Xa usiva 'i-Sanicro 28 intsimbi yentsimbi engatyiwa ngamacandelo,' ingcinga ekhawulezileyo ihlala itsibela 'kwi-super austenitic, high corrosion resistance, ilungele imekobume erhabaxa.' Leyo yintetho yencwadana. Kwiworkshop, ibali limalunga nokulawula okulindelweyo-le alloy ayiyonto yomlingo. Isombulula iingxaki ezithile, eziqatha zomhlwa, kodwa uyilo lwayo, ngakumbi ulwakhiwo oluntsonkothileyo kunye nezinto ezingoomatshini, lwazisa uluhlu lwemicelimngeni angakulungiseleli yona amaxwebhu edatha. Umsantsa phakathi kweepropathi zayo zethiyori kunye nenyaniso yokuyijika ibe ngumzimba othembekileyo, othwele uxinzelelo lwevalve okanye i-pump casing apho amava, kwaye ngamanye amaxesha izifundo ezibizayo, zingena khona.
Isithembiso se-Alloy vs. Inyani yeMachinist
Ephepheni, Sanicro 28 uqaqambile. I-nickel ephezulu, i-chromium, kunye nomxholo we-molybdenum inika ukuxhathisa okumangalisayo kwi-pitting, i-crevice corrosion, kunye noxinzelelo lwe-corrosion cracking kwi-chlorides kunye ne-acidic media. Sithetha kude nonxweme, ukusetyenzwa kweekhemikhali, ukuchithwa kwerhasi yeflue—izinto ezimbi. Ndikhumbula iprojekthi yesixokelelwano sokupholisa amanzi olwandle apho iinxalenye ezingama-316L zazisilela kwisithuba seenyanga. Umxhasi uchaze i-Sanicro 28 njengotshintsho. Umtsi wentsebenzo wawungenakuphikiswa; ezo nxalenye zisasebenza. Kodwa ukufika apho kwakungathanga ngqo.
Umqobo wokuqala kukuqiniswa komsebenzi wayo. Iyabizwa. Ukuba inkqubo yakho ye-CNC kunye nesicwangciso sendlela yesixhobo siyiphatha njengomgangatho wama-304 okanye nokuba ngu-316, uya kutshisa ngokufaka, ubangele ubushushu obugqithisileyo, kwaye mhlawumbi usebenze-uqinise umphezulu ukuya kwinqanaba lokwenza iipasi ezilandelayo zibe nzima. Udinga ukuseta okuqinileyo, iijiyometri zerake eziqinisekileyo, kwaye ngokuqinisekileyo kufuneka ugcine ukutya okungaguqukiyo, okulawulwayo kunye nezantya. Vumela isixhobo sihlale, kwaye udale indawo enzima enokuthi iqalise ukuqhekeka kamva. Yimpahla efuna intlonipho kunye nokukhanya, ukubamba okubukhali.
Emva koko kukho itshiphu enentambo. Ayiqhekezi kakuhle. Ngaphandle kokulawulwa kwetshiphu ngendlela eyiyo—ngejiyometri yesixhobo, isipholisi soxinzelelo oluphezulu, okanye ukugqogqa okucwangcisiweyo—uphela unendlwane yentaka enokonakalisa umphezulu womsebenzi okanye, okubi ngakumbi, ibangele ukuntlitheka komatshini. Sifunde oku kwangethuba ekwenzeni ibhetshi yeeflange zesiko QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD.,(QSY). Iminyaka yabo engamashumi amathathu ekujuleni nasekusebenzeni kwakuthetha ukuba bayayiqonda impatho yemathiriyeli, kodwa nalapho, ukucofa iiparamitha ezifanelekileyo zejiyometri entsha, entsonkothileyo yayiyinkqubo yolingo kunye nempazamo kumgangatho wevenkile. Intsebenziswano yayingundoqo; amava abo esiseko kunye neempawu zokuqiniswa kwe-alloy zazise indlela yethu yokwenza.
Izinto ezintsonkothileyo zokuphosa: Apho iMicrostructure ibalulekile
Kulapho ke amalungu oomatshini uhambo ngokwenene luqala kumacandelo afana nemizimba yevalvu okanye izixhumi. Indlela yokuphosa ye-Sanicro 28 yahlukile. Ithambekele kulwahlulo oluncinci lwezinto ezidibanisayo, ngakumbi i-molybdenum, ngexesha lokuqina. Ukuba ukupholisa akulawulwanga ngokufanelekileyo-thi, kwinkqubo yokuphosa utyalo-mali loo nto QSY igcisa kwi-ungafumana usasazo olungalinganiyo lwezi zinto zibalulekileyo. Oku akuchaphazeli nje ukuxhathisa umhlwa ekuhlaleni; ichaphazela iimpawu zoomatshini ngokufanayo.
