Kusiyana pakati pa kugudubuza kozizira ndi kugudubuza kotentha

Kusiyana kwa kugudubuza kozizira ndi kugudubuza kotentha ndiko makamaka kutentha kwa njira yogudubuza.“Kuzizira” kumatanthauza kutentha kwabwinobwino, ndipo “kutentha” kumatanthauza kutentha kwambiri.Kuchokera pamalingaliro a metallographic, malire pakati pa kuzizira kozizira ndi kugudubuza kotentha ayenera kusiyanitsidwa ndi kutentha kwa recrystallization.Ndiko kuti, kugubuduza pansi kutentha recrystallization ozizira anagubuduza, ndi anagubuduza pamwamba recrystallization kutentha ndi otentha anagubuduza.Kutentha kwa recrystallization chitsulo ndi 450 mpaka 600°C. Kusiyanitsa kwakukulu pakati pa kugudubuza kotentha ndi kuzizira kozizira ndi: 1. Mawonekedwe ndi khalidwe lapamwamba: Popeza mbale yozizira imapezeka pambuyo pa ndondomeko yozizira ya mbale yotentha, ndipo kutsirizitsa kwina kudzachitika nthawi yomweyo, pamwamba pa mbale ozizira (monga Surface roughness, etc.) ndi bwino kuposa mbale otentha, kotero ngati pali chofunika kwambiri ❖ kuyanika khalidwe la mankhwala, monga post-penti, mbale ozizira nthawi zambiri amasankhidwa, ndi otentha mbale lagawidwa pickling mbale ndi sanali pickling mbale.Pamwamba pa mbale zoziziritsa kukhosi zimakhala ndi mtundu wachitsulo wabwinobwino chifukwa cha pickling, koma pamwamba sipamwamba ngati mbale yozizira chifukwa sizizira.Pamwamba pa mbale yosasankhidwa nthawi zambiri imakhala ndi oxide wosanjikiza, wosanjikiza wakuda, kapena chitsulo chakuda cha tetroxide.M'mawu a layman, zikuwoneka ngati zowotcha, ndipo ngati malo osungiramo si abwino, nthawi zambiri amakhala ndi dzimbiri pang'ono.2. Magwiridwe: Kawirikawiri, makina opangira mbale yotentha ndi mbale yozizira amaonedwa kuti ndi osadziwika bwino mu engineering, ngakhale kuti mbale yozizira imakhala ndi gawo lina la ntchito yowumitsa panthawi yozizira, (koma sichilamulira. tulutsani zofunikira zamakina amakina. , ndiye kuti ziyenera kuchitidwa mosiyana), mphamvu ya zokolola za mbale yozizira nthawi zambiri imakhala yokwera pang'ono kuposa mbale yotentha, komanso kuuma kwapamtunda kumakhalanso kokwera, kutengera kuchuluka kwa annealing. wa mbale ozizira.Koma ngakhale atatsekeredwa bwanji, mphamvu ya mbale yozizira imakhala yayikulu kuposa ya hot plate.3. Kupanga ntchito Popeza ntchito ya mbale zozizira ndi zotentha sizili zosiyana kwambiri, zomwe zimapangitsa kuti apange ntchito zimadalira kusiyana kwapamwamba.Popeza khalidwe lapamwamba liri bwino kuchokera ku mbale zozizira, nthawi zambiri, mbale zachitsulo zomwezo zimakhala ndi zinthu zomwezo., kupangika kwa mbale yozizira kumakhala bwino kuposa mbale yotentha.
