Xa iinjineli zichaza I-Sanicro28 yentsimbi engenasici kumatshini, abakhethi nje enye i-alloy-bakhetha izinto ezenziwe ngobunjineli ukuze baphile kwi-chloride enobudlova, i-asidi, kunye neendawo zokushisa eziphezulu. Kodwa ukukhangela okuthembekileyo I-Sanicro28 yensimbi engenasici kwifektri yomatshini amaqabane ahlala engumceli mngeni othe gqolo. Ababoneleli abaninzi kakhulu bathembisa ukuhambelana-ke bazise ubume obungahambelaniyo benkozo, ukugqiba komphezulu osecaleni, okanye ukukhukuliseka okulinganayo emva konyango lobushushu. Sizibonele mathupha: indlu yempompo ye-hydraulic yaqhekeka kwi-bar ye-42 ngenxa yokuba umthengisi weqa ukuqinisekiswa kwe-annealing; ivalve yesitofu samanzi olwandle ayiphumelelanga kuvavanyo lwe-corrosion emva kweenyanga ezintandathu-kungekhona ngenxa ye-chemistry ye-Sanicro28, kodwa ngenxa yokuba ukuphosa akuzange kuphathwe isisombululo * kwaye * ifakwe kwi-ASTM A967 Class VI.
Kutheni i-Sanicro28 ifuna ngaPhantsi koMgangatho weNsimbi eNgatyiwayo
I-Sanicro28 (UNS N08028) ayisiyo "intsimbi nje engenasici ene-nickel eyongezelelweyo." I-chromium yayo ye-27%, i-31% ye-nickel, i-3.5% ye-molybdenum, kunye nomxholo we-nitrogen olawulwayo uhambisa ukuchasana okukhethekileyo kwi-pitting, i-crevice corrosion, kunye noxinzelelo lwe-corrosion cracking-kodwa kuphela xa ingqibelelo ye-metallurgical igcinwa kwisinyathelo ngasinye. Oko kuthetha ukuba akukho ndlela zimfutshane ekulandeleleni izinto ezikrwada, akukho kuthomalalisa kwisisombululo solawulo lweqondo lobushushu (1120-1180 ° C), kunye nonyamezelo lwe-zero kwi-intergranular sensitization ngexesha le-welding okanye i-machining igalelo lobushushu. Uninzi lweevenkile ezisemgangathweni zentsimbi engenasiphene azinalulinganiso lweziko, ukubeka iliso kwi-atmosphere, okanye iiprothokholi zokudlula emva komatshini ezifunekayo. Bayenza ngomatshini-kodwa abayenzi *inkosi* yayo.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siyiphatha i-Sanicro28 njengenkqubo esebenzayo-kungekhona nje into ebonakalayo. Ibhetshi nganye ifika neengxelo ezipheleleyo zovavanyo lokusila (MTRs) eziqinisekisa ukuthotyelwa kwe-ASTM B673. Imivalo engenayo ingena kwi-spark spectrometry kunye nokuqinisekiswa kwe-PMI ngaphambi kokusika. Ngexesha le-CNC yokuguqula imizimba yevalve yoxinzelelo, sinciphisa i-spindle RPM kunye nesantya sokutya ukubamba ubushushu besixhobo esingaphantsi kwe-300 ° C-ukuthintela iileya ezinobunzima bokusebenza ezibamba i-chlorides. Emva komatshini, iinxalenye ziya ngqo kwiziko elihlanjululwe ngenitrogen ukuze kufakwe isisombululo esipheleleyo, kulandele ukucinywa kwamanzi okukhawulezayo okuqinisekiswe yimephu ye-thermocouple. Akukho kupholisa umoya. Akukho kuxutywa kweebhetshi. Akukho ngqikelelo.
Udibaniso oluthe nkqo luSombulula i-Sanicro28 Consistency Gap
Iifektri ezininzi zikhuphela ngaphandle, ukwenziwa komatshini, okanye ukugqiba-ukudala amanqaku e-handoff apho ukusebenza kweSanicro28 kwehla. I-Foundry inokugalela ngokuchanekileyo, kodwa ukuba i-machinist ayilungelelanisi i-Sanicro28's 40% ye-conductivity ephantsi ye-thermal xa ithelekiswa ne-316 engenasici, isixhobo sokuphambuka sichitha i-callouts ye-GD & T. Ukuba i-heat treatmenter isebenzisa umoya ongeyena-inert, i-chromium carbides idlula kwimida yengqolowa-ibulala ukuxhathisa ukubola.
