Ukutsalwa kwesisombululo, okwaziwa ngokuba lunyango lwesisombululo, yinkqubo yonyango lobushushu esetyenziselwa ukuphucula ukumelana nokugqwala, iimpawu zoomatshini, kunye nokufana kwesakhiwo sentsimbi engagqwali.
Yintoni i-annealing?
Ukuqokelelayinkqubo yokunyanga ubushushu eyenzelwe ukuphucula ukuguquguquka nokusebenza kakuhle kwezinto ngokunciphisa ubulukhuni nokunciphisa uxinzelelo lwangaphakathi. Le nkqubo ibandakanya ukufudumeza okulawulwayo ukuya kubushushu obuthile, kugcinwe kuloo bushushu ukuvumela utshintsho lwesakhiwo, kuze kuphole kancinci—ngokuqhelekileyo kwisithando somlilo. Ukuqhoboshela kuphucula ulwakhiwo lwezixhobo, okwenza zifane kwaye zizinzile. Zisetyenziswa rhoqo kwiintsimbi ezifana nentsimbi, ubhedu, kunye nobhedu, kunye nezinto ezifana neglasi kunye neepolymers ezithile ukuze kuphuculwe iimpawu zazo zoomatshini kunye nokucubungula.
Yintoni i-Annealed Stainless Steel?
Intsimbi engagqwaliyo efakwe kwi-Annealedyintsimbi engagqwaliyo eye yafumana unyango lobushushu olushushu ukuze iphucule iimpawu zayo. Le nkqubo ibandakanya ukufudumeza intsimbi ukuya kubushushu obumiselweyo uze uyipholise kancinci ukuze kuncitshiswe uxinzelelo lwangaphakathi, kuphuculwe ukuqina kwayo, kwaye ithambise izinto. Ngenxa yoko, intsimbi engagqwaliyo egqwalisiweyo inika amandla okusebenza aphezulu, ukwakheka okuphuculweyo, kunye nokumelana nokugqwala okuphuculweyo xa kuthelekiswa nomlingani wayo onganyangwanga.
Iyintoni Injongo Yokutsalwa Kwentsimbi Engagqwaliyo?
1. Susa ii-Intergranular Precipitates kwaye ubuyisele uxhathiso lokugqwala
Ngokunyibilikisa ii-carbides ze-chromium (umz., i-Cr₃C₂) zibuyele kwi-austenitic matrix, unyango lwesisombululo luthintela ukwakheka kweendawo eziphelelwe yi-chromium, nto leyo ephucula ngempumelelo ukumelana nokugqwala kwe-intergranular.
2. Fumana isakhiwo esifana nesase-Austenitic Microstructure
Ukufudumeza intsimbi engagqwaliyo kubushushu obuphezulu (ngesiqhelo i-1050°C–1150°C) kulandele ukucima ngokukhawuleza okuphumela kwinqanaba elifanayo nelizinzileyo le-austenitic, nto leyo ephucula ukusebenza kakuhle kwezinto.
3.Phucula iDuctility kunye noBulukhuni
Olu nyango lunciphisa uxinzelelo lwangaphakathi kwaye lukhuthaza ukucocwa kweenkozo, nto leyo ekhokelela ekubeni zikhule kakuhle kwaye zikwazi ukumelana neempembelelo.
4. Ukuphucula ukusebenza kakuhle
Kwintsimbi ezingenasici ezisebenza ngokubandayo, i-solution annealing isusa iziphumo zokuqina komsebenzi, nto leyo eyenza kube lula ukugaya nokuyila kwi-processing elandelayo.
5. Lungisa izinto ezifunekayo ukuze ufumane unyango oluthe kratya lobushushu
Ukuqhoboshela isisombululo kubonelela ngesiseko esifanelekileyo sezakhiwo ezincinci kwiinkqubo ezinje ngokuguga okanye ukuwelda, ingakumbi kwiintsimbi ezingenasici eziqiniswe yimvula okanye ezimbini.
Imizekelo yeentlobo zentsimbi ezisebenzayo
• Intsimbi engagqwaliyo yase-Austenitic (efana ne-304, 316, 321): Susa ukurhawuzelelwa kokugqwala phakathi kwe-granular
• Intsimbi engagqwaliyo eqinisa imvula (efana ne-17-4PH): Unyango lwesisombululo lulandelwa kukwaluphala
• Intsimbi engagqwaliyo ephindwe kabini (efana ne-2205, 2507): Unyango lwesisombululo lusetyenziselwa ukufumana umlinganiselo ofanelekileyo we-austenite + ferrite
