ukuze bafumanise ukubola kwe-weld emva kweenyanga ezintandathu zokuvezwa okwethutyana kumanzi enkqubo eklorinithiweyo. Ezi ntsilelo azibanga ngenxa yoyilo olulambathayo-zisuka kwizikhewu phakathi kokucaciswa kwezinto eziphathekayo kunye nokubulawa kwesinyithi emhlabeni. Yiyo loo nto ukukhangela kwi-a I-304L yefektri yensimbi engenasici ngolawulo lwenkqubo ebhaliweyo-hayi nje izatifikethi zokusila-ayixoxiswana.
Ukuxhathisa kwe-corrosion yokwenyani kwi-304L kuxhomekeke kwizinto ezintathu ezidityaniswe ngokuqinileyo: umxholo wekhabhoni esezantsi kakhulu (<0.03% max), ibhalansi ye-chromium-nickel engaguqukiyo (18-20% Cr, 8-12% Ni), kunye nokungabikho kwesigaba se-sigma okanye imvula ye-carbide kwiindawo ezichaphazelekayo kubushushu. Ababoneleli abaninzi badibana ne-ASTM A240 ephepheni kodwa bayasilela ngexesha lokuwelda okanye ukugoba. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke indawo ye-304L ifumana ukuqinisekiswa okuphindwe kabini-okuqinisekisiweyo kokulandelelwa kwemathiriyeli ekrwada *plus* kuhlalutyo lwe-spectrographic yangaphakathi endlwini phambi kokuba kuqale ukuphosa okanye ukwenziwa komatshini. Silinganise ukuya kuthi ga kwi-15% yokwahluka kwi-intergranular corrosion resistance kwiibhetshi ukusuka kwii-mill ezingaqinisekanga-nangona zonke iikhemikhali ezixeliweyo ziwela ngaphakathi kwe-spec. Umehluko? Ulawulo lwembali ye-Thermal ngexesha lokuqengqeleka okushushu kunye nokufakwa kwe-annealing. Indawo yethu igcina iiprofayili ezingqongqo zesithando somlilo kwaye ipholisa i-304L phantsi kweengubo zerhasi engasebenziyo ukucinezela uvakalelo.
Ukusebenza kokubola kuyawohloka xa uyilo luzisa izinto eziguquguqukayo ebezingalindelekanga. Qwalasela izindlu zempompo ze-oyile kunye nenkonzo yerhasi engaselunxwemeni: zifuna unyamezelo oluluqilima, iiwelds eziqinileyo, kunye nokugqiba komphezulu ongaphantsi kweRa 0.8 µm. Iivenkile eziqhelekileyo ze-CNC zihlala zigawula i-passive oxide layer ngexesha lokugqiba-ebonisa ukufakwa kwentsimbi engaphantsi komhlaba eziba ziindawo zokuqalisa i-galvanic. Sidibanisa i-passivation *ngoko nangoko emva komatshini wokugqibela, sisebenzisa iibhafu ze-citric acid eziqinisekisiweyo nge-ASTM A967 nganye. Akukho asidi nitric. Akukho ukuhlamba ngokukhawuleza. Inxalenye nganye ifumana ixesha lokuhlala lilinganiswe kubunzima bayo kunye nejometri. Silandele ukusilela kwibala apho abakhuphisana nabo basebenzise iibhiliti ze-304L ezifanayo kodwa batsiba i-electropolishing yangemva komatshini-okukhokelela kwi-3× ekhawulezayo ukubola kwi-crevice emoyeni ogcwele i-brine.
Ukudityaniswa ngokuthe nkqo kwahlula ababoneleli abathembekileyo kwabo bathengiselwayo. A I-304L yefektri yensimbi engenasici ukuba ipleyiti yokusika kuphela ayinakuqinisekisa uzinzo lwe-dimensional ngokusebenzisa ibhayisekile eshushu. Kodwa xa ukuphosa, ukwenziwa, kunye nokugqiba kwenzeka phantsi kophahla olunye-kunye nedatha ye-CMM ekwabelwanayo ngayo, iilogi ezidityanisiweyo zonyango lobushushu, kunye nokutolika okudibeneyo kwe-GD&T-umngcipheko uyahla. Siphosa amaqokobhe otyalo-mali angama-304L kwimizimba yevalvu entsonkothileyo, emva koko umatshini wokutywina iindawo ezibalulekileyo zokutywina ngendlela enye ukuze ubambe ±0.01 mm ngokwenyani. Akukho handoffs. Akukho ukulungiswa kwakhona. Akukho ngqikelelo malunga nokuba ukwanda kwe-thermal ngexesha lokuphosa kuchaphazela njani ukulungelelaniswa kokugqibela. Oku akuyothiyori. Omnye umxhasi waseYurophu watshintshela kuthi emva kwemizamo emibini engaphumelelanga kunye nabathengisi abahlukeneyo be-Foundry / machine shop-bobabini baphoswa ukunyamezela okufanayo kwe-0.025 mm kwi-high-pressure piston housing. Siyibambe kuhlolo lwenqaku lokuqala sisebenzisa ukuqinisekiswa kwelaser tracker ngokuchasene neCAD yegama.
Abathengi behlabathi babuza imibuzo emithathu ngaphambi kokuba bazibophelele: Ngaba unokungqina ukuhambelana kwiindawo ezingama-500+? Ngaba ungayiphinda kunyaka ozayo? Ngaba ungayibhala kubaphicothi-zincwadi bethu? QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iimpendulo ewe-ngokulandelelanisa ibhetshi epheleleyo, iirekhodi ezihambelana ne-ISO, kunye nokuhanjiswa kwe-zero-defect kwi-92% ye-odolo ephindaphindiweyo kwiinyanga ezingama-36 ezidlulileyo. Asiyiphathi i-304L njengempahla yorhwebo. Siyiphatha njengenkqubo esebenzayo: i-chemistry + microstructure + surface state + dimensional fidelity. Ukuba isicelo sakho sifuna ukuchasana nokuqhekeka koxinzelelo lwekloridi, i-acidic condensates, okanye ukulayishwa kwebhayikile ye-thermal, qala ngemathiriyeli eqinisekisiweyo kwinkonzo yokwenyani-hayi nje iingxelo zelebhu. Ndwendwela https://www.tsingtaocnc.com ukuphonononga iphothifoliyo yethu yesiqinisekiso se-304L, ukucela iingxelo zovavanyo lwemathiriyeli kwiqashiso elisebenzayo, okanye ucwangcise uphononongo oludibeneyo lwe-GD&T kumzobo wakho olandelayo wokwenziwa.
