Ubona i-alloy 20 kwiphepha elithile, kwaye ingcamango yokuqala ihlala i-nickel-resistant-resistant alloy, idibanisa kunye ne-Hastelloys kunye ne-Inconel. Kulapho ukwenza lula kakhulu kuqala. Enyanisweni, ukuziphatha kwayo, ngakumbi kwimveliso kunye nomatshini, ihleli kule ndawo inqabileyo, ngamanye amaxesha iyakhathazayo, iphakathi. Ayikokuxolela njenge-316L, kodwa ayiyaleli intlonipho egqithileyo njenge-C-276. Ndibone iiprojekthi zikhubeka ngokuphatha njengazo.
INyaniso yeFabricator: ukuWelding kunye nokwenza iiNuances
Apho ufunda khona nge-alloy evenkileni, hayi kwi-database. Nge-Alloy 20, inkqubo ye-welding ibalulekile. Izinzisiwe kunye ne-niobium, kodwa loo nto ayiyenzi ukuba ikhuseleke kwi-sensitization ukuba awukhathali ngokufaka ubushushu. Ndikhumbula ibhetshi yeentloko ezenziweyo zenkonzo ye-phosphoric acid apho iiwelds zazijongeka zigqibelele kodwa zasilela kwangaphambi kwexesha kwindawo echaphazeleke bubushushu. Ingxaki? Ubushushu be-Interpass bebuphezulu kakhulu. I-spec ithi gcina ngaphantsi kwe-150 ° C, kwaye abasebenzi baye bayeka, becinga ukuba i-nickel alloy inokuyithatha. Ayikwazanga. La mava aqinisa umthetho: phatha umjikelo we-thermal ngendlela efanayo njengoko ubuya kwenza kwi-alloy engaqhelekanga.
Ukubumba yenye ingongoma. Ine-ductility ehloniphekileyo, kodwa izinga layo lokuqiniswa komsebenzi libalulekile. Ukuba wenza ukwakheka okubandayo, uxinzelelo lwezixhobo lufuna uhlengahlengiso xa kuthelekiswa namabakala asezantsi e-austenitic. Kuye kwafuneka siphinde sisike iiroli zeqokobhe kunye netyhubhu yokutshintshisa ubushushu kube kanye ngenxa yokuba ukuphumelela kokuqala kubangele ukuqina okukhulu, okukhokelela kwii-microcracks ngexesha lokucheba okulandelayo. Yimathiriyeli efuna ukuba ucwangcisele i-springback kunye nokonyuka kwamandla emva kwenyathelo ngalinye lokuguqula.
Kulapho amava e-Foundry abalulekileyo. Iqabane elinje Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka yabo ekujuleni nasekwenzeni, ngokwesiqhelo ezi parameters ziye zifowunele. utyalo mali iinkqubo ezine-alloys ezinje, ukulawula izinga lokuqiniswa kunye nokuphathwa kokushisa emva kokuphoswa akuxoxiswana ukufezekisa ukuhanjiswa okufanelekileyo kwe-carbide kunye nokuphepha iindawo zokukhaba i-corrosion yendawo.
Machining: Ibhalansi ethambileyo yeTough kunye neGummy
Ukuba wenze kuphela iintsimbi ezingama-304 okanye iintsimbi ezimbini, iAlloy 20 iya kuziva yahlukile. Ayisiyonto inzima kakhulu phaya, kodwa iqinile. Ayiqhekezi itshiphu ngokucocekileyo; ithanda ukwenza i-swarf emide, enentambo enokwenza umonakalo ukuba ayilawulwa. Isitshixo sibukhali, i-positive-rake tooling kunye nokuhambelana, ukondla okuphakathi kunye nezantya. Ukusikwa okunobundlongondlongo kukhokelela kumphetho owakhiweyo kunye nokuphela komphezulu obuthathaka.
Oku sikufunde kumsebenzi we-pump shaft. Ukusebenzisa iiparamitha ezifanayo njenge-17-4PH engenastainless kubangele ukunxitywa kwesixhobo esikhawulezayo kunye nomphezulu wejenali amanqaku. Ukuxhasa isantya, ukonyusa ukutya kancinane (okuchaseneyo, kodwa kuyanceda ekwaphuleni itshiphu), kunye nokusebenzisa isisipholisi se-lubricity ephezulu kwenza wonke umahluko. Isixhobo sinendlela yokukuxelela xa ungalunganga.
Kumacandelo antsonkothileyo, kulapho kuhlanganiswe khona CNC Machining ubunakho buba yinzuzo enkulu. Umboneleli ophethe zombini ukuphosa kunye nokugqiba machining, njengeenkonzo ezichazwe kuyo tsngtaocnc.com, inokwandisa wonke umsebenzi. Banokushiya izibonelelo ezifanelekileyo zesitokhwe ukusuka kwinqanaba lokuphosa, besazi kakuhle ukuba oomatshini babo baya kujongana njani nokusikeka kokugqibela kule alloy ethile, ukuphepha uxinzelelo lokuhambisa i-semi-finished, i-casted casting kwenye ivenkile yomatshini.
Umxholo we-Alloy oKhethekileyo kunye noKhetho lweMathiriyeli
I-alloy 20 idla ngokuhlelwa phantsi kwee-alloys ezikhethekileyo, kwaye ngokufanelekileyo. Kodwa kubalulekile ukuchaza ukuba ilungiselelwe ntoni. Indawo yayo eswiti ziindawo zeasidi yesulfuric, ngakumbi apho kukho iikloridi. Kukuhamba-kuya kwiitanki ezininzi zokuxuba, imibhobho, kunye nokufakwa kwimichiza. Nangona kunjalo, ndiyibonile isetyenziswa gwenxa kulindelo lokuchasa jikelele. Ayilungele iimeko ze-oxidizing kakhulu okanye i-hydrofluoric acid, umzekelo.
