Nthawi zambiri, kutenthetsera komwe kutayika koyaka ndi 0.5% kapena kucheperako kumakhala kocheperako, ndipo kutentha komwe kutayika koyaka ndi 0.1% kapena kucheperako kumatchedwa Kutentha kopanda oxidizing. Kutentha kopanda makutidwe ndi okosijeni kumatha kuchepetsa kutulutsa kwachitsulo ndi decarburization, kuwongolera kwambiri mawonekedwe apamwamba komanso kulondola kwazomwe zimapangidwira, ndikuchepetsa kuvala kwa nkhungu. Ukadaulo wocheperako wopanda oxidation ndi ukadaulo wofunikira kwambiri pakupangira molondola. Ukadaulo uwu sunachitikebe kafukufuku wambiri ku China.
Pali njira zambiri zopezera kutentha kopanda okosijeni. Njira zomwe zimagwiritsidwa ntchito kwambiri komanso zomwe zikukula mwachangu ndizomwe zimatetezedwa mwachangu, zapakatikati, komanso kutentha pang'ono kwa lawi la oxidizing.makina gawo
1, Kutentha kofulumira
Kutentha kofulumira kumaphatikizapo kutenthetsa mwachangu ndi kutenthetsa mwachangu, kutenthetsa kwamagetsi olowetsamo, ndikuyatsa magetsi mung'anjo yamoto. Zomwe zimayambira pakuwotcha mwachangu ndikuti chitsulo chikakhala chotenthedwa pamoto wotenthetsera mwaukadaulo, kukwera kwamphamvu kwa kutentha, kupsinjika kotsalira, komanso kupsinjika kwa minofu komwe kumapangidwa mkati mwa billet sikukwanira kuyambitsa kusweka kwa billet. Njira imeneyi angagwiritsidwe ntchito yaing'ono kakulidwe carbon steel ingots ndi akusowekapo kwa ambiri forging akalumikidzidwa osavuta. Popeza ndondomeko yomwe ili pamwambayi imakhala ndi kutentha kwakukulu, nthawi yotentha imakhala yochepa, ndipo chigawo cha oxide chomwe chimapangidwa pamwamba pa billet ndi chochepa kwambiri, choncho cholinga cha okosijeni ndi chaching'ono.
Mukamagwiritsa ntchito kutentha kwa induction, kuyatsa kwachitsulo kumakhala pafupifupi 0.5%. Gasi woteteza atha kulowetsedwa mu ng'anjo yotenthetsera kuti akwaniritse zofunikira kuti pasakhale kutentha kwa okosijeni. Mpweya wotchinjiriza ndi mpweya wa inert monga nayitrogeni, argon, helium, kapena zina zotero, ndi mpweya wochepetsera monga wosakaniza wa CO ndi H2, wokonzedwa mwapadera ndi chipangizo chotetezera gasi.CNC
Popeza kutentha kwachangu kumafupikitsa nthawi yotentha, kuchuluka kwa decarburization kumatha kuchepetsedwa kwambiri ndikuchepetsa makutidwe ndi okosijeni, komwe kumakhala kosiyana ndi kutentha kwa lawi la oxidizing, chimodzi mwazabwino kwambiri pakuwotcha mwachangu.pulasitiki gawo
2, Kutentha kwapakati pachitetezo chamadzi
Standard madzi chitetezo TV ndi galasi wosungunuka, mchere wosungunula, etc. The mchere kusamba ng'anjo Kuwotha anafotokoza mu gawo loyamba la Chapter 2 ndi mtundu wa madzimadzi sing'anga chitetezo Kutentha.
