Yankho lowala la annealing loperekedwa ndiukadaulo wa angao limapanga H chowala cha anneal ed chubu chosalala mkati ndi kunja, kulolerana molunjika, mphamvu yayikulu, kukana kwa dzimbiri ndi zina zotero.Kodi chubu choterocho chingapezeke bwanji?
Chitsulo chosapanga dzimbiri cha Austenitic chimagwiritsidwa ntchito kwambiri m'malo osiyanasiyana aboma, mafakitale ndi ankhondo.Amapezeka m'mitundu yosiyanasiyana, monga mipiringidzo, ndodo, mapepala, mapepala, mapepala, zojambulazo, machubu, machubu, zopangira, flanges ndi zina.
Ngati chitsulo chosapanga dzimbiri chikutenthedwa mu ng'anjo wamba, gawo la chromium muzitsulo zosapanga dzimbiri la austenitic limachita ndi mpweya mumlengalenga kuti likhale wosanjikiza wa oxide wotuwa, wotchedwa 'scale', womwe uyenera kuchotsedwa ndi pickling.
Yankho lowala la annealing limatha kukulitsa izi.Kuti ziwoneke bwino, sungani zowala zachitsulo choyambirira ndikupewa kunyamula, zitsulo zosapanga dzimbiri za austenitic ziyenera kuwunikira motetezedwa kapena vacuum kuti zisawonongeke.Magulu onse achitsulo chosapanga dzimbiri cha austenitic amatha kutsekedwa.Malo oteteza amatha kukhala haidrojeni, ammonia osagwirizana, kapena nthawi zina vacuum.Mpweya wodzitchinjiriza umalepheretsa makutidwe ndi okosijeni pamtunda wa zinthu zachitsulo zosapanga dzimbiri za austenitic panthawi yolowera.
Chifukwa chake njira yowala ya annealing ili ndi zabwino izi:
1, annealing owala osati amachepetsa chitsulo chitoliro kuuma, kusintha ductility, kusintha plasticity, komanso yosavuta kudula ndi mapindikidwe ozizira.
2, sinthani kukana kwa dzimbiri pochotsa mpweya wa intergranular carbide, kuti mawonekedwe a pamwamba azikhala okongola.Kuyenga tirigu ndi yunifolomu zitsulo kapangidwe ndi zikuchokera, kusintha zitsulo katundu, komanso kukonzekera kutentha mankhwala.
3, chotsani kupsinjika kotsalira kwamkati muzitsulo, kupewa mapindikidwe ndi kusweka.
4. Oxidation ndi decarbonization zimachitika panthawi yotentha ndi kuziziritsa mu annealing wamba, kotero chitsulo chotenthetsera kutentha chakonzedwa mowonjezera, zomwe zimawonjezera kutaya ndi mtengo wazitsulo.
5. kupeza makutidwe ndi okosijeni owala, zabwino dzimbiri kukana pamwamba.Chifukwa annealing wowala ndi kutentha mankhwala Mzere zitsulo mu zoteteza mpweya wa haidrojeni ndi nayitrogeni mpweya kusakaniza, pamwamba popanda makutidwe ndi okosijeni amapezeka mwa mosamalitsa kulamulira mpweya woteteza mu ng'anjo.Poyerekeza ndi pamwamba omwe amapezedwa ndi annealing wamba ndi pickling, chifukwa palibe makutidwe ndi okosijeni, chodabwitsa cha chromium chochepa chimachepetsedwa pamtunda, ndipo kukana kwake kwa dzimbiri kumakhala bwino pambuyo popukutidwa.
6. mankhwala owala kusunga mapeto a kugubuduza pamwamba, sangathenso kukonzedwa ndi kupeza pamwamba yowala.Chifukwa cha annealing yowala, pamwamba pa chubu amakhalabe choyambirira chitsulo luster, wapezedwa pamwamba yowala, pansi zofunika ambiri, angagwiritsidwe ntchito mwachindunji popanda processing pamwamba pake.
7.Palibe vuto kuipitsa chifukwa wamba pickling njira.Annealed chubu sayenera pickling kapena mankhwala ofanana, musagwiritse ntchito asidi, palibe kuipitsidwa mavuto chifukwa pickling.
Ndiye tinafika bwanji kumeneko?
Zida za Online Fixing & Fusing (Anealing) zimatha kutentha chitoliro chosapanga dzimbiri 1050 ° C kenako kuziziziritsa ku kutentha kosakwana 100 ° C motetezedwa ndi hydrogen. + IGBT structure.With DSP digito control system, pali kudziteteza komanso kudzizindikira ntchito.Ndi voliyumu yaying'ono, imatenthetsa mipope mwachangu komanso moyenera ndi zinthu zopulumutsa mphamvu komanso zotayirira. zitsulo zimatha kupulumutsa 15% -20% mphamvu mosiyana ndi zinthu zina zamtundu womwewo. Kugwiritsa ntchito hydrongen ngati gasi mphindi iliyonse.
