Ubona i-316 kunye ne-316L yentsimbi engatyiwayo icacisiwe ngalo lonke ixesha, kodwa umahluko wokwenyani ayiyonobumba nje ekwidatha yedatha. Kukwii-welds, kwimingxuma yomhlwa, kunye namalungu abuya endle. Abaninzi bacinga ukuba bayatshintsheka. Azikho, kwaye ndiyibonile ingqikelelo ebiza kakhulu.
Umxholo weCarbon: Ayilonani nje
Umahluko ophambili yikhabhoni. I-316 inobuninzi be-0.08%, ngelixa 316L intsimbi engenasici ifikelele kwi-0.03%. Ivakala ingenamsebenzi, akunjalo? Kwithiyori, mhlawumbi. Kodwa ekusebenzeni, loo carbon ifuna ukudibanisa nechromium ngexesha le-welding, yenze i-chromium carbides kanye kwimida yengqolowa. Olu lwazi luba ichromium enika intsimbi ukuxhathisa umhlwa, ishiya indlela esengozini ecaleni kwendawo echatshazelwe bubushushu. Kwinxalenye ehleli nje, mhlawumbi kulungile. Nantoni na ejongene neekloridi okanye iiasidi, yindawo yokusilela efakwe ngaphambili.
Ndikhumbula ibhetshi yemizimba yevalvu kumxhasi wokulungisa imichiza. Ushicilelo lwathi 316 alunabala. Ivenkile, izama ukugcina iirandi ezimbalwa ngekhilogram, yasebenzisa isitokhwe sebha ye-316 eqhelekileyo. Amalungu ayenziwe ngoomatshini kakuhle, adlula kuhlolo lokuqala. Kodwa kwiinyanga ezintandathu emva koko, safumana imifanekiso: iintanda ezintle, ezifana ne-spider-web-ephuma kumthungo ngamnye we weld. Umhlwa phakathi kwegranular. Umthengi waye, ngokuqondakalayo, enomsindo. Kulapho ufunda ukubuza, ngoko nangoko: Ngaba oku kuya kuthungelwa? Ithini indawo yenkonzo? Ukuba impendulo nguewe kwi-welding, utyhala kwibakala lika-L. Akukho ngxoxo.
Yiloo nto umniki-mpahla elandelekayo kubalulekile. Inkampani efana QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. (QSY), kunye neminyaka engamashumi amathathu ekukhupheni kunye nokusebenza, baya kufumana oku. Xa usenza utyalo mali okanye CNC Machining amacandelo aya kuba yinxalenye yendibano enkulu edityanisiweyo, ukuqala ngenqanaba lekhabhoni ephantsi ayikhethi-lukhetho kuphela olunengqondo. Amava abo ngealloyi ezikhethekileyo athetha ukuba bazibonele ngokwabo iziphumo zokungahambi kakuhle kwemathiriyeli.
UkuSebenza kunye nokuQiniseka: Inyani yoMgangatho wevenkile
Makhe sithethe ngokusika kunye nokubumba. Ayililo i-316 okanye i-316L iphupha likamachini-bangama-gummy, basebenza nzima njengokuphambana ukuba awulumkanga. Kodwa phakathi kwezi zimbini, ndinganika umda omncinci ukuya kwi-316L yokuzinza komatshini kwiindawo ezinzima. Ikhabhoni esezantsi ibonakala ikhokelela kwikhefu le-chip elingaguquguqukiyo ngakumbi, ukuthambekela okuncinci kokwakhiwa komphetho kwisixhobo, ngakumbi kwimisebenzi eqhubekayo efana nokujika iiprofayili zeempompo zeempompo.
Ukwenza okanye ukwenza, i-316L ixolela kakhulu. Amandla ayo esivuno esisezantsi kunye nokudumba okuphezulu ekuqaleni kwenza kube lula ukutyhala kwinto entsonkothileyo iqokobhe ngundo ukuphosa iipateni ngaphandle kwemiba yokuqala. Kwake kwafuneka ukuba nzulu-zoba iikomityi ezinodonga olucekethekileyo ukusuka kwi-316 sheet. Ukubaleka kokuqala ngomgangatho we-316 kukhokelele kwireyithi ye-scrap engama-30% ukusuka kwiintanda ezincinci kwiradiyasi ezotyiweyo. Tshintshela kwi-316L, kwaye umcimbi waphela nya. Izinto eziphathekayo zihamba ngcono.
Le yeyona ngongoma ibalulekileyo kubavelisi. Ukuba ukhangela iicastings ezenziwe kwangaphambili okanye izikhewu ezinoomatshini, ukucacisa ibakala elichanekileyo lenkqubo yokuvelisa sisiqingatha sedabi. Iqabane eliyiqondayo inkqubo, njengale nto ungayifumana kuyo tsngtaocnc.com, asikokuthengisa nje intsimbi; basebenzise ezabo CNC Machining kunye nolwazi lokuphosa ukukhetha ibakala eliya kuziphatha ngokuqikelelwayo phantsi kwezixhobo zabo kunye nokungunda, ukusindisa wonke umntu intloko ebuhlungu phantsi komgca.
Intsomi yokuRhwalala kunye neNyaniso yeMolybdenum
Intsomi eqhelekileyo kukuba i-316L ixhathisa i-corrosion ngaphezu kwe-316. Akunjalo. Ukuxhathisa isiseko sabo, okubonelelwa yi-2-3% ye-molybdenum kunye ne-chromium-nickel matrix, iyafana ne-annealed, i-non-welded state. I-molybdenum ngundoqo-yinto egquba ukuxhathisa kwi-pitting kunye ne-crevice corrosion kwindawo ye-chloride ngaphezu kwe-304. I-advantage ye-L ye-grade kuphela ekugcineni ukuxhathisa okungokwemvelo emva kwemijikelo ye-thermal efana ne-welding.
