Ukufakwa kwe-solution annealing, okwaziwa nangokuthi ukwelashwa kwe-solution, inqubo yokwelapha ukushisa esetshenziswa kakhulu ukuthuthukisa ukumelana nokugqwala, izakhiwo zemishini, kanye nokufana kwesakhiwo sensimbi engagqwali.
Kuyini ukubopha?
Ukufakwa kwe-Annealingkuyinqubo yokwelapha ukushisa eyenzelwe ukuthuthukisa ukuguquguquka nokusebenza kahle kwezinto ngokunciphisa ubulukhuni nokunciphisa ukucindezeleka kwangaphakathi. Le nqubo ihilela ukushisa okulawulwayo kuze kufike ekushiseni okuthile, kubambe kulelo zinga lokushisa ukuze kuvunyelwe ukuguqulwa kwesakhiwo, bese kupholisa kancane—ngokuvamile esithandweni somlilo. Ukuhlanganisa kuthuthukisa isakhiwo sezinto, okwenza zifane futhi ziqine. Ngokuvamile kusetshenziswa ezinsimbini ezifana nensimbi, ithusi, nethusi, kanye nasezintweni ezifana nengilazi kanye nama-polymer athile ukuze kuthuthukiswe izakhiwo zazo zomshini nezokucubungula.
Iyini i-Annealed Stainless Steel?
Insimbi engagqwali ehlanganisiweiyinsimbi engagqwali eye yaphathwa ngokushisa okuncibilikisiwe ukuze ithuthukise izici zayo. Le nqubo ihilela ukufudumeza insimbi ibe yizinga lokushisa elibekiwe bese iyipholisa kancane ukuze inciphise ukucindezeleka kwangaphakathi, ithuthukise ukuqina kwayo, futhi ithambise izinto. Ngenxa yalokho, insimbi engagqwali encibilikisiwe inikeza ukusebenza kahle kakhulu, ukwakheka okuthuthukisiwe, kanye nokumelana nokugqwala okuthuthukisiwe uma kuqhathaniswa nomlingani wayo ongaphathwanga.
Iyini Inhloso Yokunamathela Ngensimbi Engagqwali?
1. Susa Izimvula Eziphakathi Kwezinhlayiya Futhi Ubuyisele Ukumelana Nokugqwala
Ngokuncibilikisa ama-carbide e-chromium (isb., i-Cr₃C₂) abuyele ku-austenitic matrix, ukwelashwa kwesisombululo kuvimbela ukwakheka kwezindawo eziphelelwe yi-chromium, okuthuthukisa ngempumelelo ukumelana nokugqwala kwe-intergranular.
2. Finyelela isakhiwo esincane se-Austenitic esifanayo
Ukushisa insimbi engagqwali kuze kufike emazingeni okushisa aphezulu (ngokuvamile 1050°C–1150°C) kulandelwa ukucima okusheshayo kuphumela esigabeni esifanayo nesizinzile se-austenitic, okuthuthukisa ukusebenza kwezinto ezisetshenziswayo.
3. Thuthukisa Ukuqina Nokuqina
Ukwelashwa kunciphisa ukucindezeleka kwangaphakathi futhi kukhuthaza ukuhluzwa kokusanhlamvu, okuholela ekwakhekeni okungcono kanye nokumelana nokushayisana.
4. Thuthukisa Ukuguquguquka Kwemishini
Ngezinsimbi ezingagqwali ezisebenza ngokubandayo, ukuncibilikisa isixazululo kususa imiphumela yokuqina komsebenzi, okwenza kube lula ukugaya nokwakha ekucutshungulweni okulandelayo.
5. Lungiselela Izinto Zokwelapha Ukushisa Okuqhubekayo
Ukuxutshwa kwesisombululo kunikeza isisekelo esifanele sezakhiwo ezincane zezinqubo ezinjengokuguga noma ukushisela, ikakhulukazi izinsimbi ezingagqwali eziqiniswe yimvula noma ezimbili.
Izibonelo zezinhlobo zensimbi ezisebenzayo
• Insimbi engagqwali yase-Austenitic (njenge-304, 316, 321): Susa ukuthambekela kokugqwala phakathi kwe-granular
• Insimbi engagqwali eqinisa imvula (njenge-17-4PH): Ukwelashwa kwesisombululo kulandelwa ukuguga
• Insimbi engagqwali ephindwe kabili (njenge-2205, 2507): Ukwelashwa kwesixazululo kusetshenziselwa ukuthola isilinganiso esifanele se-austenite + ferrite
