Ukuthuthukisa Ukusebenza Ngezintambo Zokushisela Ze-Nickel Alloy Eziphezulu

Ezweni elisheshayo lokushisela nokubopha, ochwepheshe bayaqonda ukubaluleka okubalulekile kokusebenzisa izinto ezisezingeni eliphezulu ukuze kutholakale imiphumela engenaphutha. Yilapho izintambo ze-alloy ezine-nickel ephezulu zisebenza khona. Njengoba zenzelwe ngqo ukushisela nokubopha ama-alloy asekelwe ku-nickel njengezinto ezingu-625 noma ezifanayo, le ntambo yenzelwe ukudlula okulindelwe maqondana nokusebenza kahle, ukuqina kanye nokuguquguquka. Yakhelwe ukuletha ukushisela okuhlanzekile, okuseqophelweni eliphezulu ngendlela eqinile, le ntambo ivelele emakethe ngenxa yokuguquguquka kwayo okuphezulu kanye nokushisela okukhazimulayo.

Enye yezinzuzo eziphawuleka kakhulu ze-ucingo lokuwelda lwe-nickel alloy oluphezuluiyizakhiwo zayo ezinhle kakhulu zomshini kokubili emazingeni okushisa aphezulu naphansi. Kungakhathaliseki ukuthi imvelo injani, ochwepheshe bangaqiniseka ukuthi le ntambo yokushisela izoqhubeka nokubonisa ukuqina okumangalisayo kanye nobuqotho besakhiwo. Ngaphezu kwalokho, le nsimbi yokushisela inokumelana okuhle kakhulu nokugqwala kwemigodi nokucindezela, okwenza ifaneleke kakhulu kumaphrojekthi afana nemboni yezinqubo zamakhemikhali, ubunjiniyela basolwandle, izingxenye ze-reactor yenuzi, izindiza kanye nemishini yokulawula yezepolitiki.

Ukugcina ubuqotho nokusebenza kubalulekile lapho usebenza ngama-alloy aphezulu e-nickel nezinto ezifanayo.Izintambo zokushisela ze-nickel alloy ephezuluzenzelwe ukuqinisekisa imiphumela efanayo ngisho nangaphansi kwezimo ezinzima. Intambo isebenza ngaphezu kobubanzi bokushisa obunconywayo kusukela ku-cryogenic kuya ku-540°C, okunikeza ukuthula kwengqondo ekuvikeleni ekushintsheni kokushisa. Lokhu kuwusizo ikakhulukazi ezisetshenzisweni ezibalulekile lapho ukuzinza kubalulekile ekusebenzeni okuthembekile.

Ngaphezu kwalokho,ucingo lokuwelda lwe-nickel alloy oluphezuluivula indlela yokwanda kokukhiqiza nokusebenza kahle. Ngobuchwepheshe bayo obuqinile bokumapha, yenza kube lula inqubo yokunamathisela ebushelelezi nengenamthungo, inciphisa amaphutha futhi ilungise kabusha. Lokhu akugcini nje ngokusindisa isikhathi esibalulekile, kodwa futhi kunciphisa ukuchithwa kwezinto ezibonakalayo, okwenza kube ukukhetha okungabizi kakhulu kwezimboni ezahlukene. Umphumela wokugcina ukushibiliza okunembile, okuhlanzekile okunokuguquguquka okuhle kakhulu, okuqinisekisa ukusebenza okuhlala isikhathi eside ngisho nangaphansi kwezimo ezinzima.

Ngamafuphi, ama-electrode e-alloy ane-nickel ephezulu anikeza izinzuzo eziningi kochwepheshe embonini yokushisela nokumboza. Amandla ayo okushisela nokumboza kalula ama-alloy asekelwe ku-nickel, kufaka phakathi i-625, anikeza ikhambi elithembekile lezinhlelo zokusebenza ezahlukahlukene. Kusukela ekuletheni ama-weld acwebezelayo, asezingeni eliphezulu kuya ekuboniseni izakhiwo ezinhle kakhulu zemishini emazingeni okushisa aphezulu, le ntambo ivumela ochwepheshe ukuthi bathole imiphumela emihle kakhulu. Ngekhono layo lokumelana nokugqwala nokugqwala, ibonakalise ukuthi iyisinqumo esiqinile nesithembekile. Ukusetshenziswa kweizintambo zokushisela ze-nickel alloy ephezulukuvula amathuba amasha futhi kuqinisekisa ukuqedwa ngempumelelo kwamaphrojekthi emikhakheni eyahlukahlukene njengezinqubo zamakhemikhali, ubunjiniyela basolwandle kanye nezindiza.