Umzekelo wenqaku: sakha safumana ukuphoswa kwekhonkco elibalulekileyo. Ipasile i-PMI esemgangathweni (i-Positive Material Identification) isheke. Kodwa phantsi komthwalo kwisimo sovavanyo, lusilele kwangethuba kwinqanaba loxinzelelo olubonakala lungenabungozi. Uhlalutyo lwe-Metallurgical lubonise imvula encinci ye-carbide ecaleni kwemida yeenkozo kwicandelo eliphole kancinci kancinci. I-chemistry eninzi yayilungile, kodwa i-microstructure yendawo yayiphazamisekile. Sifunda ntoni? Kuba Sanicro 28, inkqubo Foundry ulawulo-gating uyilo, ubushushu ethulula, ngundo pre-ubushushu, kunye post-casting ubushushu unyango (isisombululo annealing kunye nokucima)-ayiyo nje inyathelo; ngumba ochazayo wenxalenye yemfezeko. Isiseko esifana nesasemva https://www.tsingtaocnc.com edwelisa ialloys ezikhethekileyo ngokucacileyo uye wajijisana nale nuances, ukuphuhlisa izenzo zobunikazi ukuqinisekisa homogeneity.
Unyango lobushushu lwasemva kokuphoswa alunakuxoxisana. Ayilonyathelo ukuba liyafuneka. Ukugalela kufuneka kube sisisombululo esifakwe kubushushu obuphezulu (malunga no-°C ngokuqhelekileyo) kwaye emva koko kucinywe ngokukhawuleza ukunyibilikisa naziphi na izigaba zesibini kunye nokugcina zonke ezo zinto zixabisayo zokuhlanganisa kwisisombululo esiqinileyo. Nakuphi na ukutenxa apha, kwaye uvaleleka kubuthathaka phambi kokuba umatshini uqalise. Ngokusisiseko uhlawulela i-alloy yeprimiyamu kodwa ufumana ukusebenza okuphantsi.
I-Welding kunye ne-Fabrication Tightrope
Abaninzi intsimbi engenasici iindibano zifuna i-welding. Nge-Sanicro 28, i-welding luqeqesho ngokwayo. Umxholo wayo ophezulu we-alloy uthetha ukuba kunokwenzeka ukwenza izigaba zesibini ze-intermetallic kwindawo echaphazelekayo kubushushu (HAZ) ukuba igalelo lobushushu alilawulwa ngokungqongqo. Ezi zigaba, njengesigaba se-sigma, zinokutshabalalisa ngokupheleleyo ukuqina kunye nokumelana nomhlwa ekuhlaleni.
Senza iline enkulu, edityanisiweyo yegumbi. I-welds ibonakala ilungile, idlulile imbonakalo kunye nedayi yokuhlola ukungena. Kodwa kwinkonzo, iphuhlise ukuvuza ecaleni kwe-HAZ, hayi intsimbi yeweld ngokwayo. Umoni? Igalelo lobushushu obugqithisileyo ngexesha lencwadana yokupasa ye-TIG yokulungisa, engazange ibhalwe kwinkqubo. Yakha umtyana omxinwa wezinto ezibhityileyo eziye zonakaliswa ngokukhawuleza. Ukulungiswa kubandakanye ukufaneleka kwakhona yonke inkqubo ye-welding ye-welding (WPS) kunye nolawulo olungqongqo kwi-interpass yeqondo lokushisa kunye nokusetyenziswa kwesinyithi esihambelana ne-nickel ephezulu, njenge-Alloy 625 okanye i-Sanicro 28 filler ehambelanayo, ukugcina iprofayili yokubola. Sisikhumbuzo sokuba isakhono semathiriyeli sixhomekeke ekunyanisekeni kwayo yonke inkqubo ye-thermal ehamba nayo.
Le yenye indawo apho intsebenziswano nomnikezeli wenkonzo epheleleyo ibalulekile. Inkampani ephethe zombini ukuphosa / ukwenza kwaye iqonde iinkqubo zokujoyina ezantsi inokubonelela ngokuqhubekeka okuxabisekileyo. Banokucebisa malunga noyilo lokwenziwa kwezinto-njengokucebisa utshintsho oluncinci loyilo ukunciphisa umthamo we-weld okanye ukukhangela i-welds kude neendawo ezinoxinzelelo oluphezulu-ngokusekwe kwindlela izinto eziziphatha ngayo kulo lonke ikhonkco.