Chithunzi 2-24 chikuwonetsa ng'anjo yosambira yagalasi yopitilira mtundu wa pusher. Mu gawo lotentha la chitofu, galasi losungunuka lotentha kwambiri limasungunuka pansi pa ng'anjo, ndipo billet imatenthedwa pambuyo pokankhira mosalekeza kudzera mumadzimadzi agalasi. Chifukwa cha kutetezedwa kwa galasi lamadzimadzi, billet sichikhala ndi oxidized panthawi yotentha, ndipo billet ikankhidwira kunja kwa galasi lamadzimadzi, pamwamba pake imakhala pamwamba. Kuphatikizidwa ndi filimu yopyapyala yagalasi, imalepheretsa okosijeni yachiwiri ya billet ndikuyipaka mafuta panthawi yopanga. Njirayi ndi yachangu komanso yofananira pakuwotcha, imakhala ndi ma okosijeni abwino komanso kutulutsa mpweya, ndiyosavuta kugwiritsa ntchito, ndipo ndi njira yotenthetsera yopanda okosijeni yopanda okosijeni.
3, Kutentha kwapakatikati koteteza (kutentha kwachitetezo chachitetezo)
Chophimba chapadera chimagwiritsidwa ntchito pamwamba pa chopanda kanthu. Akatenthedwa, ❖ kuyanika amasungunuka kupanga wandiweyani ndi mpweya ❖ kuyanika filimu. Zimangiriridwa pamwamba pa chopanda kanthu kuti zilekanitse zopanda kanthu kuchokera ku mpweya wa ng'anjo ya oxidizing kuteteza okosijeni. Billet ikatulutsidwa, chophimbacho chimatha kuletsa okosijeni yachiwiri ndipo chimakhala ndi mphamvu yoteteza kutentha, kupewa kutsika kwa kutentha kwa billet ndikuchita ngati mafuta opangira mafuta.
Chophimba chotetezacho chimagawidwa mu zokutira zagalasi, zokutira zamagalasi za ceramic, zokutira zachitsulo zamagalasi, zokutira zachitsulo, zokutira zamagulu, ndi zina zotero malinga ndi kapangidwe kake. Chogwiritsidwa ntchito kwambiri ndi zokutira magalasi.
Zopaka zamagalasi ndi kuyimitsidwa kwa mtundu wina wa ufa wagalasi kuphatikiza pang'ono chokhazikika, chomangira, ndi madzi. Musanagwiritse ntchito, pamwamba pa chopandacho chiyenera kutsukidwa ndi sandblasting, etc., kotero kuti pamwamba pa ❖ kuyanika ndi opanda kanthu akhoza kumangidwa mwamphamvu. Zopakazo zimagwiritsidwa ntchito ndi zokutira zoviika, zokutira burashi, kupopera mfuti, ndi kupopera mankhwala a electrostatic. Chophimbacho chiyenera kukhala chofanana. Kunenepa ndi koyenera. Nthawi zambiri, ndi 0.15 mpaka 0.25 mm. Ngati zokutirazo ndi zokhuthala kwambiri, ndizosavuta kuzisenda komanso zoonda kwambiri kuti musaziteteze. Pambuyo kupaka, mwachibadwa zowuma mu mlengalenga ndi kuziyika mu uvuni wochepa kutentha. N'zothekanso kutenthetsa billet mpaka pafupifupi 120 ° C musanaphike kuti ufa wonyowa uume mwamsanga mutatha kugwiritsa ntchito ndikumamatira bwino pamwamba pake. Kutentha koyambirira kungathe kuchitika pamene zokutira zauma.
Chophimbacho chiyenera kusungunuka mokwanira, chowundana, komanso chokhazikika pamankhwala kuti chiteteze bwino ndi kudzoza kwa magalasi otetezera magalasi. Pamene magawo osiyanasiyana ogawa magalasi ali osiyana, thupi ndi mankhwala zimakhala zosiyana. Choncho, kugwiritsa ntchito kumadalira mtundu wazitsulo zomwe zimagwiritsidwa ntchito komanso kutentha kwa kutentha. Sankhani bwino galasi zosakaniza.
Njira yotenthetsera yotchingira magalasi yakhala ikugwiritsidwa ntchito kwambiri ku China kupanga titaniyamu aloyi, chitsulo chosapanga dzimbiri, ndi ma superalloy aviation forgings.