Siyaziphelisa ezo zithuba. Indawo yethu ehambelana ne-ISO iphatha yonke into yangaphakathi: utyalo-mali lwezindlu ze-cylinder eziyinkimbinkimbi, i-multi-axis CNC machining ye-piston pump flanges ene-± 0.01 mm yokunyamezela indawo, kunye nokugqitywa kwe-electropolished surface ukuya kwi-Ra ≤ 0.4 µm. Kwi-Sanicro28 winch center shaft rollers, siphosa iimilo ezikufutshane-netha, emva koko senze i-annealing yokunciphisa uxinzelelo ngaphambi kokuba ujike nzima-ukuqinisekisa ukuzinza kwe-microstructural phantsi komthwalo we-cyclic torsional. Inxalenye nganye iphethe umkhondo wezinto ezipheleleyo: inombolo yeloti, i-MTR ID, ilog yonyango lobushushu, ingxelo yeCMM, kunye nesatifikethi soburhabaxa bomphezulu.
- I-Sanicro28 i-valve yoxinzelelo - ifakwe kwi-billet eyenziwe, i-ASME B16.34 ilinganiswe, i-hydrotested ukuya kwi-1.5× MAWP
- Iziseko zempompo - i-santi-cast kunye ne-lugs edibeneyo yokukhwela, ukukhulula uxinzelelo, kunye nomhlaba-umhlaba ukuya kwi-flatness ≤ 0.05 mm / m
- Amalungu oomatshini angekho mgangathweni we-Sanicro28 - eyilwe ngempendulo ye-DFM, kubandakanya ukwenziwa kodonga olutyebileyo ukunqanda ukukrazuka okushushu ekujuleni
Ukuqinisekiswa Kwehlabathi Lokwenyani, Hayi Ukuthotyelwa Kwephepha Kuphela
Abathengi bayabuza: "Ngaba ungadibana ne-NACE MR0175/ISO 15156 ngenkonzo emuncu?" Ewe-kodwa kuphela emva kokuqinisekisa ukuveliswa kwemveliso nganye kwi-ASTM G48 Indlela A (i-ferric chloride pitting test) kunye ne-ASTM G123 (uvavanyo lwe-corrosion test). Asixhomekeke kwiicerti ze-alloy generic. Sivavanya *inxalenye yakho, *kwijiyometri* yakho, sisebenzisa *indawo yenkonzo ojolise kuyo*. Omnye umntu osebenza kuLwandle lwaseMntla wayefuna ukuntywiliselwa iiyure ezili-1,000 kumanzi olwandle enziweyo akwi-80°C. Sihambise iisampulu ezintathu zokufaneleka-nganye ivavanywe ngokuzimeleyo, kunye ne-metallography yecandelo elinqamlezayo eliqinisekisa ukuba akukho sigma ukubunjwa kwesigaba.
Olo qeqesho lunabela kumalungiselelo. Iinxalenye ze-Sanicro28 zithumela i-vacuum-itywinwe ngephepha le-VCI-engagqunywanga ngeplastiki ebamba ukufuma. Amaxwebhu aquka iirekhodi zohlolo ezipheleleyo, hayi nje ingxelo yokuthotyelwa. Kwaye inkxaso yobunjineli iqala phambi kwe-PO: iqela lethu liphonononga i-GD&T yakho, lifaka iflegi enokubakho ukuphazamiseka komatshini kwi-tight-tolerance bores, kwaye icebisa iinguqu zeradiusing ukunciphisa uxinzelelo-simahla.
Ukukhetha i-Sanicro28 yakho ye-Stainless Steel Mechanical Parts Factory
Iqabane elifanelekileyo alicaphuli nje i-Sanicro28-bayaqonda ukuba kutheni ukhethe. Bayazi ukuba ukuphambuka kwe-0.02 mm kwi-groove yesitywina akukhona nje "ngaphandle kokunyamezela" - yindlela yokungena kwe-chloride. Abawuphathi umzobo wakho njengoluhlu lokutshekisha, kodwa njengemephu esebenzayo.
Ukuba isicelo sakho sifuna ukuxhathisa umhlwa, imfezeko yolwakhiwo phantsi komthwalo womjikelo, kunye nozinzo lwedimensional kuyo yonke imijikelo ye-thermal-ke ukuchaneka kubaluleke ngaphezu kwexabiso. Ufuna i I-Sanicro28 yensimbi engenasici kwifektri yomatshini elawula lonke ikhonkco: imathiriyeli ekrwada eqinisekisiweyo, ukusetyenzwa kwe-thermal esemgangathweni, ukuhlolwa komgangatho we-metrology, kunye nokulandeleka okubhaliweyo. Akukho namnye ojonga iibhokisi. Omnye othintela ukungaphumeleli ngaphambi kokuba kwenzeke.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha ezo ndawo-yonke imihla, kubathengi kulo lonke elaseYurophu, kuMntla Merika, nakuMzantsi-mpuma Asia. Ngenxa yokuba kwiimeko ezinzima, ukunyaniseka akukhethi. Yenziwe ngobunjineli.