Iindleko-iNzuzo: Ukuthethelela iNtlawulo yaNyanga le
Masibe neentloni: I-Sanicro 28 iinxalenye ziyabiza. Ixabiso lempahla ekrwada liphezulu, umatshini uyacotha kwaye kudla izixhobo ezixabisa kakhulu, kwaye ulawulo olufunekayo lomgangatho wongeza ngaphezulu. Awuyichazi ngokuzonwabisa. Ukuthetheleleka ziindleko ezipheleleyo zomjikelo wobomi kwindawo etya ezinye izinto.
I-matrix yesigqibo iyasebenza. Ngaba yindawo engashukumiyo, enomhlwa kancinci? I-316L inokwanela. Ngaba i-chloride yoxinzelelo lwe-corrosion iqhekeza isoyikiso esiphambili? Mhlawumbi i-duplex 2205 inika amandla angcono-ibhalansi ye-corrosion ngexabiso eliphantsi. Kodwa xa ujongene ne-asidi ye-sulfuric eshushu, i-phosphoric kunye ne-fluorides, okanye amanzi olwandle ane-chlorination, kwaye ufuna i-ductility efanelekileyo kunye ne-weldability phezu kokumelana, yi-Sanicro 28 niche. Yingcaphephe, hayi i-generalist.
Kumenzi wokwenza izinto, oku kuthetha ukuba neengxoxo ezicacileyo kunye nabathengi. Ukubuyisela umva kwi-spec ebonakala igqithise, kodwa kunye nokuyithethelela xa isicelo sigunyazisa ngokwenene. Ndibone iiprojekthi apho iindleko zangaphambili zibangele ukothuka kwesincamathelisi, okukhokelela ekuthotyweni ukuya kwialloyi engabizi kakhulu. Kwiminyaka emibini emva koko, iindleko zexesha lokuphumla, ukutshintshwa, kunye nokugcinwa kokusingqongileyo ngenxa yokungaphumeleli kwanciphisa ugcino lokuqala. Ixabiso lokwenyani a Sanicro 28 steel stainless icandelo alikho kumgca womyalelo wokuthenga; ikumsebenzi wayo othe cwaka, othembekileyo iminyaka kwindawo apho kungekho nto iyenye ibambekayo.
Ukufumana kunye neNtsebenziswano: Umba oNgaphathekiyo
Awukwazi nje ukuthenga ezi nxalenye kwikhathalogu. Ukuvelisa Sanicro 28 amalungu oomatshini yintsebenziswano yobuchwephesha. Xa uvavanya umboneleli, awujongi nje oomatshini be-CNC; uphonononga ukuqonda kwabo ngesinyithi. Ngaba bafumana ukubaluleka kweetshathi zokunyanga ukushisa? Ngaba banokubonelela ngeengxelo zohlalutyo lwe-micrographic? Ngaba oomatshini babo bayayiqonda imvakalelo yento?
Yiyo loo nto amava omenzi achaziweyo, afana nemvelaphi ye-QSY yeminyaka engama-30 kutyalo-mali kunye nokwenza ii-alloys ezikhethekileyo, inobunzima. Kuthetha indawo yokugcina ulwazi olucekethekileyo-uhlobo olukhumbulayo ukuba yeyiphi isango eliye lanciphisa isiphithiphithi se-Ni-based alloy casting efanayo, okanye yeyiphi indlela yokupholisa esebenze ngcono ukulawula ukunamathela kwetshiphu. Iwebhusayithi yabo, https://www.tsingtaocnc.com, udwelisa i-cobalt kunye ne-nickel alloys ecaleni kwe-stainless, oluphawu oluhle; icebisa ukuqhelana nentsapho yonke yezinto ezicela umngeni, eziphezulu zokusebenza.
Ubudlelwane buba yintsebenziswano yobugcisa. Ezona ziphumo zingcono endizibonileyo ziquka ukwabelana ngenkonzo epheleleyo ngemekobume yenkonzo (amaqondo obushushu, ugxininiso lweekhemikhali ezichanekileyo, imithwalo yokuhamba ngebhayisikile) kunye nomseki kunye noomatshini. Oku kubavumela ukuba benze uhlengahlengiso olufihlakeleyo-mhlawumbi i-tweak encinci kwixesha lesisombululo, okanye isincomo sokugqiba umphezulu othile ukunciphisa umngcipheko wokuqalisa. Inxalenye iba sisisombululo esihlangeneyo, kungekhona nje into ethengiweyo. Kwihlabathi le-alloys eziphezulu, obo bunzulu bentsebenziswano buhlala bungumahluko phakathi kwenxalenye edibana nje noshicilelo kunye neyona igqwesileyo kwinkonzo.