Kodwa nantsi i-nuance: kwi-acids oxidizing kakhulu (njenge-nitric), ibali liyakwazi ukujika. Kukho idatha ethile kunye nobungqina be-anecdotal obuvela kwizandla ezindala ukuba umgangatho we-316 ngamanye amaxesha unokwenza ngcono kancinci kwezi ndawo zikhethekileyo, ezingekho chloride. Into malunga nozinzo lwefilimu yokwenziwa. Andibhejanga iprojekthi kuyo, kodwa sisikhumbuzo sokuba isayensi yezinto kunqabile ukuba ibe yinto epheleleyo. Kufuneka wazi utshaba oluchanekileyo olujongene nalo.
Ukusetyenziswa kolwandle, iikhemikhali, okanye ukwenziwa kokutya okusemgangathweni-apho i-chlorides, i-organic acids, okanye izisombululo zokubulala iintsholongwane zikhona-ubukhulu obudityanisiweyo be-welded. 316L intsimbi engenasici iyenza ibe yinto emiselweyo. Lukhetho olukhuselekileyo, oluguquguqukayo lwezixhobo ezenziweyo. Xa ndijonga ipotifoliyo yezinto zengcali efana ne-QSY, ebandakanya ezi ntsimbi kunye ne-nickel-based alloys kwimisebenzi enzima ngakumbi, ibonisa ukuba baqhele ukujongana nezi nkcukacha zincinci, eziqhutywa kusetyenziswa, hayi nje ukuhambisa isitokhwe sentsimbi yegeneric.
Iindleko kunye neSibonelelo: IKhalculum eSebenzayo
Ewe, i-316L ihlala iphethe iprimiyamu encinci. Kodwa olo hlalutyo lweendleko alunamsebenzi ukuba luyekwa kwi-invoyisi yempahla ekrwada. Kuya kufuneka ujongane neendleko ezipheleleyo zokwenziwa kunye nomjikelo wobomi. Ukuba usebenzisa umgangatho wama-316 kuthetha ukuba kufuneka ukhuphe i-welds ukunyibilikisa i-carbides (inyathelo elongezelelweyo, elixabisa kakhulu, nelihlala ligqwethekile), okanye ubeka umngcipheko wokusilela, izibalo ziyatshintsha ngoko nangoko. Umgangatho we-L uhlala ususa loo mfuno yonyango lobushushu emva kwe-weld.
Ukufumana enye into. Nge-global push for standardized, weldable structural stainless, i-316L idla ngokufumaneka ngokulula kuluhlu olubanzi lweefom-ipleyiti, umbhobho, ukufakwa, ukuchithwa-kunomgangatho we-316. Ukuzama ukufumana ubungakanani obuthile kwi-real 316 bar stock for machining job ngamanye amaxesha kunokuthatha iiveki ezinde ngaphezu kokufumana iqabane layo le-316L.
Oku kufumaneka kuzondla kumakhonkco onikezelo athembekileyo kubavelisi. Ukusebenza ixesha elide, njengeQingdao Qiangsenyuan Technology Co., Ltd., egxininisa izinto ezifana intsimbi engenasici kunye neealloyi ezikhethekileyo, mhlawumbi ziseke amajelo amabakala afanelekileyo. Imbali yabo yeminyaka engama-30 ibonisa ukuba bakhe ubudlelwane bokufumana hayi isinyithi kuphela, kodwa isinyithi esichanekileyo somsebenzi, odla ngokuba ngumsebenzi onzima.
Isigwebo seSicelo: Ukusetyenziswa Nini
Ngoko, umgaqo olula wesithupha: ukuba uya kuthungwa kwaye ujongene nenkonzo enobungozi, sebenzisa 316L intsimbi engenasici. Isingxi. Oku kubandakanya i-90% yezicelo zemizi-mveliso-iinkqubo zemibhobho, iinqanawa zoxinzelelo, oomatshini bokulungisa ukutya, izixhobo zaselwandle, iitanki zamayeza. Ukuzithemba okongeziweyo kuxabisa umahluko weendleko ezincinci.
Ungawuqwalasela nini umgangatho 316? Kumalungu angenawo i-welded, okanye izicelo apho amandla obushushu obuphezulu (ngaphezu kwe-800 ° F) yinkxalabo ephambili, njengoko i-carbon ephezulu kancinci inokunika amandla angcono okurhubuluza. Cinga ngamalungu athile eziko, iishafti ezingadityaniswanga, okanye iziqhoboshi ezithile. Kodwa nangona kunjalo, uthengisa ngenzuzo enobushushu obuphezulu ukuze ufumane isohlwayo esiqinisekisiweyo se-weldability. Lukhetho lwe-niche.
Ekugqibeleni, yehla kwingcaciso enolwazi. Asikokuba ibakala elinye lingcono, kodwa malunga nokuba elinye lifaneleke ngakumbi. Injongo kukutshatisa iipropati zendalo zemathiriyeli kwinkqubo yokuvelisa kunye nokusetyenziswa kakubi kokugqibela. Olo luhlobo lwesigwebo esisebenzayo esahlula umthengisi wamacandelo kwiqabane lokwenyani lemveliso. Ngumahluko phakathi kokwenza imilo kunye nokuhambisa icandelo elenzayo, nelihlala lihleli, kwihlabathi lenene.