Ukuyikhetha kudla ngokuhla kuhlalutyo lwexabiso lokusebenza ngokuchasene ne-alloys ephezulu ye-nickel. Kwiprojekthi enye yesityalo esiphakathi esixuba amayeza, uyilo lokuqala lwabiza iHastelloy C-22 yenkqubo yereactor epheleleyo. Uphononongo lucebise ukuba kubushushu obuthile kunye noxinzelelo lwe-asidi ye-sulfuric ekhoyo, Ingxubevange 20 yayingaphezulu kokwaneleyo. Olu tshintsho lugcine iindleko ezinkulu ngaphandle kokubeka esichengeni ubomi benkonzo. Lilo ixabiso lokuchaneka, hayi ukugcinwa ngokugqithisileyo, ukukhetha izinto eziphathekayo.
Oku kuhambelana nepotfoliyo yengcali efana ne-QSY. Umsebenzi wabo kunye ialloys esekwe nickel kwaye ialloys esekwe cobalt kuthetha ukuba bayayiqonda le nkqubo yokukhetha imigangatho. Abathengisi nje isinyithi; badla ngokubandakanyeka kudliwano-ndlebe kwangethuba ukufumanisa ukuba i-Alloy 20 ifanelekile na, okanye ukuba iimeko zenkonzo zifuna inyathelo ukuya kwinto eyomelele ngakumbi, abanokuthi babonelele ngayo.
Iingqwalasela zokuLahla: Ukuvakala kunye neenkcukacha
Casting Alloy 20, ingakumbi nge iqokobhe ngundo ukuphosa okanye utyalo mali Iindlela iQSY igxile kuyo, inikezela ngeyayo imingeni. I-alloy inomlinganiselo ophezulu wokunyibilika kunye neempawu ezithile zokushwabana. Ukufumana isandi, ukuphosa okuxineneyo ngaphandle kokushwabana kwe-porosity okanye iinyembezi ezishushu, i-gating kunye noyilo lwenkqubo yokunyuka kubaluleke kakhulu. Asiyonto yokugalela ulibale.
Ndiye ndahlola imizimba yevalve apho umhlwa uqalile kwimingxuma yangaphakathi encinci ye-shrinkage engabonakaliyo kwi-RT. I-Foundry isebenzise uyilo olunyukayo olulungele ngcono i-carbon steel. Ulungiso lubandakanya ukutshintshela kwizinyusi eziphuma ngaphandle ukuze kugcinwe isinyithi sinyibilika ixesha elide kunye nokukhuthaza ukuqina kwecala. Ubuchwephesha bobunjineli bepatheni ye-Foundry buvavanywa ngokuthe ngqo apha.
Inzuzo yokusebenza ixesha elide lithala leepateni eziqinisekisiweyo kunye nobuchule abakhayo. Kumacandelo aphindaphindayo afana neecasings zempompo okanye i-impellers kwi-Alloy 20, le datha yenkqubo yembali ixabiseke kakhulu ekuqinisekiseni ukuhambelana kunye nomgangatho ukusuka kwithululo lokuqala ukuya kwikhulu.
Enkonzweni: Iwotshi yexesha elide
Ubungqina bokugqibela balo naluphi na ukhetho lwezinto eziphathekayo lukwinkonzo. I-alloy 20 components idinga ishedyuli yokuhlola isiseko, ngakumbi kwii-welds kunye neendawo ezinoxinzelelo oluphezulu. Sakhe salandelela iseti yeetyhubhu zokutshintsha ubushushu kwiminyaka emihlanu. Isixhobo somzali sasingenasiphako, kodwa i-tube-to-tubesheet welds ezimbalwa zabonisa iimpawu zohlaselo oluncinci kakhulu lomgca wemela. Yayingengokusilela, kodwa yaqaqambisa ukuba kwanodibaniso oludityanisiweyo kakuhle yeyona ndawo isesichengeni. Isisombululo ibingekokutshintsha ialloyi, kodwa kukuphumeza inkqubo yokuhlola ekujoliswe kuyo ngakumbi kwezo zidityanisiweyo ngexesha lokuvalwa.
Ikwanazo neempawu zoomatshini ezilungileyo kumaqondo obushushu aphakathi, kodwa awufuni ukutyhala amandla ayo okurhubuluza. Kubushushu obuphezulu, imigca yesulfuri enoxinzelelo oluphezulu, inokuba lukhetho olungalunganga. Kwakhona, imalunga nokwazi indlela yayo.
Ekugqibeleni, ukusebenza kunye ne-Alloy 20 imalunga nokuhlonipha ubuntu bayo obuthile. Sisixhobo sobunjineli esiluncedo kakhulu esizalisa umsantsa obalulekileyo phakathi kweentsimbi ezikumgangatho ophantsi kunye neealloyi zenickel zeprimiyamu. Kodwa ixabiso layo liqondwa ngokupheleleyo kuphela xa uvuma ama-nuances ayo ekwenziweni, ekwenzeni, kunye nokusetyenziswa. Asiyonto yorhwebo; sisixhobo esichanekileyo. Kwaye njengaso nasiphi na isixhobo esichanekileyo, ukusebenza kwayo kuxhomekeke kakhulu kwisakhono sabantu abachazayo, ukuphosa, ukwenza, kunye nokuyifaka njengoko yenzayo kwi-chemistry yealloy ngokwayo.
