Emitendera esatu n'ebivaamu mu nkola ya annealing .

Mu nkola y'okujingirira ekyuma ekitali kizimbulukuse, 'annealing' nkola nkulu. Annealing kyetaagisa okukozesa ebyuma ebikuba ebyuma ebizimba omubiri (annealing furnaces), ebikoomi ebitangaavu (bright annealing furnaces) bisinga kukozesebwa mu kulongoosa ebbugumu eriwedde ery’ekyuma ekitali kizimbulukuse mu mbeera ey’obukuumi. Omutindo gwa njawulo, ebyetaago by’ebikoomi ebitangaavu eby’okusengejja (bright annealing furnaces) bya njawulo, era n’amakolero agakola ebbugumu si ge gamu. Enkola eya bulijjo ey’okulongoosa ebbugumu eya 300 series austenitic stainless steel payipu ye solid solution treatment. Ekisumuluzo ky’enkola eno ey’okulongoosa ebbugumu kwe kunyogoga okw’amangu, okuva ku 1050 okutuuka ku 1150 ° C, okukuuma ebbugumu okusaanidde okumala ekiseera ekitono, bwe kityo carbide yonna esaanuuse mu austenite, n’oluvannyuma n’etonnya mangu okutuuka wansi wa 35 ° C. 400 series ferritic stainless stainless pipe temperature okusinga nga ekozesa slow cooling slow cooling to obtained annealed structureed structureed.

Era, emitendera esatu egya 'annealing' gijja kufuula payipu yo ey'ekyuma okumasamasa era ewangaala. Ekisooka, omutendera gw’ebbugumu, payipu y’ekyuma ekitali kizimbulukuse eri mu kyokero ekiggaddwa, era kyetaagisa okulaba ng’ekifo payipu y’okuyingira n’okufuluma ekuumibwa nga esibiddwa era tewali kukulukuta kwa mpewo kukkirizibwa. Olw’okuba kibuguma mu mbeera ekendeeza omukka ogutaliiko maanyi ne haidrojeni eya bulijjo, ebbugumu erimu lituuka, era empeke z’ekyuma zizzibwawo mu mbeera eya kimu era ennungi. Ekirala, omutendera gw’okuziyiza amazzi, ebbugumu lya payipu y’ekyuma ekitali kizimbulukuse (stainless steel pipe) liziyizibwa era ne litebenkeza okumala ekiseera ekigere okuyita mu kitundu eky’okuziyiza, okusobola okumalawo obulungi okusobola kw’obutaba na boundary chromium ebbula lya chromium n’okwewala okutondebwa kw’okukulukuta okw’omu makkati. Payipu y’ekyuma oluvannyuma lw’okulongoosa okutebenkeza erina ebyuma ebirungi n’okuziyiza okukulukuta. Ekyokusatu, omutendera gw’okunyogoza, payipu y’ekyuma ekitali kizimbulukuse ekozesa haidrojeni mu kyokero ekiggaddwa okutuuka ku nkola y’okunyogoza okw’amangu, okusaasaana kw’ebbugumu ly’omukono gwa graphite n’enkola y’amazzi agakulukuta biggyawo ebbugumu, n’ensonga y’okuzimbulukuka okutangaavu n’omuwendo omutono ogwa haidrojeni okwewala okufuuka omukka n’okuggyibwako kaboni, n’okufuna ku ngulu awatali kuziyiza kuzimba bulungi n’okuziyiza okulungi.

Mu nkola y’okukola ‘annealing’, waliwo n’ebyetaago ebimu eby’ekikoomi ekikola ku kuzimba (annealing furnace), era okufaayo kulina okussibwako essira ku kukuuma ekikoomi ekizimba omubiri (annealing furnace). Ekikoomi ekikola annealing kikozesa haidrojeni nga omukka ogw’obukuumi. Hydrogen bw’emala okukulukuta, kiyinza okuba eky’obulabe okusituka n’okukuŋŋaanyizibwa mu kizimbe ky’omunaala. Kale tulina okukola ku nsonga ezikwatagana okulaba ng’obukuumi.
